content: Looked like crazy over the net and have not been able to find reviews on the Siglent SHS810 hand held scope, the close I have gotten are Russian youtube reviews. I would foremost like a actual SHS810 user to chime in and tell me does the scope live up to its specs. For example how long does the multimeter take to get a reading on a cap, resistor, continuity, etc. Is it really a 1 gs/s 100mhz band scope. I have the need to magnify waveforms so is there aliasing issues.I would secondary like a opinion on the hantek hand held scopes namely the hantek 1060 and 8060 as far as reliability and if or not can you actually measure a 60 mhz non repetitive waveform with their real time 150 ms/s sample rate.Btw I am not interested in a bench scope, I am exclusively interested in a hand held scope.

content: There has to be Siglent SH810 user on these forums, could you answer these questions about the scope meter. Please guys don't recommend alternatives, I am only interested in the SH810 as I want a scopemeter and the Siglent is in my price range and it specs are what I am looking for.Lets start with the multimeter. How long does it take to get a AC/DC, resistance, current, capacitance reading using the auto range option?, can it give you a reading on all these measurements by the time you count to 3. How accurate are the readings? How good is the cotinuity check, can you get a buzz if you scrap the lead together very very quickly.Now for the scope. Is this meter actually a 100 mhz meter. Can you input a 100 MHZ analog signal into the scope and get a 100 mhz undistorted wave on screen single channel of course. Does the scope actuall have a 1GS/S rate? How about the memory depth, is it actually 2mpt. I do alot of digital troubleshooting and for example I constantly need to capture frequencies in the 25-40Mhz range and analyze for glitchesHow is the battery life.Thanks for your help

content: Guys I appreciate the input and I'm not trying to be ungrateful but I very clearly stated I wanted no alternative scope recommendations and I'm utmost adamant about that. I truly do not want alternative recommendations because I'm pointed toward scopes that are far far outside my price range or specs that are far far below my requirements. I don't have a grand to spend and I don't care about isolation as I will be primarily using the scope for single channel digital trouble shooting and yes I do need a hand held not a bench model. To reiterate I do not have a grand to spend, $500 is my max. I need the scopemeter right now, I don't want to spend a grand nor do I have the time to save it up if I wanted to spend it and the siglent 810 is available to me now and looks like it meets my needs on paper that's why I am asking for feed back on the Siglent SHS810.If you can point me toward a scopemter with dual channels, 100MHZ bandwidth, 1Gs/s and at least 1mpts of memory depth, standard math functions and if you like but I'm not concerned for isolated channels and lastly but just as important a decent multimeter function for $500 max I will thank you in advance otherwise I would just like info on the Siglent SHS810.Take the recommendation of the THS720A. That scope only has a 500ms/s as opposed to the 1Gs/s of the Siglent for one example.I actually did try a hantek scopemeter btw, the meter function was horrible, slow continuity and auto ranging on ALL measurements. For example damn thing took ten seconds to get a capacitance reading on a out of circuit cap and it could not even get a reading on caps that were still in circuit when all my other multimeter could. The hantek continuity check was so slow it was useless. I had to continue to carry my fluke multimeter with me. I returned the hantek because of this.

content: Quote from: tautech on December 16, 2013, 02:43:10 amThank you, Thank you sirIf you would be kind enough to tell me a few more things. What is your impression of the scopemeter, does it meet your needs.How high of a analog signal have you used it with and how accurately displayed and calculated were the signals that you have actually used the scope with. At 1Gs/s you should actually be able to work with a 100Mhz analog signal single channel.I know the SHS810 has a YT and XY format does it also have a roll mode in which the oscilloscope horizontal scan updates from right to left very slowly like a EKG.Memory depth is so so important to me. The scope advertises 2mpt of depth. I tend to work with frequencies in the 25-40Mhz range. So if I wanted to capture 1ms of a 40mhz signal to analyze I would need 80K of depth and the siglent would have more than enough memory for that application. Have you ran any similar analytical test with your SH810? If this thing lives up to its spec it will be all that I need and I am gladly willing to pay the hand held premium if it does.About the multimeter, can you get the meter to read capacitors that are still in circuit (powered down and discharged of course) and how long does it take to do that, is it still 1 sec. I am assuming those time scales you gave me are for auto range and not manual. Is the 10amp connector fused.Equally important how long have you had your 810? Has there been any electrical/mechanical issues with the unit? How sturdy is the unit? How is the battery life.EditIt took 10 secs to get a reading on a 1000 micro cap,. How about a 470 micro electrolytic cap.

content: Quote from: tautech on December 16, 2013, 06:50:16 amThanks for that bit of good news about the horizontal roll.So essentially the multimeter section is just as crippled as the one on the hantek even more so because the hantek at least had double fuses. Out of all the features available on any multimeter I use the continuity check the most and its vital I get a reading in micro seconds upon touching the leads together. This is of the most vital importance when looking for shorts. The 10 amp connection on the siglent is unfused which is a death sentence for the scope and the capacitance meter isn't even worth bothering to use since all the caps I work with are between 220 micro - 1000 micro farad.At this point the only saving grace is the actual scope going by your review and my trusting fluke multimeter will just have to complement it instead of being retired. I will sleep on the purchase tonight.I might hit you up on some more questions I might have forgotten, thanks for your help man

content: A couple of closing points.Just noticed now good the viewing angles are... without measuring around 45 degrees in any direction.re un-fused 10 A ranges. That can be addressed with fused test leads.The factory soft case option is a beauty, about 300mm square by 100mm thick and houses everything that comes with it and you could include a few extra cables & leads.The scope does everything you would expect and is quite really usable despite not having knobs. UI is not sluggish at all.After a couple of hours getting some answers for you the battery indicator is showing about 2/3 full.Hope this all helps.

content: The Scope uses a separate board for the DMM part as shown in the picture. The DMM is a single chip manufactured by Fortune and the manual is here:http://www.ic-fortune.com/upload/Download/FS9922-DMM4-DS-11_EN.pdfThe DMM is a 6000 count DMM and measures up to 3 times per second for the digits part and up to 30 times per second for the bar-graph part. I don't know how the DMM sends info to the display as the chip can drive its own display or it can be controlled by the RS-232 port, probably that is why is so lagging. Mike from Mike's electricstuff had a couple of owon Handheld scopes and the DMM was totally unusable on those units. I Own a Fluke 199C and fortunatelly have none of those problems but it is also Xpensive and doesn't have the deep memory of the Chinese scopes.

content: Thanks for that, i've had a read of the FS9922 datasheet and i can now see why it's relatively slow at updating and that the unit communicates by RS232. I noticed as well it can measure temperature with a K type thermocouple, pity Siglent didn't add this feature to the SHS806 as trending a temperature over time would have been really useful.Although in standard meter mode it measures at 3 times per second It looks like in multimeter trend mode it uses the bar graph update at 30 measurements per second but reduced to a max sample rate of 10Sa/s. I assume this is because its communicating to the display on RS232 and as the buttons are multifunction between the scope and meter they are also on the same data lines.So with that knowledge it may answer my question.Why in meter trend was i getting large changes to a battery voltage just by moving the cursor? (see image below). I think by pressing the cursor key whilst the trend is running is causing a data collision on the RS232 comms.Your very lucky to have a Fluke 199C i think i would trade reliability and trust for the deep memory of these units (just recently it has started to lock up on me, firmware could be better).

content: I just purchased the siglent SHS810 and I am regretting it worse than that hantek DSO purchase I made earlier. The multimeter section of the siglent is totally screwed up out the box. The scope portion is working but the meter section is locked up. In meter mode the value of 1.0 is locked on the screen, no i do not have the unit in stop mode. The unit is stuck in manual configuration on the measurements and continuity checker is constantly latched. I can not take a single measurement because the whole multimeter is locked. I upgraded the firmware and it has the same issue. When I can manage to scroll to DC current measurement the number 1 keeps randomly flashing.

The problem I was having with the Shs810 was not isolated to my scope or even the model. Another user from Russia with a Shs806 discovered that the crystal controlling multimeter section on his scope had a cold solder joint. Examined my shs810 and discovered the same thing. I retouched the joints and the shs810 has not acted up since.

Than again if the 2510 has a multimeter that works out the box without the need for the buyer to step in and fix it well that alone is a big improvement.Your only hope with those BK branded Siglent's scope is if things go bad within the warranty period since it is a BK branded product than BK will actually honor the warranty.My Faulty Siglent SHS810Russian guy Faulty ShS806

content: @Zensei:I own a Hantek DSO1122S and it does not have the "trendplot" function the Siglent scopes have (at least as the firmware stands now). Also, my scope has only 1mb of memory, not 2mb. Even though I have seen 2mb advertised in some listings here and there, I have not been able to find anyone that actually has one with this capacity. Apparently, the scope can be modified to 2mb by swapping a chip inside.In general, isolated inputs are preferable for working with mains voltages. It is a huge and important safety subject too complex to go into here. You must totally understand what your equipment limitations are and how to connect to high energy circuits. For me the probes matter very much. They must be very well insulated. I found the probes that came with the Hantek to be barely acceptable. I use high quality ones like Fluke VPS series (there are similar available on the 'bay. Search for "insulated oscilloscope probe"). I am also suspicious of the "cat" ratings on these scopes. I also own a Fluke 199C, and use that when there is any question about a high energy circuit (and also for trendplotting).After reading this thread, I am happy to have gotten the Hantek, though. It worked fine out of the box, and has been very useable. As always, the firmware can be improved. Hantek does seem to listen to their users, at least. It is far and away better than the Fluke for things like screen/data capture. I like the 640x480 black screen background better than the 320x240 white screen of the Fluke. I admit I never use the meter functions on these scopes though. I always have my Fluke meter with me!Just my 2-cents worth...

More info in a his previous posts.His experience was also compromised by the fact he had bought online and support was not available.A good lesson to all of us.

content: @ZenseiIf you set the Hantek DSO1000B/BV/S series "Longmem" to a larger size (1mb for single and 512kb each for dual channel), you can freeze a frame and send the wave data to the USB flash drive. This can be recalled and zoomed in on. You can also save it as CSV data, although I haven't tried this yet to see if it works. You can only use 4k and 40k point memory in roll mode, though, so depending on what you are trying to capture, there may not be as much detail as a traditional trendplot might have.The scope also allows you to record up to 1000 "frames", and save them to a USB flash drive. The implementation of the record function is pretty clunky, though, and needs some firmware work. The controls are laid out inconveniently, like the "Start" and "Stop" soft buttons are on different pages! Makes it hard to navigate. Also there is no frame by frame advance. I have been sending these reports to Hantek and they are accepting them with a promise to improve the next firmware version. We can always hope......The SD slot thing is strange to me. If the option is installed, its internal, so you have to take the scope apart to change it. I guess they view it as semi-permanently installed memory.

content: Quote from: Zensei on January 19, 2014, 10:53:52 amDuring my closing emails from SIGLENT China the best they would do for me is replace my shs810 100mhz scope with a shs806 60mhz scope because they had no available shs810, now does that make any sense. The Siglent tec tried to convince me that going from a 100mhz band to a 60mhz band after I freckin paid for the 100mhz band is not a down grade and no I was not offered back the difference in price.Bottom line is Siglent as a company did not solve the problem, a problem that was a result of their manufacturing. I am pleased with the scope now that I had to personally get it working but as a result of horrible customer service I will never buy from Siglent again. If you buy Siglent make sure you can return it to the seller if it goes bad on you and pray that if it does go bad it does so in the return window because beyond that you are at the mercy of Siglent warranty and their mentality with me with a product I bought defective out the box was "you got a bad brand new unit fix it your damn self" which is what happenedThe scope as it sits now is fully operational after intervention from me.Now that I got the DSO working my opinion is as follows. The multimeter is worthless, continuity is too ungodly slow to be of any use and to double down on top of that it is not a continuous tone. I can not stress how vital a quick & continuous continuity check is of the UTMOST importance in my line of work when looking for shorts and opens. There is no way on this earth that this feature on SHS810 can meet me a tenth of the way for this role in even a last resort capacity, a role even my little pocket radio shack meter can do better. Capacitance is just as worthless because it will take 12 seconds to get a reading on any value over 200 micro and between those 12 seconds the meter will stop on a measurement for 4 seconds which would lead you to believe it is telling you the value of the componet. I don't have the nerve to take a current measurement because the 10 amp isn't fused. About the only functions that are just barely useable are ACV, DCV as long as you don't need accuracy beyond a tenth of a volt and resistances measurements. I should at this stage point out the the multimeter in this DSO is physically a single chip on a module.The good thing about the scope is the the actual scope section. I was actually able to use it for fault analysis to reliably capture glitches in a digital design. I did a side by side comparison with a tektronix TDS2012C and although the SHS810 when tested at its max band of 100MHZ has more of a aliasing issue than the TEK this draw back was still not substantial enough to prevent me from capturing random intermediate glitches at the 90 MHZ band of the 810. The Pk-Pk value of the 810 was only off by 5% over a range of voltages when compared to the TEK. My only complaint is that in order to use the deep 2MPT of memory the scope will automatically drop the sample rate to 500ms/s to do so but this was written in the manual. This positive feedback is of course contingent upon the scope continued operation and not suffering anymore electrical faults in the near future unrelated to user operation.All my work is at the CATI and CATII level, I don't play around with anything higher than that. I don't neccisarily need isolated channels as the only electronics I will encouter in which floating measurements are needed is switching power supplies but in that situation since it is a handheld DSO with no earth ground I can use one channel of the scope to do so. Siglent does make SHS models with isolated channels but they are vastly more expensive than the non isolated versions.In your case I would not go anywhere near mains without a isolated scope. Even though you can use one channel ALONE to make a floating measurement with a handheld non isolated scope you might forget this and go 2 channels one day one a piece of equipment with different grounds by mistake.BTW, having previously owned a hantek handheld DSO1060 for 3 weeks I can testify that although the device worked 100% out the box and for the whole duration of time I owned it, the multimeter section was only marginally better than the Siglent but still unusable and I imagine the multimeter design in the hantek is the same in ALL of their models. To the hantek credit the 10amp connection was fused though. The short comings of the scope section of the hantek was a result of its low spec but that was my fault for still buying it knowing those parameters. Newer designs such as the 1062S you mentioned have SUBSTANTIALLY higher samples and memory but I can not offer testimony to their performance having only owned the DSO1060. For anyone reading thisdon'tbuy the hantek DSO1060 or DSO8060 because their sample rate and memory depth are horrible.

content: Hi, thanks for your answers...I'm considering this isolated frontend from Siglent in combination with a non-isolated scope, as the isolated Siglent scope is too expensive, when the Hantek is also isolated and less than half the price, plus it's hackable.I really like the Siglent design and layout, whereas I think the Hantek look a bit too toyish.What is your opinion about the menu system on the Siglent?I think I might end up ordering them both and test them out before choosing which one I want.

content: I have the SHS806 along with a differential probe for mains voltages, i have experienced no issues with the scope and the multimeter has it's limitations as previously stated. However the Recorder functions are a disappointment (https://www.eevblog.com/forum/testgear/siglent-shs806-record-problems/I have contacted Siglent and are waiting for a reply (only a week). If you are looking at the trending functions of these units then i would hold back until the firmware has been sorted.Regarding the menu's it has locked up on me a few times they all happened when i was using a recorder function (scope trend or scope recorder).
