content: I bought this scope a few months ago, what swung it for me was the trend capabilities of the Siglent over the others. The oscilloscope itself has worked fine, recording your data to USB stick worked flawlessly but when switched to the trend mode it's been a different story.My equipmentSiglent SHS806Software Version 3.01.01.33R3Hardware Version 1-31-3.3USB Sandisk Cruzer Fit 4Gb W95 FAT32 (0x0b)USB Samsung Mighty Drive W95 FAT32 (LBA) (0x0c)So here is my experience so far.I have already posted a message on here about the .DAV data file format and Siglent helpfully replied saying that they will add .csv to the trend functions in the next firmware update. If Siglent are listening Date, timestamps and scope parameters should also be included in my opinion.Scope RecorderThis function continuously records the waveform at a minimum time base of 100mS for internal memory (max 4mins and after can be copied to USB) and for straight to USB at a minimum time base of 2.5S (297 Hrs 31 mins for my 4Gb USB stick). BTW for the 100mS internal memory option the recorder can be set to record in a continuous loop. A useful tool i thought, but after leaving it monitoring a intermittent fault recording to USB i found it recorded nothing! The unit had switched itself off! So after running it again at home with me monitoring it i found that when the record time in the top left of the screen gets to exactly 60mins and 60 secs it freezes and the scope does not respond to any of the keys. Very disappointing!Scope TrendPlotSo whilst at home i thought i would see what the Scope trendplot would give me. This allows the recording of both channels using any of the 32 measurements alternatively you can record 1 channel with any 2 of the 32 measurements (volts, time, delay). I left it running with one probe attached picking up noise from my mains cables after several hours i saved the file to USB (.DAV format unfortunately). Then i noticed as i picked up the probe and touched the end with my fingers that "ParamA" set up to Vpp jumped to 5.02 Volts and stayed there until i let go and back again when i touched it??Meter TrendPlotThis seemed to be ok. Left it running with a probe attached near my mains cables and it did nothing strange. Saved the file to USB (.DAV again) and as i was on the file menu i noticed the load button. This must be how you look at the .DAV files i thought, so i stopped the trend and went back to see if i could load up the file i had recorded. Nothing! (i went back and it's the same with the Scope Trend Plot as well)It seems to me that maybe the recording functions were an after thought and not much testing has been done. It's a real shame as this would be really useful to me, maybe the Fluke scopes were they way to go for a hand held scope with trend capabilities but they are way out of my price range.

content: @ SiglentWould you like to comment on my post above?I would like to know what is causing these issues.The trend/record feature is the main reason i chose your handheld scope over the others out there.Perhaps it is me or my setup?

content: 1. We will change the file format from .DAV to .CSV in Scope and Meter trend plot mode.2. freeze at 60min 60sec, it's a bug. We have found it and will fix it.3. load function is used for load the setup file and update the firmware, not used for load the trend plot data file.

content: Ok, new firmware in 4 weeks great!Well may i take this chance to offer some ideas to Siglent to improve the usability of the SHS serires.1. Record all the parameters used in the new csv format. date and timestamp would be useful.2. In the save/recall operation it is sometimes confusing trying to use the cursor keys (eg up cursor moves right). It would be nice to use all 4 cursor keys to move in any direction and the function keys to select, backspace and the rest.3. When saving a JPG of the screen could the menus be automatically removed because i have sometimes forgotten to de-select (menu button). When i view them on my pc i find they are obstructing the lower half of the screen. (i know its lazy but it is easy to miss)4. The oscilloscope trend reliability. does it matter what the timebase is set to before you start oscilloscope trendplot?Thanks again Siglent for listening hope you can look at some of these items.

content: Hello. I bought SHS806 about a week ago. It works OK, however I have some problems to save the waveform as an image.1. It was needed to reformat my USB drive, so as to have 2gb partition (FAT, not FAT32). Before this operation I was unable to save any files and create folders.2. After that I was able to save data in csv format, but saving bmp is a problem. If I save only once the image, on the PC it has 0kB size (on the scope is 219). After reinserting the flash into the SHS806, it reads the image as 0kB also. I've found that I can make two consecutive images, and then the second is 0kB large, and the first is 219. However it doesn't contain the waveform.Here I attach an image, which should contain the square signal from the calibration output (the second channel is turned off).SW ver: 3.01.01.33R3HW ver: 1-31-3.3Ser No: SHS80003130093If possible, tell me where I can download newer firmware, also the flashing procedure.Thank you!

content: I have never had 0Kb BMP file but i have had BMP files with everything but the waveform like your attached picture.Sometimes when i try to save a BMP the waveform disappears and a empty screen is saved. This is rare but i did notice at the point when the save button is pressed the waveforms disappear and then the screen changes to the file manager. I try again and it saves the BMP correctly.I hope Siglent sorts these things out with the new firmware (maybe upgrade us to the 200MHz like the other DSO hacksOr they could just send me an isolated version if they like and i will test it for them.

content: Hello again. I confirm that the last saved image is (always) corrupted. Today I've made 19 images (long pressing "save/recall") and the first 18 of them are fine. The last one has 0kB size. I'm using only the first channel and FFT. On all of the images FFT line is present. On 3 of them, the signal from CH1 is missing (like the image I've attached before).

content: I have tried to re-create your situation with the compensation usb adaptor fed into CH1 and FFT. Out of 20 saved BMP's 2 were without CH1 but with FFT (same as your attached BMP's).I did about 40 or so saved pictures in total but none of them were 0Kb in size?

content: That sounds promising, i will update mine and will post my experience on here.@someother i think he is after pictures of the inside of the scope so people on here with experience of oscilloscopes can evaluate the unit (eg safety standards)I may take mine apart at some point but i am very busy at the moment. It would be nice to see one of the isolated versions though as Siglent say they are targeting Flukes dominance in the market with their specialized isolation chip.From their websiteQuote

content: I have successfully updated my firmware, the DAV format has now been replaced with CSV.The only other difference i can see is that there is an extra page on channel setup. You can now choose the unit volt or current and something called skew? (between -100nS and +100nS)Is it not the same as adjusting the M position?

content: Well i have a had play around with my firmware updated SHS806 and its been a disappointment.Here is the list.1.CSVtrend file needs timestamps for the samples. (see attached csv's below)Multimeter Trend2.Scope Trend. Had this running for a while and after around 1hr 40mins the trigger level started to move up all on its own (along with beeping) and then it decided to save the file all by itself! There is something really screwed up with this feature, i left it running all night and in the morning the unit would not wake up out of screen saver mode. So i powered it down and when i switched it back on the siglent splash screen came up with the scope screen slowly revealing itself slowly by one column of pixels at a time left to right across the screen. The USB stick was also flashing away all night at about 2 sec intervals. Oh and as you can see below the csv is screwed up as well.3.Multimeter Trend. Seemed to work fine at first but then if you move the cursor around you get peaks in the trend which you can reproduce (see BMP below testing a battery) Also when trying the other keys you can get the 4.181V i was measuring to instantly turn into 4.181mV or even 100K ohms!!!4.BMP saving. The image saved sometimes does not have the waveform displayed on the screen. (see below)On Siglents website they say they are breaking into Flukes territory with these handheld scopes well i am sorry but you have a long way to go. I class myself as a novice user but they should pray that Dave or mikeselctricstuff doesn't do a teardown of these models as they would surely find other things wrong with these units.
