content: Hello to everybody,I´ve purchased Rigol DG1062Z arbitrary generator. Everything works fine, except the reproduction of arbitrary signals, created in Rigol official softwave (UltraStation). I've tried to reproduce the sine function modulated by Hann window, in Matlab, the record of the file is OK (see attachment). However, when I use the file in the generator, it creates stair-step funciton. If I generate the same function in the generator in itself, everythings is OK. Could someone please give me the advice, where the problem should be?Mike

content: How many sample points are in the file? Once you have that number, think about what it means. The entire waveform is broken up into just that number of samples. Does that represent what you see on the screen?

content: I loaded file pokus.txt into Ultrastation software, and then downloaded it to DG1032Z over USB...Looks fine that way...Both .csv and .txt files load with resolution reduction.Interesting is that also on a generator you cannot save as .txt or .csv only as .RAF file..RAF files work fine in both load and save in full resolution...You can load .txt file in Ultrastation software and save it as .RAF file on a USB stick, and load that directly on a generator. That works fine.So on a generator (DS1000Z series), you cannot save localy on a USB stick as .TXT and .CSV. Also, if you load wave from .TXT and .CSV file form stick, it gets loaded decimated to what looks like 60 points horizontally..I would classify this as bug..Regards,Sinisa

content: Dear 2N3055,you´re absolutely right! I´ve tried to generate a wave via Ultra Station software, store it in txt and raf format, copied them onto USB stick and finally downloaded them into generator. The txt format created the stair/step structure and the raf format was fine...As you´ve said, it must be definitely a bug.
Rigol DG1022Z and Vpp - Page 1

timestamp: January 06, 2018, 12:18:32 pm
content: Hi,I recently bought the Rigol DS1054Z and the DG1022Z and experimenting a bit to get to know them better. I also bought a second BNC cable to connect both channels to the scope.The question I have is regarding the separately bought BNC cable, when choosing a sine or ramp wave, all looks good. When choosing a square wave it seems that this cable gives a spike at the beginning of each period, so for example when then generated wave has a Vpp of 5V, the scope sees a Vpp of 7.08 V. And the overshoot is around 50% instead of 1-2% with the included cable.I don't have this issue with the included BNC cable. I swapped cables to be sure but behavior is only with 1 cable.Any explanation for this?Thanks for any help or feedback.Alex

content: The 1022 is a 50 ohm Z. The 1054Z is basically a 1M ohm z,so you need a thru terminator on the 1054Z to make it look like50 ohms. So transmission line (the cable) is properly terminated.https://www.pasternack.com/50-ohm-feed-thru-load-terminations-category.aspxOr build a DIY terminator.https://www.eevblog.com/forum/projects/home-made-feed-through-terminator-for-bnc/http://web.cecs.pdx.edu/~greenwd/xmsnLine_notes.pdfRegards, Dana.

content: A long time ago I put a 12cm fan in my Rigol DS1052E, and mounted it diagonally in the cabinet.There is plenty of space to fit this bigger fan. It just needs some pieces of cardboard to prevent the air from circulating from the back to the front of the fan.These bigger fans are also much quiter for the same airflow.I probably put a resistor in series to lower sound eveven more, I may have put in an LM317 and a pot for easier adjustment.I also may have tied the fan itself down with come pieces of string to decouple it from the metal housing.Be careful with tape or other materials that deteriorate over time.You can do a lot with cardboard and a few staples. It does not look nice, but nobody has to see it and it is really quick and effective.
Rigol DHO814 Sample Rate Not 312.5 MSa/s - Page 1

content: I have a new Rigol DHO814, 4 Channel oscilloscope. The manual states that 312.5 MSa/s real-time sample rate in all channels mode (3 or 4 channels). However I cannot get it to work anything better than 62.50MSa/s when 3 or more channels are enabled. Is this a bug? I am changing the Memory Depth to try and get the sample rate, but nothing I have done will let me get the 312.5MSa/s no matter if I have 1, 2, or 3 channels enabled.

Note well here the words 'maximum', and 'up to'.As user 'tunk' has suggested, the *actual* sample rate used is dependent on both memory depth and timebase settings, and will not be maximal for all combinations of settings. Try a faster timebase and see what you get.

There is "last" setting in my DM3068, not auto power on, but it remembers it's last state before power was disconnected. And will act accordingly when power appears again. Maybe this is somehow related to this setting.

content: I am trying to repair a desktop multi meter that fails on virtually every self test. One of the voltage regulators, L7915CV, seems to be really hot and makes a smell. I removed it from the circuit and tested. The output is -17.02 V (input -25v). Is this within spec, or can the 2 volt different account for my problems? Note that the unit powered on and got the same test results even with the voltage regulator not on the board.

content: I'm on a hunt for a triple bench supply to upgrade my older Farnell LT-30.Main reason for updating is the digital readout and finer resolution of the voltage setting.(I'm tired of constantly having to have my multimeter plugged in to the supply to set the voltage or current limit accurately)Other features are welcome but not necessary at this point.I strongly considered the DP832 mainly because I already have a DG1022z and a DS1054z so I thought they would at least look good together:PFrankly though, I've had a blast with the above combo and no issues at all so getting a PSU from Rigol would seem like the sensible thing to do until I saw about a few problems concerning this PSU namely the infamous output spike, the non isolated third supply ( not really a big issue for me) and the various issues Dave mentioned on his videos.All in all the Rigol seems like a solid supply albeit a bit pricey considering its minor quirks.In my opinion if it was priced near the Ds1054z it would have been a lot more popular.Anyway, I watched a YT video of a guy replacing his DP832 with three Korad supplies and he seemed to be happy with his choice so I thought about this as well.My only gripe with three separate supplies would be how to have the three outputs turn on simultaneously apart from the obvious; having them on the same power strip and turn the strip on.I'd really like some opinions on the matter since I will be making a purchase very soon..Main use is a little bit of everything be it college projects, MCU stuff, analog audio circuits, repairs, digital and logic circuits etc.

( I'm afraid that 2072A is too old project and will be soon replaced by Rigol)Thanks a lot!!!AH... which one allows readings at hightest frequency? ( i know the 1054 can see 400/500 mhz...and the 2072a? )Only for testing purpouse,obviously not for "precision" and accurate measures

The Siglent SDS1072CML sells for €253 ex VAT .I've compared the datasheets of both scopes  and there doesn't seem to be much between them. That shouldn't be a surprise since both have been designed and manufactured by the same company.They both have a 1GSa/s sampling rate for 1 channel, 500MSa/s for 2 channels (Dave's #1 most important DSO requirement, see EEV #13). The Rigol has 1Mpts deep memory, the Siglent has 2Mpts (Dave's #2 most important DSO requirement). Is the 2Mpts worth the extra money?

content: Siglent SDS1072CML is a mature product like the DS1052E, both well liked but the Siglent has a 7" screen. This is the way many DSO's are going, meaning when the Menus are on screen you still have a 5" display.The newer DS1054Z mentioned had a problem that required a firmware update and this created problems of its own. One could say this product is not yet mature.It is a 4 Ch unit with all 4 shared by one 1 G ADC. This lowers the sampling rate with all channels on to 250 Msa/s.

I think that in order to obtain more functionalities from the oscilloscope, you have to write your own Labview software using VISA drivers. The Ultrascope software is a bit limited, IMHO.If you want to capture screens and record waveforms, a USB memory in the front can help.

I have never heard of AxB until I saw it on the Rigol.What is the application for such a feature?Since I have your ear. If I don't want to use the PC remote feature is there any other reason for loading the software on my PC?J.P.

Even 100MHz signal on 100Mhz scope most likely will not show at correct amplitude.

The wire loop becomes a (poor but functional) near field probe. It needs to be placed very close to the circuit, and orientation does matter. You may even try to coil the ground lead into a little loop.

VisaDSO can save for you 1 byte per sample (space efficient) using its standard *.vidsoc file format, or/and later you can export to CSV format for matlab or excel import. whichever you prefer.3) you can do zoomable and peak/harmonics search 200Kpts FFT and 15Kframes/sec level grading simulation (intensity grade and color/thermal grade) in currently published lite beta version, totally free and time unlimited.

Rigol DS1054Z and MSO5000 60MHz square wave difference - Page 1

timestamp: June 21, 2023, 04:07:18 pm
content: Hi there! I have a DS1054Z (upgraded) and a brand new DSO5000 (upgraded) and out of curiosity, I wanted to compare the difference in measuring a 60MHz 1Vp-p square wave signal from the Siglent SDG1032X generator (upgraded to 1062X). I'm using a cheap 1-meter RG58 coaxial cable and a 50-ohm terminator at the input of the oscilloscope. Attenuation set to X1 and all other settings are the same for both measurements. I'm wondering why there is such a small difference between the waveforms on both oscilloscopes. If the MSO5000 has a bandwidth of 350MHz, it should be able to display more harmonics. Or am I overthinking it, and there will indeed be such a modest difference compared to the bandwidth difference, or perhaps the Siglent generator is to blame in this case or maybe the coax capacitance? I also did a measurement using a compensated x10 PVP2350 probe for comparison (last pic).What are your thoughts on this?

In other words, your signal source doesn't have high frequency harmonics which is required in order to see difference at higher bandwidth.Use ADF4351 synthesizer for testing, it has about 70 ps rise time. Or at least si5351, it has 1 ns rise time.

content: ok, I'm assuming I'm doing something wrong here.I have been using my scope to see the effects of decoupling capacitors in some simple switching circuits. I'm a noob paying my dues and this has been a great exercise.The only thing that bugged me was that I was having to reposition my traces a lot after changing the vertical scale. I'm watching a 5v signal at 50mv/div and want to get into 10mv/div and then my position changes from -5v to something else and I have to wind the position knob to get it back to -5v.It seems to me that the viewing window is pivoting around the 0v point which makes sense when you are viewing an AC curve or something like that but when you're studying something that is centered around another voltage it becomes a lot harder.Is there something I can do to help this? Pivot around a cursor? or a reference mark perhaps?Cheers,Jase

content: Hi,I do not completely understood what you have written, but I would interpret your question as:"I connect GND to probe tip and scope still shows some small voltage. Why is this happening? Why voltage shown is not zero?"I think this is happening: scope is sampling at very fast timebase (10ns/div) and pick ups (from environment or from internal error sources in signal path) small error. This error is largely attributable to digitisation error/noise.Remember than scope has 8 bits resolution (=256 different values, actually even less). Minimum resolution on 5V/div range is (5V * 8 vertical divisions) / 256 data points ~ 0.16V. Thus few bits up or down can create 600mV.Math functions then just show statistics ("average" view of this noise).I would consider such behaviour as normal. DS1054Z is known to have some offset on all channels depending on which are turned on/off. It is not an indication of error or fault in oscilloscope.I suggest to remove "Poll" from this message, it adds no value.

content: It's because it achieves 1Gsa/s by interleaving multiple ADCs (I can't remember how many, look it up if you're interested) with a lower bandwidth. With only one channel activated, all the ADCs become allocated to that single channel, so the sample rate can be higher, than with two channels activated. I can't remember whether activating three or more channels limits the sample rate even further, but someone else here will know.

I sending a short 20ms pulse to open the valve and trigger at the scope. Everything was fine until I set the scope scale to 500mV/div. Readings has unexpectedly changed and I have no idea why. I figured that the "transition" occurs between 750-760mV/div. Higher scale is ok (800mV, 1V, 2V...), but the "750" and below causes bad readings.I know it sounds strange but please take a look at pictures and tell me what you think. Why a simple change of scale effect on the results? Is it something I'm doing badly?Setup:DS1074Z @ default settings, sw 00.04.01.SP2, hw 0.1.1http://www.ecs.umass.edu/ece/m5/images/TIP122_transistor_schematic_S.jpgMeasured between GND and tip122 collector, pulse duration is 20msScreen captures:pic_01 (5V/div)pic_02 (1V/div)pic_03 (760mV/div)pic_04 (750mV/div)pic_05 (500mV/div)pic_06 (300mV/div)Problems do not occur in other cases (at least, I haven't yet noticed ...). It seems that this particular example is somehow strange ...For example, if I measure the base of a TIP122 everything is ok. The duration and all the rest are correct.I'll be grateful for your help.
