content: I posted this Utility in the Rigol DS1000/DS2000 jitter thread and since it seemed to attract some interest I figured I'd start a new topic.Its written in Labview so you will need the Labview RTEhttp://www.ni.com/download/labview-run-time-engine-2014/4887/en/Looking at the VISA commands this should also be compatible besomewhatcompatible with the entire DS series from Rigol. I would expect the Real-time Capture to have no issues but there may be problems with the Long Memory Capture on other models scopes (I am using a DS1074z). If you have a DS2000/4000/6000 please test this and let me know.Current Version V2.2.3Rigol V2.2.3http://s000.tinyupload.com/index.php?file_id=90659414641703074947Rigol V2.2.1:http://s000.tinyupload.com/index.php?file_id=06194785972356290806Rigol V2.2Download Link:http://s000.tinyupload.com/index.php?file_id=16159701921368811937Source:http://s000.tinyupload.com/index.php?file_id=05957966868497599811Known Bugs:Long Memory Capture only supports one channel at a time and trigger channel must be the same as capture channel. For now it is a good idea to disable other channels when using this.Memory Depth setting is only updated when a new menu selection is made.In real-time capture mode changing channel options sometimes results in a communication error, stop cont. sampling before changing memory settings to avoid this.Waveform statistics cannot compute more than 3Mpoints of data (labview limitation) currently statistics are calculated from the first 50Kpoints to improve speed.Rigol DS1074z Bugs:Scope complains of 'Invalid Input' but processes commands anyway. (Perhaps I do not known the exact sequence it expects) commands work regardless.When using :WAV:DATA? to request samples there is an upper limit of exactly 1179644 data points that can be downloaded at any one time requesting more points using :WAV:START and :WAV:STOP will result in a no data being returned at all.Note this is when downloading the data as bytes ie :WAV:FORM BYTE, if using :WAV:FORM ASC (ascii) the limit is reduced to around 60Kpoints.However it is possible to download the entire waveform memory in blocks and this is the technique I have used to download more than 1.1Mpoints.

content: Dear AlessandroAU,your Utility seems to be quite cool!Unfortunately, being on a mac I can't run your tool (as it's compiled for windows).Would you be able to compile this as a mac app? (I don't know anything about labview, maybe you can just select this as output?)Thanks in advance!

content: Hi AllesandroAU,Unfortunately something broke between your original version and the latest (2.2). I cannot reproduce my original nice FFT.I compared both versions with identical scope settings. (same as the one you re-published)If I do a long mem capture (1.2 Mpts) the capture(buffer) in 2.2 is corrupt (see screenshot below).Also the FFT is obviously incorrect (even when based on the capture buffer). See the other screenshots.Also I see an almost permanent message on the scope screen: Parameter Limited! which indicates an input error.(also did a long memory capture with 12 Mpts, with scope also on 12 Mpts settings, see below. no difference).Do you need any more info from me to troubleshoot?

content: Quote from: pa3bca on December 18, 2014, 09:42:23 pmVery odd, it works fine on my unit.Can you confirm the following happens:1. Make sure only one channel is enabled and that the trigger channel is the same channel as which you are capturing from.2. When changing the memory depth the number the change is reflected under the acquire menu on the rigol screen.3. Does the run/stop button turn red during the capture and back to green afterwards5. Does channel selection on the real-time screen work for you?4. Does realtime and screen shot capture work for you?Also do you have 12mpoints or 24mpoints option on your scope?

After some buffer capturing all goes south, and nothing works any more (must restart scope and application te be able to capture again)3:Yes4:Realtime: Yes. Screenshot: No. Screen stays black. And after I try to get a screenshot I need to restart the application in order to be able to get a capture... (and realtime screen also fails).After trying a few time I suddenly got a better result. See screenshot. Although even here there are serious glitches in the captured waveform. The FFT here however looks ok.But right after that a next capture failed again.Yes I do have 12 and 24 Mpts available. But same results here

content: Mostly works on my DS2072 (HW v2.0, FW v00.03.01).The only obvious problem that I noted on a quick test using the scope's 1KHz probe calibration square wave was that, in the Long Memory Capture, there is a large impulse-like discontinuity between each sample chunk. It looks like the DS2000 scope wants total number of samples to be a 10x multiple of 1.4 instead of the DS1000's 10x multiple of 1.2.

content: Quote from: AlessandroAU on December 18, 2014, 11:21:05 pmSame issues. The first time I power up your program it works ok (1.2 Mpts). Also on 12 Mpts. There are a few glitches in the captured buffer but probably not enough to upset the FFT calculation.But if I then try 24 Mpts I only get a flat line in the buffer window, and nothing in the FFT window. And then the 12 and 1.2 Mpts captures produce the same errors as can be seen on my previous screenshots (hickups in the buffer window, and FFT way off).Screencapture still does not work. And after I try a screencapture the realtime display acts funny. Have to enable/diable it a few times for it to start again.Also the scope's screen is flashing errors like crazy (all versions of them)I have to restart both the scope and the program to get them to play nice again (but then only at 1.2 and 12 Mpts)

content: I am just curious if you guys thank that this could replace the need to purchase an actual SA?I have a DS1074z, and I need to maybe check some filter responses, and maybe look at RFI or such stuff, or even look for harmonics on a transmitter.I have almost every piece of gear I ever have told myself I needed, except for an SA because they are soooo expensive compared to most other gear.So, for a hobbyist can this replace the need for a SA for mostly simple stuff when combined with a good signal generator, and a DS10xxZ scope?

content: Quote from: nixfu on December 21, 2014, 07:09:32 amUp to a point: yes. If you look at my comparison between the DSA815 and the FFT analysis you can see that up to say 3 MHz and -50dBm they are almost exactly the same. But further down in amplitude they begin to differ somewhat.So ithinkthat is useable as a SA substitute to possibly a few tens of MHz (remember the scope's BW is only 100 MHz and de sampling rate "only" 1GSa/s). And signals below say -50 dBm are also under suspicion. The scope's AD converters are only 8 bits, and by massively oversampling (say 12 to 25 MPts) you can up the dynamic range to possibly a practical 12 bits (I'm guessing here but the -70 dBm noisefloor of the FFT's seem to suggest this).A real SA goes to at least 1.5 GHz (as my DSA815) and has a much larger dynamic range. the DANL is -130 dBm for the 815....

content: Quote from: AlessandroAU on December 21, 2014, 02:13:26 pmYes theoretically. But -130 dBm starting from a cheap scope with an 8 bits ADC?.The scope itself is 8 bits, so almost 50 dB dynamic range. To get to 130 dB you would have to get 200 Mpts (80 dB = 10 log (200x10^6 /2). Perfectly doable.But... Using these formulas, with 24 MPts (see screenshots below) the FFT would add 10 log ((24 x 10^6)/2) = - 71 dB!If all were perfect I would expect the noisefloor to be at -50-71 = -120 dB. I only see -80 (also at 200 MHz and there I would not expect to see any "real" signal out of the scope). So there seems to be 40 dB missing somewhere. I am no expert on FFT (calculations) so I do not have the answer to this puzzle.Also if you look at the screenshots below there is a significant discrepancy after say 5 MHz. The FFT (with 24 MPts) shows peaks that are not there (according to the DSA815).So the FFT is certainly usable as a substitute for an SA, but up to a point (obviously in frequency, but also in amplitude. Although I do not know how to discern where the useability ends...)Rigol DSA815:24 Mpts FFT from DS1074Z:

content: Fair enough the dynamic range is not that high, but its definitely possible to have a noise floor at -130ish with 24mpoints (by zooming in). However I concede that the best dynamic range appears to be around 105dBm, which is still very good.Also, just to show that is possible to take measurements exceeding 8 bits limit; Look at image 3, the scope is set to 5v/div or 40v max range. A 10mv pk-p signal is applied.This is 20*log10(0.01/40) = -72db below full scale, a full 22db or so below the 8 bit resolution limit. Even though the waveform looks like barely like anything, thanks to the mathematics of the Fourier transform this signal is still measurable. Very neat!Edit:The tektronix MDO series also only uses an 8bit adc internally but has a DANL of -130dbm from 50khz to 5mhz (http://www.tek.com/datasheet/mdo4000/mdo4000b-series-datasheet-0) so it is definitely possible approach this kinda of performance with 8 bits.also see:https://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=22&ved=0CC4QFjABOBQ&url=http%3A%2F%2Fwww.tek.com%2Fdl%2F48W-28882-2%252520%252520%252520MDO%252520Performance%252520WP_.pdf&ei=p_2YVOHwJcLZ8gWIsoKABg&usg=AFQjCNHaLpRkqk9Fxl4CPInDNz58hWFfLQ&sig2=vefpuXdZKo0KQWZVw9PI1g&bvm=bv.82001339,d.dGc&cad=rjaJust wanted to make people aware of this fact! I would trust the scope for use as an SA up to its bandwidth of 100MHz personally.

In the Realtime Capture tab, I can select channels, I can see a waveform (but it says "Input is invalid!" on the scope), if I change the scales on the scope, the graphs change. On Long Memory Capture, changing the # of points gets reflected on the scope (albeit with the issues previously described). When I hit Capture, the scope Stops, I get Input is invalid, and nothing gets displayed.

I can't do a continuous sample and get a waveform - scope just displays input is invalid, changing the scope scales has no effect on the charts, I can't get a screenshot. And when I exit, I get a dialog box saying Resetting VI: Rigol_Capture.vi, which I can only get rid of by killing the process.So, for me, 2.2.3 is broken compared to 2.2.1

Also removed a command from realtime mode, prehaps it will work now.Also added a manual model override function. -so if you were using tcpip in version 2.2.1 it should work now provided you set the model. Actually I had no idea labview automatically handles VISA over TCPIP like that. So that's a winV2.2.3.1http://s000.tinyupload.com/?file_id=22255824192654410391

In other tabs the program just freezes and I have to kill via Windows Task Manager2.2 worked at least somewhat, I can make screenshots, in Real Time Capture it displays a static picture of waveform and FFT (no real time update), but in Long memory Capture just displays a straight line in Waveform window.

content: Quote from: pa3bca on December 24, 2014, 09:36:44 amThis is weird. Here is what I have compared to yours:- I tried starting in Long Memory Capture and it worked just once, subsequent capture does not work displaying just the blank waveform/FFT windows.- If I then switch to Realtime waveform, I can capture static waveform and its FFT, no real time update. Every time I cycle the capture button it grabs a static picture, and the scope screen flickers and says "Invalid data"- If I then switch to Screenshot Capture, I can capture screens no problem each time I press the capture buttonI also noticed in Real Time capture the FFT displays different spectrum depending on the timescale, which makes me think it is incorrectly calculated or the waveform data it is using is invalid. I have attached 3 screenshots of a same 100MHz signal with different timescale, you can see they all show different FFT data.

content: Quote from: Bud on December 24, 2014, 04:48:55 pmWhen the number of samples is fixed and the sample rate changes the FFT spectrum changes with timescale. The FFT is a compromise between upper frequency limit and spectral resolution. Especially since here we are limited by the number of points in the display buffer (hence the point of the long capture feature). The graphs looks fine, the fundamental frequency of 100MHz appears to be correctly identified in all cases, which means the scope is downloading the waveform and its info properly.The sub-harmonic in the 3rd image is caused by one of the higher harmonics being aliased back into the 1st nyquist zone. (Due to the jitter issue)

(I'm on 4) The reason I ask is that it is very unusual that screenshot capture does not work for you. The screenshot sub VI I have implemented comes directly from rigol's examples available on their documents page for the ds1000z series scopes.I have found it even worked on my rigol signal generator. Anyway have you considered updating your firmware?, I think it could possibly solve some of the problems you're having. There should be no reason the program behaves differently for you if we have the same series scope.

content: DS2072, HW v2.0, FW 00.03.01As was previously posted, must set "Manual Model Override" to DS2000 before attempting to display any waveforms. If set later (or left in Auto), lots of unexpected problems occur including program lockup. Also, Long Memory Capture "Number of Points" drop down does not get set to DS2000 choices (stays in DS1000 mode until program restart and Manual Model Override gets properly set first).Cannot change channel settings in Realtime Capture while Cont. Sampling is enabled. Sometimes works but newly enabled channel does not get actual waveform until Cont. Sampling button is cycled off then on. Sometimes locks up program requiring task manager kill then restart.Long Memory Capture "Number of Points" drop down does not synchronize properly -- have to select value twice before the scope and the program's number of points become synchronized. Also, the "Number of Points" drop down does not synchronize to the proper choices when channels are disabled or enabled on the scope itself.Once the "Number of Points" drop down is properly set and synchronized with the scope, the Long Memory Capture only works properly with single chunk scans (14k and 140K point counts). Take a look at the "Data Points" and "Downloading Chunks" fields in the attached screen shots. Ignore the Model and Manual Model Override fields in these images. I changed the connection type to LPT1 after each scan to keep the scope serial number private.

content: This has the potential to be a great tool. I had a play around with it last night and apart from the function errors that kept showing up on the scope (DS1054z 100mhz) it ran great. I did not have any crashes in the 3 hours that I was using it. I did find a few layout errors and also would be great if it was resizable and auto scale the windows inside the main screen.Keep up the great work.
