Much appreciated.Thanks,Ron

content: Welcome to the wonderful world of Digital Oscilloscopes,If you have too long a time/div setting,your sample rate may be too low to reproduce the RF frequencies correctly.Try reducing your transmitted (suppressed carrier) frequency,say 3.5MHz instead of,maybe,14 MHz.

content: My TEK TDS430A has Envelope mode to show this sort of thing. Works decently as long as the displayed signal isn't too close to the noise. You can see some of my results showing AM modulation envelope with the TDS430A in envelope mode athttp://www.cliftonlaboratories.com/am_modulation.htm

content: This is one of the applications where the signal processing performance of the z-axis of a DSO is weighed. Maybe it is no use for OP but at least Agilents perform quite well even for this kind of applications (I believe OP means X-Y mode where RF output is fed to X and modulating signal into Y-channel).Regards,Janne

content: You may also want to try changing the triggering to "Line" so that there's a consistent trigger. Part of the jerkiness could be due to the scope switching between "triggered" and an "auto-trigger".There are some things that an old analog scope is just naturally better at doing than a DSO.

I own the same model as the one you're referring to but it was a bit more expensive because it included a battery.If you choose Rigol, don't go for the 100MHz model, get the Rigol DS1052E and hack it.

timestamp: September 24, 2017, 02:40:13 am
content: I'm learning how to use my DS1000Z scope with the Ds6k board. The DS6K has a Rare Abnormal Signal which is a 1MHz square wave with a narrow pulse of < 5ns every 100ms. The instruction from the manual states:"Set the trigger type to “Edge”, the trigger mode to “Single”, the horizontal time base to 5ns, the waveform capture rate to 180kHz, the memory depth to “Auto”. Set the persistence time to 20s and the capture result of abnormal signal is as shown in the figure below."I'm following the manual for the demo board and I am not able to catch the 5ns pulse. I can set the waveform capture rate and the persistance time is either 10 sec. or infinite. Any suggestions on how to set up a DS1000Z to catch it?Thanks,S18

I setup a pass/fail mask around the 1MHz square wave and turn on StopOnFail. On the first failure, the pulse is captured.The last time I touched/used an O-scope was back in the days of CRT. The advances in these devices are just amazing.S18

I need the VSWR option as I biult my own VSWR bridge and it's considerably more comprehensive than the VB1020 offering. Problem is the licence is the deal breaker. Since the VB1020 is obsolete now the software has leapt to more than half the price of the scope and quite frankly it sucks. I know there are programs for the DDA832 but I'm old school and won't upgrade my trusty 1030a. Help very much appreciated

I hope the person who coded the original generator may find time to code the DSA1030a-TG as I really only need to run a few SWR tests, if they work with my homebrew VSWR Bridge then I would gladly take the plunge, I need to try before I buy.

Rigol MSO5074 - issue with Pass Fail analysis and WebControl - Page 1
Forum section: electronics / beginners

timestamp: February 17, 2025, 06:31:10 pm
content: Hi,I've been playing with my MSO5074 (bought new, then unlocked according to the information in this forum) and the Batronix MSO Demoboard. Everything runs smoothly except the attempt to use the PassFail analysis to count the occasional glitches in a 10kHz sine wave (lection 2.11 from the manual).What I did: Connect the demo board via BNC to channel 1. Edge trigger and adjust scaling such that 5 periods nicely fill the screen. Run a single measurement to freeze a nominal waveform. Go to PassFail, create a mask off the screen using default settings, acivate the information window, switch to continuous measurement and hit the play button. I can see how the glitches are plotted against the mask but all three counters remain at zero. I also checked other channels, played with the acquisition mode (normal, high-res), different vertical and horizontal scaling but nothing worked.Now comes the funny part: I then switched the scope off, took a break, switched it on again, activated PF analysis just as described above and it worked straight away! I was so excited that I decided to be bold: I stopped the PF analysis, went to the options, activated "beeper" as Err Action, started the PF analysis again... and the counter would not count. A few more attempts later and the feeling of stupidness is increasing. I'm at a loss here.This directly leads me to the next issue. In order to create screenshots to illustrate the PF issue I wanted to give the WebControl feature a go. I know that I can grab screenshots within the scope, but again I wanted to be bold. The scope is connected via DHCP and the main status page displays all the good stuff (including firmware 00.01.03.03.00 if that matters), but once I go to the WebControl tab it asks for a user & password. According to the scope's internal ntework info page this should be admin/rigol but that is not accepted in WebControl. I then found various hints such as "empty user"/111111 but none of them worked. How can I access WebControl? I tried Chrome and Firefox on MacOS and Chromium from my Pi.CheersTorsten

Wait, they do by offering lower performing models which might be more in line with Schools and hobbyists.Am I wrong ?Now that you are making me think...thanks...It seems more to the point that each model is aimed at different markets, so it's up to the user to chose a more prosumer model or not...so in a nutshell, the Ds1054 is aimed at an entry level and the DP832 isn't.Thanks to all !

content: So I have recently bought RIGOL DS1102 oscilloscope. It gives a view of maximum 10 seconds at the widest horizontal setting. However at this resolution it takes approximately a minute just to plot the samples captured.I am playing around with piezo buzzer these days and was curious to see how voltage fluctuates as you touch it. Does anybody know a way in which the scope would reduce the sampling rate significantly where one might see in real time how the voltage is fluctuating? As in those ECG machines where a meteor type line is running constantly and it goes up and down as the heart beats.Thanks

content: I am tuning 3 Sinclair pass notch cavities at 146.37MHz using the Rigol rsa5065N with tracking generator. The cavities have a 120dB notch. I also have a Rohde&Schwarz SML 02 signal generator. I first used thee signal generator to tune the pass and notch frequencies. I could easily see the notch signal about 10dB above the noise floor with 0 dBm feeding the cavities.Now I turned on the tracking generator , also set at 0dBm signal level. The display jumped up to -100dBm as I sweep the notch at 100khz span and the signal out of range shows on the screen. At this point I hooked up my tiny spectrum analyzer to the tracking generator directly through a 20 db attenuator and noticed and notices spikes randomly appearing in the 2MHz span along withe the desired sweep signal. I set the span to zero and the spikes moved around but the 146.37 MHz carrier was clean and stable otherwise.It looks like the tracking generator has a problem. I experienced the same phenomenon when I tuned some pass reject cavities for 222.32MHz repeater receiver. Thank you 73…FrankI contacted Rigol sent my unit back to them and it has the same issue. Could someone with an rsa5500 take a look at your tracking generator signal.

content: Quote from: m3vuv on April 27, 2022, 11:44:49 pmYou are misunderstanding the way the menus/multi-function knob work. Having brought up a menu using any of the buttons that normally do so (Utility in this case), you select between the items using the buttons to the right of the screen. If any of those menu items have sub items you can use the multi-function button to select between them/set a numeric value. The circular arrow above the multi-function button should light up when you can use it in this way. By default, it will just alter the screen brightness, even if you are displaying a menu but you have not selected an option where it will be used for something else (i.e. the circular arrow is not lit).So, in your case you want 'Utility', bottom button until 'System Info' is shown, button next to 'System Info'. That will bring up the System Info screen. Then you can enter CH1, CH1, CH2, CH2, MATH.

For temporary stuff I use the cheap "One Hung Low" stuff, but they really are garbage (don't crimp as securely, are super thin and flexible, are much much more likely to snap off or fail). For anything permanent or important (like mains level voltage) I usually get Anchor brand or equivalent quality. They are eye-wateringly expensive, but they are far and away better quality plus they are corrosion resistant since they are made for marine applications. TE makes some great stuff too, check out their "Diamond Grip" line. I believe it is mil-spec.

One classic homework is to proof/derive the transformer dimensioning equations, so you don't forget them.The ripple voltage for a bridge rectifier circuit isWithIoutthe output current through the output loadRL, smoothing capacitorC, AC frequencyfand internal transformer resistanceRi.If you then start to simplify by choosing/assuming a transformer where you haveyou getYou specify a maximum ripple you can accept, and solve that equation for C.If you are into simulation you can then use the values as a start for a simulation.In reality you use a few more equations to calculate required transformer properties (which I am too lazy to look up), which in turn requires to solve a non-linear equation system, which you typically do via a relatively simple iteration in the particular case. And again you can plug the result of the iteration or just an initial ballpark estimate into a simulator if you like.

content: Good questions, but there are no concise answers...There are standards for testing EMC (including conducted and radiated emissions). For example, I think a phone charger would be CISPR 22 and FCC part 15. These standards describe detailed methodologies for quantifying emissions, and permissible limits on those emissions. These methods don't look at things in terms of "ripple" and "noise". The test equipment required is fairly sophisticated (especially for radiated emissions), far beyond the reach of hobbyists and small companies.However these standards care about emissions into the mains via conduction or the air via radiation. They don't care at all about what the output voltage of the DUT looks like. I don't think standards exist for output voltage, that's entirely application dependent.

If a value is published as a percentage is oh I dunno 1% acceptable, 2%, 5% whatever.Now I know this depends on the main circuit so I am assuming something like a general purpose MCU doing some switching, reading from a Bus (I2c,SPI, UART) and driving some LEDs, sort off thing NOT a precision instrumentation amplifier trying to detect a Neutrino from the Big Bang!Thanks

OTOH if it has a 10 bit ADC converter with either the input or the reference relative to the supply rails, even 0.01% ripple is likely to be objectionable.Also you should distinguish between double line frequency ripple from a conventional linear PSU and high frequency ripple from a switching supply which IMHO is more likely to cause issues (at any particular peak to peak amplitude) due to greater capacitive coupling to sensitive nodes.
