  1. Eclypse works well also, thanks again. I also like the separate pulldowns for wavegen and filter channels, those could get quite tall when stacked up!
  2. Attila, I finally got a chance to download and try the above beta version 3.20.27 (2023-08-18), and looks like the crashes are fixed when trying to alter 65536 sample waveforms on my ADP3450. I'll verify on my Eclypse Z7 also, but so far looks good! Thanks. JimR2
  3. Thanks for the detail, I appreciate it. Regards, JimR2
  4. This worked, thanks Attila, I guess the message showing the "buffer size is 65536 samples" despite setting to 32768, is just a warning tht you are not using the entire hardware buffer? I'm really surprised I never saw this before? Has this always been a limitation with Waveforms? Thanks, JimR2
  5. I have an Eclypse with a Zmod config as seen in the pic#1, ZMODA=AWG, and ZMODB = Digitizer What I've found is that when trying to create a custom wavegen waveform, say a 2-tone stimulus by using a sine Func, and then altering it with a 2 cycle sine Func, right after you hit Generate (for 2 cycle sine) and then OK, which should then combine the 2 sine waves, Waveforms crashes. So basically I get to the point shown in Pic#2, and after I hit OK, Waveforms shuts down unexpectedly. After crash, I sometimes have to power off/on the eclypse to get waveforms to connect to it again after a crash. I've done the exact same operation on my adp5250, and it works. I have not confirmed on any other device combination but can try if you need me to (have AD2, AD3 and ADP3450 I can try). I'm still using version 3.10.10 of Waveforms, from the last bug I submitted, please let me know if there is a new download that should fix this, or if you want me to do any other checking. Regards, JimR2
  6. Thanks guys, sorry haven't checked forum in a while. Looks like my defective Eclypse is out for delivery in Washington, will await replacement! Found a Waveforms bug, using the Eclypse this morning, will put in separate thread. Regards, JimR2
  7. I have a fairly new (purchased Feb or March of 2023) Eclypse Board that recently stopped powering up.I have two Eclypse boards and multiple ZMODs, and the board in question always exhibited an odd behavior, but otherwise functioned well. The fan would appear to rty to be starting, but wouldn't start spinning. If I gave it a gentle nudge, it would start. Now it simply won't even light the LED stack when powered up. Is there any diagnostic steps recommended? I plugged my other Eclypse into the same power supply, and it works fine. I also swapped to two Zmods that were in the non-functioning board to the spare, and they seem to also work. Also, jumper configurations are all same, and swapped sim card, and is functional in other board, though thouse shouldn't be keeping the indicator light from coming on. Also couldn't find a warrenty period on these listed anywhere, if you could provide that info, in case I need to return. Thanks, JimR2
  8. There appears to be a bug when using markers in the spectrum analyzer. Attached is a snippet from a 158MHz tone sampled at 1GHz on my ADP5250. It appears the frequency is limited to 100MHz for marking, but the magnitude follows the signal strength, so it appear to be detecting the correct peak tone? Also attached below is the Waveforms version I'm using. Regards, JimR2
  9. Atilla, Thanks for the information. I just downloaded the latest Beta you recommended, and that fixed the ADP3450 Dual DPS3340 issue I was seeing. Thanks! Regards, JimR2
  10. Hi, I recently downloaded a new version of Waveforms (see pic1), and noticed a relatively new feature Select + Dual. A common use case for me is to select my ADP3450 + DPS3340 (see pic2), which has always worked fine before. Now it appears if I try and use the Scope, or scope with DiscoveryPS, I get an error (see pic3) that constantly repeats. Sometime so rapidly, I have to kill the Waveforms task. Also have noticed that when I do this, 8 channels show up on the scope, 4 osc channels, and 4 supply channels. Playing around a little, it appears as if I were to turn on the spectrum analyzer before the scope, this change how the channels appear in the scope, and everything works fine? See pic4, where I have DiscoveryPS, wavegen, spectrum analyzer open (since I ran before opening scope), and eventually scope in upper left corner which behaves as normal. So seems there is a workaround for now, but probably something that should be looked into. I also played around with the select + 2 to combine two identical devices (2 AD2's), very cool feature! Hoping it works with Digital Discovery also, was thinking about buying a 2nd one. Thanks, let me know if you have any questions or things you'd like me to try, Regards, JimR2
  11. So I've repeated my measurements now that I have compression turned off, and am seeing what you see, but in LabView. I think having compression turned on, it was only outputting the state changes, and gave me the impression the clk0 was doing something. I also can configure the trig for dio15, and it behaves accordingly (waits if no trigger present), whereas now when I configure it as mso/clk0, it triggers all the time? Could have sworn I sanity checked that few days ago? Now I'm not so convinced in my finding. Bummer! Jim
  12. Thanks Atilla, So if I understand your post correctly, you've seen no evidence of clk0/1 effective as a trigger in Wafeforms, correct? I'm a little unclear what you mean by "STATE MODE", can you clarify. I've been playing around a little more with LabView, been a few years since I dabbled with this software tool. I'm more of a Matlab guy, but also have become very fond of the scripting ability in your instruments. I've been poking into the Waveforms VI's to overcome limitations in the "RDWF MSO Read.vi". I realized in the sample size seems to be hadcoded to 16384, and Binary to Waveform conversion VI had compression turned on (see snippet), so the data I showed above may not have been ALL the samples that were occuring. It explains some things, but need to repeat with these limitations overcome, as well as trying to output a BCD value to make sure I know what I'm getting is truly due to the clk0 or clk1. Regards, JimR2
  13. Hi Attila, I think I've been able to access the clk0/1 pins of the LA on the ADP5250! I was unable to obtain the VB VI's for the VB8012, so I've been playing with the Digilent provided VI's instead. I noticed when selecting "Description and Tip" on the "Trigger Source" for the "DWF MSO Configure Digital Edge Trigger.vi", that it showed this, With a little playing around, I built a simple LA VI using the Labview Waveforms VI's, and was able to verify that the clk0 on the LA port is accessible this way AND it can provide the behavior similar to the sync mode in Waveforms! To prove this out, I did the following (many pics to follow)...... I setup my ADP3450 to provide a test stimulus of a walking one's pattern (DIO14:0) to the ADP5250, and DIO15 I configured as a clock. See pic below. Then using a simple VI I cobbled together, was able to config the ADP5250, play around with how the VI controls vs what the ADP5250 is actually setting up for some of these (readbacks showed sample rate is always auto adjusted based on data activity, regardless of settings), as well as dump the captured waveform data to a text file viewing. To see if triggering on DIO15 vs clk0 was any different, The stimulus above I made sure the rising edge of the clock was centered in time with the center of the walking ones' bit. Then performed two captures, with the PGen/LA wiring as: trigger PGen DIO15 = LA DIO15 , LA clk0=gnd The captured data below shows a walking one's, but with each being a sequence of 2@ 1's. This appears to be due to the waveform structure or capture itself (maybe you can shed some light here) all events are captured with a time stamp, so the 2@ 1's for each step of the walk is the event when the walking 1 changes to a high state, and the 2nd is when the DIO15 trigger changes to a high state. Thus time stamping at 50us step for a 10KHz walking one, which only changes every 100us. Then I repeated the capture with the only changes being in the VI below for trigger on clk0, and re-wiring PGen/LA as: trigger PGen DIO15 = LA clk0 , LA DIO15=gnd This showed a different behavior as seen in the data below, where now only a single bit is captured for each walking one, coincident with the clk0 rising edge! So this seems to confirm the clk0 isn't really acting as a trigger (maybe my definition is too confining), but more as a what I would call a "sync clock"?? So these results seem very promising for me for use on my ADC test-bench to replicate the Waveforms "sync mode", and plan to experiment some more to better understand the flexibility Labview may give over Waveforms. Wanted to pass along in case this information is also useful for others, since finding documentation on the VB8012 was going nowhere for me. Kind of wish this was specified in the Hardware specs. Kind of glad I missed the mention of the clk0/1 not being supported by Waveforms, may not have purchased the 5250 to begin with? Now I'm hoping to be able to reliably capture higher data-rate up to 32 bits of data!! We'll see..... Regards, JimR2
