Thanks @attila! I’ll give it a go today :)

Hi @Walter76
It looks like some AC coupling going on 2+ Since 2- is fine we can rule out wiring problem.
It may be a cold soldered resistor on the 2+ input:

How does 2+ behave at high range, having Scope Channel 2 Range above 500mV/div or in Network Analyzer Amplitude above 2.5V ?

I see! 🙌 Thank you very much, @attila! That works beautifully, AND I learned about the tooltips! Neat!
Thanks again

Hi @Arno
For warranty and replacement contact the support.digilent @ ni.com specifying the Date of Purchase, Seller and Purchase Order/ Web order Number.

Hi @attila

I was able to figure things out because you helped me.
I appreciate your support.

Hi @attila
I don't know that we need to set the frequency, I understand the problem ! Thank you !!

Hi @nurber3

Hi @Xavier Jiang
You probably used Record mode to capture multiple samples, which uses data streaming and has limited rate, ~3MHz for AD2 and ~10MSps for AD3.

Thank's a lot for the quick response!

Ah, yes, thanks - without "_" in the variable name the auto complete is recognized. The "Acq" value from the Measurements table  is called "count".

Thank you!

Hi @ionica
The Lock-in is only available in the WaveForms application Scope interface, it is a software feature.

Hi @jabitti
For hFE select Measure: Ic/Ib

That worked fabulously. I'm getting the expected results, and I understand how the software works better. Thanks @attila!

Hi @yusuke_Adv

Hi @Musicsteve
The dropdown options should show up on click.
What OS browser are you using?
The download links are also available here:
https://digilent.com/reference/software/waveforms/waveforms-3/change-logs/3-20-1
or the latest beta version here:
 

Yes. I am using the Sync mode in Logic Analyzer. Your advice is very helpful.
After reading the sample scripts you mentioned(DigitalIn_Sync.py), most of my questions have been answered.
I will give it a try.

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!

Hi @attila,
Thanks for the reply. Updating to a newer OS would be my last resort, but if you think nothing can be done on CentOS7, I'll try to upgrade.

Hi @cdupuis
Fixed in the latest version:
Thank you for the observation.

Hi @nurber3
The flywires are UL1007 24AWG OD1.45

Hi @attila
That is excellent!
After clicking "Check for Updated", I downloaded Waveforms 3.20.1, and indeed the problem has been fixed.
The traces now looks like this when zoomed out:

Thank you so much for the quick response!

@attila
Thanks for the suggestion, but I had already uninstalled it on the Windows 7 machine. Looking for a Windows 10 machine to try. 
They do not list any system requirements, but I notice an earlier version of release notes say Windows 7 no longer supported.

Thanks for answering, portability with USB power a must for me and I believe ADPx000 are all powered with external power supply.
