I use a new 2204A picoscope and the FRA4 0.5.3b version.
By select device I get this:
PS200 DV 037/057 available
the software works, but I get no signal at the function generator, so the plot result is not useful.
Thanks for support,

thanks for your support.
Yes, I have an other scope, a Hantek DSO5102B 100MHz. And I cannot find a signal at the AWG Port.
When I use the picoscope software, the AWG works, can see it by the picoscope and by the Hantek.
If I test a simple RC filter, the plot result is only a chaos signal between -90db and -70db or something other chaos.
I think, the result is with so less db, because there is nothing to messure when the AWG is not working.
If it is helpfull, I can load a screen of a plot.
Thanks and best regards,

did you tried already to measure the feedback loop stability of a switching power supply?

Because I'm quite new to this topic I wanted to ask you, if the impedance of your injection transformer VB-1BB with 75 Ohms is no problem, because all the signal generators and oscilloscopes have 50 Ohm outputs/inputs? Is there a need of an additional adaption network?
Thank you very much in advance!
with version 0.5.3b and the 5244B on double-head USB cable i got following error:
Error: Unable to initialize device with serial number CZ108/032
