Is QA Q400 still working?

Hey Guys,

I’m running an old QA Q400 for testing and first measurements on Windows 10.
I’ve downloaded the software for the QA400.
Sadly, it’s not working. During the calibration test he gives me an output voltage but can’t find any input signal.

The picture shows, what it shows to me wenn I’m running a signal in the analyzer. The light on the right channel for signal is going on and off.

Any ideas?

Thanks in advance
Flo

Hi @FlorianErnst, do you see anything coming out of the outputs in any mode of operation?
