Hi.
Got me one with a broken display which is now fixed. Tried it both in loopback and with external signal.
The pictures shows some artifacts that I believe shows some error with at least the ch 1 input board. I haven't had time to test ch 2. Neigther have I tried to calibrate anything yet.
Another possibility is operator error and infact it works perfectly well. I might be stressing it as I wanted to see if there is anything below the noisefloor
...
This one is showing an external 1kHz 10mV sine signal. You can see the spikes below the noisefloor.
These are randomly popping up (well, rather down
) everywhere in the span.
Regards

Sorry, I were unable to attach two pictures in the same post as I were unable to differentiate them by name so both uploaded as image.jpg and the second one overwrote the first. Hence this second post...
This shows an internal source 2kHz sine signal. Here the spikes are dancing above the noisefloor...
