OUT Signal Frequency

[pascal.verdet]

Hi,

Does anyone know or can measure the frequency of the signal / OUT (Con 62) on the analog output modules 82E42 (VCA Version) or 82E357 (Ultimation view)?

The both board are in Computer Rack.

Many thanks,
Cheers,
Pascal

I tried measure Ultimation version. Pulled card out with extender and left ribbons unconnected and measured from IC7 pin 10. I eas able to see some pulse but had quite lot of noise thus couldn't check frequency. Should I trig my scope from some soecific point or something?

Thanks Paavo,

The nearest 0V point is IC7 Pin 7, may be not easy to connect ...
Otherwise, I don't remember there is a 0V Test Point on the board, however the point 2 of LK2 jumper (Open) is 0V

Thanks for your help
