SIGNALlab 250-12 attenuator

Post by KSY » Thu Mar 31, 2022 3:54 am


I want to use SIGNALlab 250-12 cause of its' sampling rate. However, 250-12 does not seem to have HV-LV jumper. According to official documentation, it seems to change automatically, then is it OK to start FPGA programming without considering the input voltage? (Of course, the input voltage will not exceed 20V) Or, if I should consider, how can I control attenuator at the software level?

Thanks for the help

AFAIK, STEM250 has a relay that switches automatically with selected oscilloscope display voltage scale, not unlike purpose built scopes.
