Hi folks,

hope the question is not too dumb...

I am trying to understand how the scan list exactly works, as we had some issue (could also be hw related...)

scan.create(1001:1010,"dcvolts")

Easy at it is...

how smart is the Keithley 3700A?
  • will it detect stuck relays?
  • will it wait till relays "bouncing" is "finished"?
  • does it really work like "close 1001 --> measure --> open 1001 --> close 1002 --> measure --> open 1002..."?

Thanks in advance!

Depending on the connection rule in use, when moving to next channel in a scan, the opening of prior channel and closing of next can occur simultaneously or can be configured for break before make, etc.

In general the scan is just closing, measure, open/close next channel, measure, etc.

Since a measure function is associated with the scan, the instrument will also manage the backplane relays to connect the switch to the internal DMM.
