·
The <channel> parameter must specify a single channel.
·
For the VT1536A Isolated Digital I/O SCP, INP:THR:LEV? returns a numeric
value which is one of 5, 12, 24, 48, or 0 (zero) where zero means that the channel
is configured as an output and non-zero values indicate the input threshold in
volts.
Note If an invalid switch combination is set on a VT1536A, INP:THR:LEV? will NOT
return a value and will generate the error 3105 “Invalid SCP switch setting”. This
error will also be generated when *RST is executed. Channels associated with this
error will behave as input channels with unknown threshold levels.
·
Usage: To query the threshold level on the second channel at SCP position 2
send:
INP:THR:LEV? (@117) query 2nd chan on SCP pos. 2
