CALC:STAT ON ’ Enable math calculation.
ROUT:CLOS (@101) ’ Close channel 101.
CALC:DATA? ’ Read mX+b result for channel 101.
ROUT:CLOS (@102) ’ Close channel 102.
CALC:DATA? ’ Read mX+b result for channel 102.
Example #2 — The following command sequence configures channels 101 through 110
of the Model 7700 to perform the percent calculation when they are scanned.
NOTE The following example can be run from the KE2700 Instrument Driver using the
