Power Meter Remote Operation
Status Reporting
Examples
This example program uses the *OPC? command to determine when the
power meter has finished calibrating.
CAL:AUTO ONCE
*OPC?
MEAS:POW:AC?
This example program, in HP Basic, uses the *OPC command and serial
poll to determine when the power meter has finished calibrating. The
advantage to using this method over the *OPC? command is that the
computer can perform other operations while it is waiting for the power
meter to finish calibrating.
