Guidelines for Operation
Changing HP-IB Units. Use the UNITs command to change the HP-IB Units
setting for selected measurement or instrument setup fields. Only the HP-IB units
for power, relative level, and frequency error can be changed. Table 8 lists the
measurement and instrument setup fields which have changeable HP-IB Units.
For example, the following BASIC language program statements change the
HP-IB Units for the
TX Power measurement from W to dBm:
OUTPUT 714;"MEAS:RFR:POW:UNIT DBM"
