UNIT Subsystem
The UNIT command subsystem is used to set the power meter
measurement units to Watts and % (linear) or dBm and dB (logarithmic).
The numeric suffix of the UNIT program mnemonic in the UNIT commands
refers to a window, that is UNIT1 and UNIT2 represent the upper and
lower windows respectively.
The UNIT:POWer and UNIT:POWer:RATio commands are coupled, that
is, if:
• UNIT:POWer is set to dBm then UNIT:POWer:RATio is dB.
• UNIT:POWer is set to W then UNIT:POWer:RATio is %.
