UNIT Subsystem
The UNIT command subsystem:
– Sets power measurement units to dBm or Watts.
– Sets measurement ratio units to dB or % (linear).
Both UNIT commands have a numeric suffix which determines which window/
measurement is set:
– UNIT1: units are set for the upper window/upper measurement.
– UNIT2: units are set for the lower window/upper measurement.
– UNIT3: units are set for the upper window/lower measurement.
– UNIT4: units are set for the lower window/lower measurement.
The following commands are described in this section:

The UNIT:POWer and UNIT:POWer:RATio commands are coupled as follows:
– If UNIT:POWer is set to dBm then UNIT:POWer:RATio is dB.
– If UNIT:POWer is set to W then UNIT:POWer:RATio is %.
