Power Monitor Menu (Option 5)

Selecting POWER MONITOR from the Mode menu causes the soft keys, described below, to be displayed and the corresponding values shown in the message area.

￿UNITS — Toggles between dBm and Watts.

￿REL — Turns relative mode OFF, if currently ON. If relative mode is cur- rently OFF, turns it ON and causes the power level to be measured and saved as the base level. Subsequent measurements are then displayed relative to this saved value. With units of dBm, relative mode displays dBr; with units of Watts, relative mode displays % (percent).

￿OFFSET — Turns Offset OFF, if currently ON. If Offset is currently OFF, turns it ON and opens the Offset parameter for data entry. Press ENTER when data entry is complete.

Offset is the attenuation (in dB) inserted in the line between the DUT and the RF detector. The attenuation is added to the measured input level prior to dis- play.

￿ZERO — Turns Zero OFF, if currently ON. If Zero is currently OFF, this softkey turns it ON and initiates collection of a series of power level samples, which are averaged and saved. This saved value is then subtracted from sub- sequent measurements prior to display.
