Parameter

Description

"Channel" / "Notch"

Channel or notch number

"Channel BW" (auto
mode) / "Integration BW"

Specified channel bandwidth or manually defined integration bandwidth used
as basis for power density calculation in total channel or notch

"Offset"

Frequency offset of notch or integration bandwidth to center frequency

"Power density"

Power measured in channel or notch divided by the "Channel BW"/"Integra-
tion BW" in dBm/Hz

"NPR"

(Notches only:) Ratio of total channel power density to notch power density in
dB

Remote command:

Channel power density, notch power density, power ratio:
