Output RF Spectrum, Trace View (Option 006 Only)

This view displays output RF spectrum power spectral density (at the Freq Offset

setting) versus time.

The Agilent 8922M/S uses a 3-pole synchronously tuned ﬁlter to make Output

RF Spectrum measurements rather than a 5-pole ﬁlter as speciﬁed in the GSM

recommendations. Refer to Section titled “Output RF Spectrum Measurements

Using a 3-Pole Synchronously Tuned Measurement Filter” in Chapter 2.

1. Amplitude This is a copy of the RF Analyzer Amplitude ﬁeld. This is the amplitude to be

assumed at the selected input port.

Range RF IN/OUT: −27.9 to +41.0 dBm. AUX RF IN: −58.0 to +20.0

dBm.
