Channel Measurements - Agilent Technologies N9913A User Manual

Old Data Indicator (*)
In SA mode, when the current trace does not exactly match the annotation that is
on the screen, an asterisk is displayed in the upper-right corner of the screen
graticule area. This would occur, for example, when the Res BW setting is
changed while in sweep Hold mode. The annotation is changed immediately, but
the trace is not updated until the next sweep occurs. Therefore, the current data
trace does not match the screen annotation. See the asterisk on page 81.

Channel Measurements

The following Channel Measurements are offered in SA Mode:
Channel Power ..................................................... 115
Occupied Bandwidth ........................................... 117
Adjacent Channel Power Ratio ......................... 118
The following four sections (Radio Standards and Channel Measurements,
Measurement Preset, Averaging, and Traces) are relevant for ALL Channel
Measurements.
Radio Standards and Channel Measurements
To tune the frequency range of any of the Channel Measurements using channels
instead of frequency, first select a Radio Standard, then select Units = CHAN.
Learn how to select a Radio Standard and channels on page 84.
When you first select a Radio Standard, then select a Channel Measurement:
 With Units = FREQ selected, the center frequency and span will ALWAYS
 With Units = CHAN selected, the FieldFox chooses either the uplink or
When you first select a Channel Measurement, then select a Radio Standard,
the BW, Offset, RRC, Integration BW, and Span settings are changed to those of
the standard. In addition, Res BW can also change when set to 'Auto(couple)'.
However, center frequency is NOT changed unless you first select Units = CHAN.
Measurement Preset
Measurement Preset allows you to easily reset any of the channel measurements
to its default settings. The Center Frequency, Preamp ON|OFF, RF Attenuation,
Markers, Limits, and Radio Standard settings are NOT reset.
How to select Measurement Preset:
 Press Preset then

downlink band, and displays that range of frequencies. You can then tune
within that Standard using Start CHAN, Stop CHAN, or Center CHAN. The X-
axis annotation indicates the frequency range.
