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 in
9-1 on page

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 in

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.
