Meas UNCAL Error
Meas UNCAL appears in the lower-left corner of the screen when the FieldFox
can NOT display accurate measurement results with the current settings.
Usually, the part of the trace that is inaccurate is shown at –200 dB.
The following situation can produce Meas UNCAL:
When the ResBW/VBW ratio exceeds 10,000, causing the VBW filter to reach
the maximum capacity for averaging.
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 75.

The following Channel Measurements are offered in SA Mode:
Channel Power ..................................................... 107
Occupied Bandwidth ........................................... 109
Adjacent Channel Power Ratio ......................... 110
The following four sections (Radio Standards and Channel Measurements,

Measurements.
