Status Panel (Acp) - Anritsu Field Master Measurement Manual

Making Spectrum Analyzer Measurements
Adjacent channel power is a constant measurement; after it is turned on, it remains on until a different
measurement is selected or the sweep is paused. ACP is calculated at the end of each sweep.

STATUS PANEL (ACP)

Below is the status panel with the corresponding minimized status panel icons for adjacent channel power
measurement.

Spectrum Analyzer MG
REF LEVEL: Sets the reference level of the top graticule line in the selected units.
If the reference level offset is not zero, OFFSET REF LEVEL is displayed at this
location.
Refer to Section 3-4 "Setting Amplitude Parameters" on page
SCALE/DIV: Sets the graticule scale/division for log-based units. This setting does
not apply to linear units.
REF LEVEL OFFSET: Sets the reference level offset in dB units. This setting can
compensate for the presence of external input attenuation or gain.
FREQ OFFSET: Accounts for frequency conversions outside of the analyzer.
Refer to Section 3-3 "Setting Frequency Parameters" on page
ATTEN LEVEL: When auto attenuation is off, sets input attenuation.
PRE AMP: Toggles the low-noise front-end preamplifier on or off. Refer to
Section 3-4 "Setting Amplitude Parameters" on page
TRACES/CURSORS: Displays the current status of up to six traces or cursors in a
quick-view summary. When the measurement view is set to Normal (Spectrum),
trace information is displayed in this area. When the measurement view is set to
Spectrogram, cursor information is displayed in this area. Cursors are available in
the Spectrum measurement with the Spectrogram view selected.
The summary information includes the trace or cursor number, type, mode, and
detector type. The active trace will show a highlighted background with the mode
and detector type restated under the table. In Spectrogram, a reference trace (T0)
will show you the settings of the trace used to fill the spectrogram. The reference
trace settings are applied to all traces and cursors while in Spectrogram view.
Pressing a trace or cursor in the summary panel activates the pressed trace or
cursor and opens the TRACE menu, allowing you to select and set up an individual
trace or cursor as desired. Refer to
on page 3-19.
SWEEP: Toggles the current sweep setting between continuously or sweep once.
Refer to Section 3-8 "Setting Sweep Parameters" on page
FREQ REFERENCE: Indicates the current frequency reference source of Internal
High Accuracy (used after GPS has lost sync, but while the internal clock still has
good GPS reference), Internal Standard Accuracy, External, or GPS Hi Accuracy
(requires GPS). The instrument automatically selects the frequency reference in the
following order of priority: external, GPS, then the internal time base.
