Real-Time Spectrum Analyzer (RTSA) Measurement Guide : Real-Time Spectrum Analyzer (Option 199) Overview : Status Panel (RTSA)
 
Status Panel (RTSA)
The status panels and features illustrated in this section are unique to the real-time spectrum analyzer and to the selected measurement and view. Below is the RTSA status panel that covers RF Spectrum and spectrogram views, in addition to audio AM/FM and interference measurements (selected via MEASURE > MEASUREMENT menu).

Pressing editable parameters opens the associated menu with a keypad that allows you to conveniently change the parameter value. These are the same settings found in the right side menus.
POI
Probability of Intercept (POI) is the minimum signal duration that the analyzer can detect at full amplitude with 100% probability.
MIN DETECT
The minimum detection is the minimum signal duration that the analyzer can detect.
REF LEVEL
Sets the reference level of the top graticule line. If the reference level offset is not zero, OFFSET REF LEVEL is displayed at this location.
SCALE/DIV
Sets the graticule scale/division for log-based units.
REF LEVEL OFFSET
Compensates for the presence of external input attenuation or gain.
FREQ OFFSET
Accounts for frequency conversions outside of the analyzer. Refer to Setting Frequency Parameters.
ATTEN LEVEL
When auto attenuation is off, sets input attenuation.
PRE AMP
Toggles the low-noise front-end preamplifier on or off. Refer to Setting Amplitude Parameters.
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 RF 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 only available in the RTSA 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. It allows you to select and set up an individual trace or cursor as desired. Refer to Setting Trace and Cursor Parameters.
SWEEP
Toggles the current sweep setting between continuously or sweep once. Refer to Setting Sweep Parameters.
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 GNSS (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.
