Chapter 2 Functions and Operations

SWEEP

Displays the Sweep function soft key menu for the current operating mode.

Sweep Menu Provides for changing the display resolution, single or continuous sweep, and access to the Trace Math functions.

Choosing SWEEP in FREQ or DTF measurement modes causes the soft keys below to be displayed.

￿RESOLUTION — Opens the display to change the resolution. Choose 130, 259, or 517 data points. (In DTF mode, resolution can be adjusted through the DTF-AID table.)

￿SINGLE SWEEP — Toggles the sweep between single sweep and continu- ous sweep. In single sweep mode, each sweep must be activated by the

RUN/HOLD button.

￿TRACE MATH — Opens up the Trace Math functions (trace-memory or trace+memory) for comparison of the real time trace in the display with any of the traces from memory. (Not available in DTF mode.)

￿TRACE OVERLAY — Opens up the Trace Overlay functions menu to allow the current trace to be displayed with a trace in memory overlaid on it. Choose ON or OFF and SELECT TRACE to select the trace from memory to be overlaid.

Choosing SWEEP in SPECTRUM ANALYZER mode causes the soft keys below to be displayed.

￿RBW — Sets the resolution bandwidth so that it is either coupled automati- cally to the span (AUTO) or manually adjustable (MANUAL).

￿VBW — Sets the video bandwidth so that it is either coupled automatically to the span (AUTO) or manually adjustable (MANUAL).

￿MAX HOLD — Displays and holds the maximum responses of the input sig- nal.

￿CONT/SINGLE — Toggles between continuous and single sweep.

￿MEASURE — Activates a menu of measurement related functions. Use the corresponding softkey to select the measurement function.

￿FIELD STRENGTH — Accesses a menu of field strength measurement options.

ON/OFF - Turns field strength measurements on or off.

SELECT ANTENNA - Selects an antenna profile to be used for field strength measurements.

BACK - Returns to the previous menu.

￿OBW — Activates the occupied bandwidth menu. Select either METHOD, % or dBc method of occupied bandwidth measurement. METHOD allows selection of either % of power or dB Down. Selecting % allows entry of the desired % of occupied bandwidth to be measured.

Selecting dBc allows entry of the desired power level (dBc) to be mea- sured.

￿DETECTION — Accesses a menu of detector modes including POSI- TIVE PEAK detection, AVERAGE detection and NEGATIVE PEAK detection.
