WCDMA Analyzer Measurement Guide : WCDMA FDD Analyzer Measurements : Setting Sweep Parameters
 
Setting Sweep Parameters
When setting up an WCDMA Demod Summary measurement, sweep parameters are set using the SWEEP Menu – WCDMA Demod Summary Measurements. When setting up an WCDMA RF measurement, sweep parameters are set using the SWEEP Menu – WCDMA RF Measurements.

CONTINUOUS
Toggles between continuous sweep and single sweep. In single sweep, the results of a sweep are displayed on the screen while the instrument awaits a trigger event to start a new sweep. The current state of the instrument is displayed in the status panel. With average/hold number (in TRACE menu) set to 1, or averaging is off, or no trace in trace average or hold, a single sweep is equivalent to a single measurement. A single sweep is taken after the trigger condition is met and the analyzer stops sweeping once that sweep has completed. To take one more sweep without resetting the average count, press the SWEEP ONCE button. This sweep control is also available in the status panel.
SWEEP ONCE
When sweep is set to single sweep, SWEEP ONCE triggers a single measurement sweep.
RESTART AVERAGING
Restarts the average frequency error value of the all the frequency measurements made.
HOLD
Hold will hold the current data display while the analyzer continues to capture and analyze data in the background.

SWEEP ONCE
When sweep is set to single sweep, SWEEP ONCE triggers a single measurement sweep.
POINTS
Sets the number of data points per sweep and displayed in each trace. The current value of points is displayed parenthetically, next to the sweep time in the lower-right corner of the display. Using more points provides greater resolution. Using fewer points compacts the data and decreases the time required to access a trace.
GATED SWEEP
Opens the GATED SWEEP menu. Gated Sweep menus remain accessible in WCDMA mode if the option is installed, but because WCDMA is not a TDD technology there is no application for the gated sweep function when performing WCDMA measurements.
