To Change the Measurement Display
To Use Measurement Averaging
The AVG (average) function allows you to reduce the effects of a rapidly
changing measurement by displaying the average value of a number of
measurements.
1. Position the cursor in front of the measurement’s unit-of-measure.
2. Press and release the SHIFT key, then the INCR × 10 key to select the AVG function.
The default number of average samples is displayed below the measurement.
• Enter the desired number of measurement samples to be used for calculating the
average, or
• Press the ON/OFF key to use the currently-displayed number of samples.
3. To turn averaging off, position the cursor in front of the unit-of-measure and press re-
lease the SHIFT key, then the INCR × 10 key, then the ON/OFF key to turn averaging
off.
Front-Panel Example
The following front-panel operation averages Avg Power measurements over
10 samples.
1. Move the cursor in front of the unit-of-measure for the Avg Power measurement.
2. Press and release the SHIFT key, then the INCR × 10 key to select the AVG function.
3. Enter 10 using the DATA keys and press the ENTER key. The abbreviation Avg will
appear below the Avg Power measurement field.
HP-IB Example
The following HP-IB command also averages Avg Power measurements over 10
samples.
“DISP CCNT;MEAS:CDM:AVGP:AVER 10;AVER:STAT ON”
When Averaging is used, the displayed value will ramp (as opposed to step) in
response to changes in the measured values.
Pressing the MEAS RESET key clears the measurement history for all
measurements and restarts the averaging process.
