To Change the Measurement Display
To Specify Units-of-Measure for CRT Display
Most measurements, data functions, and instrument functions allow you to specify
which unit-of-measurement should appear on the CRT display.
1. Position the cursor in front of the present unit-of-measurement.
2. Press the key labeled with the desired unit.
Front-Panel Example
The following front-panel operation causes the Test Set to display Avg Power in
units of Watts instead of dBm.
1. Press the PRESET key.
2. Press the CALL CTRL key to access the CDMA CALL CONTROL screen.
3. Move the cursor in front of the unit-of-measure for the Avg Power measurement
(dBm).
4. Press the RATIO W key. The measurement value is changed immediately to display in
Watts.
HP-IB Example (DUNits Command)
The following HP-IB command causes the Test Set to display Avg Power in
units of Watts instead of dBm. The DUNits command will only change the Test
Set’s displayed units, not the units used for data transfer through HP-IB.
