Chapter 4, CDMA Transmitter Tests
Measuring the Range of Open Loop Output Power
5. Measure the MSUT’s power level.
HP-IB Syntax
"CDMA:TX:POW:MEAS ’Chan Power’"
!selects the Channel Power measurement.
"MEAS:CDM:CHAN?" !queries the channel power measurement.
Manual Operation:
1. Position the cursor next to the field shown in
the figure.
3. Press the knob to display the Choices menu.
4. Select Chan Power from the list of choices
.
(See ranges, below).
5. Read the power level.
Channel Power measurement range = -50 to +35 dBm/1.23 MHz BW.
Note: If Sector A Power is set to a high level, such as -25 dBm, and an Average Power measurement is made,
the Test Set will display a measurement value that is higher than you would expect from the MSUT. This
measurement result is an artifact of the Test Set’s broad band power meter, and does not affect Channel Power
measurements, which must be used when the MSUT power level is below -10 dBm/1.23 MHz BW.
