Measurement
Transmitter power for using the PCS Interface is available in addition to other
measurements from the Test Set.
•
Transmitter Power measurements
Use the following command string to query the power measurement from the
PCS Interface.
To the PCS Interface>
TX:INP:POW?
NOTE:
The power detector temperature compensation is automatically performed when the
TX:INP:POW? command string is used to make a power measurement.
When performing the power measurement, the RF generator level should be set to less than
−
50 dBm if the RF IN/OUT port is used, or set to less than
−
30 dBm if the RF OUT only
port is used.
•
Other Test Set measurements
Refer to the Test Set’s programming guide for making other measurements.
NOTE:
Since the Test Set does not automatically correct for the frequency and amplitude changes
due to the conversions in the PCS Interface, absolute frequency (using the Auto Tune
mode) and absolute amplitude measurements will not be accurate. For example:
Absolute TX frequency = (1050 or 1060 MHz conversion) + Test Set’s frequency reading
