Chapter 1, Calibrating the Test Set
Zeroing Average Power Measurements
2. Lower the Test Set's output power if necessary.
Manual Operation:
1. Press the PRESET key, which will set RF
Power to a level that will not degrade Average
Power zeroing, or turn off all sources as
follows:
2. Press the GEN CTRL key to display the
GENERATOR CONTROL
CDMA
3. Turn off Sector A Power, Sector B Power, and
AWGN (by pressing the ON/OFF key on the
Test Set's front panel).
Turning off power from the CDMA generators will prevent power from cross-coupling internally to the
RF IN/OUT path during Average Power measurement zeroing.
Presetting the test Set (*RST HP-IB command) will turn off Sector B and AWGN, and will lower Sector A
Power to a level that will not affect zeroing the Average Power measurement, making it unnecessary to turn
Sector A Power off.
