Chapter 1, Calibrating the Test Set
Determining RF Path Loss
Determining RF Path Loss
The following procedure describes how to use the Test Set’s signal generator and
analyzer to determine path loss.
NOTE:
The Test Set’s attenuator auto-ranging algorithm, used for adjusting gain in the RF analyzer
path, estimates the expected power level from the phone using the open loop power control
formula. External path loss, entered in the procedure below, is applied to the auto-ranging
algorithm to ensure the analyzer is not overdriven or underdriven.
Procedure Prerequisites
Provide a reference cable, cable and hardware in RF path to MSUT, and adapters
You must provide a reference cable and the cable adapters necessary to mate the
reference cable and the hardware that will be used in the path from the Test Set to
the MSUT. Choose a reference cable with as little loss as possible.
Zero the Average Power measurement
Refer to
"Zeroing Average Power Measurements" on page 36
if necessary, and then
return to this procedure.
