Chapter 3, Operating Overview
Compensating for TX and RX Measurement Path Loss
Compensating for TX and RX Measurement Path Loss
The Software can compensate for losses (through cables, attenuators, couplers,
and so forth) between the Test System and the base station for the best accuracy in
average power and receiver measurements. The loss values are entered into the
Configuration Information Menu and are saved to memory if the Save
Info To Memory
feature is used.
Requirements You must know the following loss values:
• The total loss (in dB) between the base station’s transmitter test port and the
RF IN/OUT port of the PCS Interface.
• The total loss (in dB) between the RF IN/OUT port of the PCS Interface and the base
station’s receiver test port.
These values should include losses through any cables, splitters, attenuators, and
directional couplers used in your test setup.
Steps 1 From the main menu, select Configuration Information Menu.
2 Scroll to and select TX Measurement Path Loss and enter the loss between the
transmitter’s test port and the RF IN/OUT port of the PCS Interface. Once selected, you
can use the knob to scroll up and down in 1 dB increments or you may enter the value
directly using the DATA keys. Press ENTER or the knob when the correct value
appears in the inverse field.
3 Scroll to and select RX Measurement Path Loss and enter the total loss between
the PCS Interface’s RF IN/OUT port and the receiver’s test port.
4 To return to the main menu, press the Main Menu (k5) key.
Notes The loss values you entered in the steps above will not be saved unless you use the
Save Info to Memory feature. See "Saving Configuration Information to
Memory" on page 54.
