3. Correct for RF Path Loss.
Manual Operation:
1. Press then release the SHIFT key then press the
TESTS key to display the CONFIGURE
screen, if it is not already displayed.
2. Position the cursor at the RF In/Out field.*
3. Enter the RF path loss. For example, if the RF
path loss is 2 dB, enter -2 in the RF In/Out field.
4. Position the cursor at the RF Level Offset field.
5. Select On to apply the offset.
6. Press the PREV key to return to the CDMA

If you need a method for measuring path loss, refer to
The Test Set corrects for path loss by changing displayed values. Example: If an RF path loss of -2 dB is
entered in the RF In/Out field, and RF Level Offset is turned on, input power measurements will be 2 dB
greater than the same measurement with RF Level Offset turned off.
Correcting for RF path loss allows the Test Set to achieve accurate gain settings in the RF analyzer path.
*If you are using an external duplexer, enter the path loss in the Duplex Out and Antenna In fields (displayed
when the PCS Mode field is set to "Off").
HP-IB Syntax:
"CONF:OFL:RFIN -2;MODE 'ON'" !enters an RF path loss of 2 dB for the path to the RF In/
