Power Delta Calibration – continued
FEB 2005 1X SC 4812T Lite BTS Optimization/ATP H-11
PRELIMINARY
Agilent 8935 Series E6380A
Power Delta Calibration
The Agilent 8935 (formerly HP 8935) Communications Test Set
modified with either Option 200 or R2K and E4432B Signal Generator
Test Equipment combination can be used for ISC of IS–2000 CDMA 1X
as well as IS–95A/B Operation Modes. The Power Delta Calibration is
performed on the Agilent 8935. After the Offset Value has been
calculated, add it to the TX Test Cable Insertion Loss Value.
Perform the procedure in Table H-3 to perform the Agilent 8935 Power
Delta Calibration Procedure.
Table H-3: Agilent 8935 Power Delta Calibration Procedure
n Step Action
NOTE
Perform this procedure after Test Equipment has been allowed to warm–up and stabilize for a
minimum of 60 minutes.
After it is warmed–up and stabilized, calibrate the Test Equipment as described in the “Test
Set Calibration” section of Chapter 3.
1
Zero the Power Meter prior to connecting the Power Sensor to the RF Cable from the Signal
Generator.
NOTE
For best accuracy, always re–Zero the Power Meter before connecting the Power Sensor to the
component being calibrated.
2 Connect a short RF Cable between the Agilent 8935 Duplex Out port and the HP437 Power
Sensor.
Refer to Figure H-5.
3 Set the Agilent 8935 Signal Source as follows:
Measure Mode to CDMA Gen
Frequency to the CDMA Calibration Target Frequency
CW RF Path to IQ
Output Port to Dupl
Data Source to Random
Amplitude to 0 dBm
4 Measure and record the Power Value Reading on the HP437 Power Meter.
5 Record the Power Meter Reading as Result A.

6 Turn off the Agilent 8935 Signal Source Output, and disconnect the HP437.
NOTE
Leave the settings on the Source Agilent 8935 for convenience in the following steps.
