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 cable loss value.

Follow the procedure in Table H-3 to perform the Agilent 8935 Power

Delta Calibration procedure.

Table H-3: Agilent 8935 Power Delta Calibration Procedure

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 NO TAG.

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

(see Figure H-6).

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.

7 Connect the short RF cable between the Agilent 8935 Duplex Out port and the RF–IN/OUT port (see

Figure H-7).

8 Ensure that the source Agilent 8935 settings are the same as in Step 3.
