Step Action

9 Set the Agilent 8935 as follows:

- Measure mode to CDMA Anl

- Frequency to the CDMA calibration target frequency

- Input Attenuation to 0 dB

- Input port to RF-IN

- Gain to Auto

- Anl Dir to Fwd

10 Turn on the Agilent 8935 signal output.

11 Set the Chn Pwr Cal to Calibrate and select to calibrate.

12 Measure and record the channel power reading on the measuring Agilent 8935 as result

B ________________________.

13 Turn off the Agilent 8935 signal output and disconnect the equipment.

14 Calculate the Power Calibration Delta value. The delta value is the power meter measurement minus

the Advantest measurement.

Delta = A - B

Example: Delta = -0.70 dBm - (-1.25 dBm) = 0.55 dBm

Example: Delta = 0.26 dBm - 0.55 dBm = -0.29 dBm

These examples are included to show the mathematics and do not represent actual readings.

NOTE

Add this delta value to the TX Cable Loss value during In-Service Calibration (see Step 4 in

Table H-6).
