Advantest R3267 Power Delta Calibration

The Advantest R3267 spectrum analyzer and R3562 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 R3267. After the offset value has been calculated, add

it to the TX cable loss value.

Preliminary Advantest Test Equipment Set–up

To provide proper operation during power delta calibration, be sure the

R3267 is connected to the R3562 as shown in Figure F-17.

Power Delta Calibration

Follow the procedure in Table H-2 to perform the Advantest R3267

Power Delta Calibration procedure.
