Dynamic Power Measurements for cdma2000 on the Agilent 8960 Wireless Test Set
A critical component of ensuring the CDMA device's operability is the calibration and verification of transmitter power. Today, typical designs utilize a switched amplifier, in for higher power use, and out for lower power situations. It is important that the output power be calibrated, both as a function of level and of frequency. Operation at maximum power requires special calibration, as well. Most mobile stations (MS) will operate in two frequency bands; the calibration must be performed in each band.
This paper focuses on how the Agilent's 8960 wireless test set is used by CDMA MS developers and manufacturers to expedite the creation of transmitter power calibration tables and to reduce test time for this calibration in both the high and low power ranges.
