HP 83205A-001
CDMA Cellular Adapter
HP 83205A Product Details
The Agilent Technologies 83205A CDMA/CDPD Cellular Adapter adds optional
CDMA and/or CDPD measurement capability to the Agilent Technologies 8921A
for IS-95A/97 CDMA base station testing and/or CDPD Mobile Data Base Station
(MDBS) testing. The 8921A retains its full capability for testing the
analog performance of dual-mode CDMA base stations.
Features:
- Adds the following CDMA measurements to the Agilent Technologies 8921A
- Code domain power, timing, and phase analysis
- Waveform quality (rho), frequency error, and pilot time offset
- True-average power and CDMA channel power measurements
- Built-in Added White Gaussian Noise (AWGN) source for calibrated Eb/No
settings
- Optional CDPD Mobile Data Base Station (MDBS) test capability
