Agilent / HP 8924E Shown

CDMA Base Station Simulator
Using industry standard ASIC's, the HP 8924E supports the protocol required to emulate a CDMA base station for mobile station test. The HP 8924E also includes a full OQPSK demodulator for CDMA mobile station transmitter and Frame-Error-Rate receiver measurements.

Functional CDMA Mobile Test
The HP 8924E supports both mobile or base station initiated call connect and disconnect. Enter the required RF channel number, wait for the mobile to acquire service, connect the CDMA mobile to the HP 8924E, and press the call key to make a CDMA phone call. To check voice quality, the HP 8924E offers a voice echo mode. When active, the voice echo mode delays and then re-transmits to the mobile-under-test any audio spoken into the CDMA mobile. An operator can quickly verify voice quality by speaking into the phone and then listening to the echoed audio in the mobile's handset.

CDMA Transmitter Tests
Transmitter tests include fast, DSP-based average power measurements from +38 dBm down to -10 dBm and accurate channel power measurements down to -50 dBm. The tuned channel power measurement reports the power in a 1.23 MHz measured bandwidth. By calibrating the tuned channel power measurement against the average power measurement, the HP 8924E achieves accurate low level CDMA power measurements. These two power measurement modes allow accurate verification of maximum power, open loop power control, and closed loop power control.

The HP 8924E measures transmitted waveform compatibility by the IS-98A recommended correlated power method "r" (rho). This measurement returns the percentage of transmitted power that correlates to the desired code. In addition, the "r" measurement reports the frequency error, modulated phase and amplitude error, and the carrier feedthrough.

CDMA Receiver Tests
The key performance parameter for CDMA mobile station receiver is Frame-Error-Rate performance in the presence of AWON. The built-in, high accuracy AWGN generator in the HP 8924E guarantees that FER tests provide a true picture of a CDMA mobile to correctly demodulate a signal in the presence of high interfering noise. The HP 8924E fully supports service Options 002 and 009 (RF loopback mode) to test receiver FER performance. The HP 8924E optimizes FER measurement time by employing confidence limit technology. With confidence limits, FER measurements are made in the fastest possible time.

Analog Capabilities
In addition to its powerful CDMA test capabilities, the HP 8924E retains full analog cellular test capability. Derived from the HP 8920B RF communications test set, the HP 8924E is HP-IB backwards compatible with most HP 8920B HP-IB commands. The HP 8924E includes as standard equipment a high stability timebase, a CCITT filter, a 6 kHz bandpass filter, and spectrum analyzer/tracking generator. In addition, the HP 8924E supports easy CDMA to analog handoffs and "one-button" analog cellular call processing for AMPS, NAMPS, TACS, NTACS, and JTACS phones. These analog features not only allow the HP 8924E to test the analog portion of dual-mode ratios, but also provides an effective suite of measurement tools for radio troubleshooting.
