· One-box tester for CDMA measurement
When operating as an artificial base station, the MT8802A performs various operations such as evaluation of registration, origination, termination, conversation, loopback, handoff, disconnection from network, and disconnection from mobile station. These functions allow the terminal to be set to measure the transmission/reception performance, including waveform quality and frame error rate. During conversation, voice from the terminal can be looped back at the MT8802A, allowing the terminal operation to be checked easily.
The MT8802A can measure the following systems by changing the band mode; USA 800-MHz cellular band (TIA/EIA/IS-95A standard CDMA), USA 1.9 GHz PCS band (ANSI J-STD-008 standard).
The power level of multiple access probes can be measured in accordance with the standards. Standby output power can also be measured between access probes.
The waveform quality (r), frequency error, timing error (t), vector error, phase error, amplitude error, and origin offset can be measured.
The base station transmission power can be changed in steps to measure the terminal output power time response; pass/fail evaluation is performed according to the standards.
A high-accuracy thermocouple power sensor is built in. Accurate power measurement is ensured even for low-level signals by calibrating a narrow-band IF level meter using this wide-band power meter.
The frame error rate can be measured and pass/fail evaluation performed based on the confidence level. The built-in high-accuracy signal generator and AWGN generator permit traffic channel demodulation testing in a noisy environment.
The MT8802A has general analog measurement functions, too. FM TX/RX testing is easy and efficient using the built-in signal generator, AF oscillator, RF analyzer (narrow-band power meter, frequency counter, FM measurement), and audio analyzer functions.
The spectrum analyzer with synthesized local oscillator covers a frequency range of 10 MHz to 3 GHz with a resolution of 1 Hz.
