Description: Every major radio communication system in the world, including GSM/DCS1 800/PCS1900, IS-136A, PDC and PHS, can be evaluated using just one MT8801B Radio Communication Analyzer, cover- ing the 300 kHz to 3GHz frequency band in one hardware platform, and the dedicated measurement software options. The call processing test and sensitivity test using loopback method are possible for GSM/DCS1800/PCS1900 and IS-136A.
In addition, connection testing, as well as send testing while communicating, are also possible for PDC and PHS measurement by using the call processing function. And the PDC uplink RCH can be monitored (RSSI, estimated error rate) too. FM radio transmission /reception tests are simplified by using the optional analog measurement function. And the optional spectrum analyzer function covering 10 MHz to 3 GHz is very useful for maintenance as well as for measuring spurious near carrier on production lines. GPIB and RS-232C interfaces are standard, so MT8801B can be incorporated easily in- to automated production lines or on-site automated testing systems. The time required for testing equipment on production lines is greatly reduced using the high-speed adjacent channel power and occupied bandwidth measurement functions based on Anritsu's proprietary measurement algorithm and DSP (Digital Signal Processing). Furthermore, major transmission test items such as transmission frequency, modulation accuracy (phase error), transmission power, rise/fall characteristics of burst wave, adjacent channel power, etc., can be measured and judged pass/fail for limit value of the each item.
This unit has the following features:
Single unit for GSM, IS-136A, PDC, and PHS
Batch measurements of transmission test items
Only about 1 second is required to measure all major transmission test items, including frequency, modulation accuracy, origin offset, transmission rate, transmission power, leakage power during carrier off, rise/fall edge characteristics, occupied bandwidth, and adjacent channel power. Pass/fail decisions for limit value of each test item can also be displayed
Analog measurement function (Option 01)
The MT8801B has general analog measurement functions too. Efficient FM TX/RX testing is made easy by built-in signal generator, AF oscillator, RF analyzer (power meter, frequency counter, FM measurement) and audio analyzer functions. This function is especially useful for the IS-136A analog test.
Transmission measurement characteristics such as frequency, power, and frequency deviation can be measured easily.
Reception measurement: An FM modulated signal is output to permit measurement of the frequency and level of the AF signal from a receiver, as well as SINAD and distortion.
Spectrum analyzer function (Option 07)
The spectrum analyzer with synthesized local covers a frequency range of 10 MHz to 3 GHz with a resolution of 1 Hz. In addition to a C/N of -115 dBc (100 kHz offset), the RBW can be set to 300 Hz to 1 MHz, the VBW to 3 to 100 kHz, and the sweep time in the frequency domain to I 00 ms to 1 000 s (1ms to 1000 s in time domain). The total level accuracy is an astonishing ±1.5 dB due to the analyzer's excellent linearity, and the level calibration function. Moreover, the average noise level is just -85 dBm max. (at 1 0 MHz to 1 G Hz), and the secondary harmonic distortion is -60 dB max. (100MHz to 1.5 GHz).
