1.1 General
The MT8801C Digital Mobile Radio Transmitter Tester is a test platform having all
the hardware needed to test digital mobile communication terminals. The perfor-
mance of radio equipment can be efficiently evaluated by using it with optional test
software.
The frequency usage of radio equipment is becoming more efficient, and the equip-
ment is becoming faster and more digitalized. The MT8801C Spectrum Analyzer
function (option 07) is suitable for signal analysis of such equipment.
Its C/N, distortion, frequency and level accuracy, and other basic performances are
excellent. Operation can be performed easily using software menu screens.
Because frequency domain and time domain waveforms can be switched and dis-
played with one touch, signal analysis of radio equipment can be carried out effi-
ciently.
A MEASURE function allows measurements corresponding to various applications.
Noise measurements, C/N ratio measurements, occupied frequency bandwidth mea-
surements, adjacent channel leakage power measurements, mean power measure-
ments, and evaluation of other radio equipment performances can be easily per-
formed.
Because the Spectrum Analyzer function (option 07) uses high-speed digital signal
processing technology, its main transmitting and measurements can be performed
quickly and accurately.
