Description:

Measures Wide-Band Signals up to IMT-2000 2 Mbit/s

The MS8608A is a transmitter tester equipped with an internal spectrum analyzer, a modulation analyzer and a power meter. One tester covers the development to manufacturing of base stations, mobile stations and devices. The spectrum analyzer has resolution bandwidths up to 20 MHz, meaning that it can readily support measurement of a 2 Mbit/s (16 Mcps) wide-band signal for IMT-2000.

The modulation analyzer realizes all Vector Signal Analysis (VSA) functions through high-speed DSP processing. The power sensor can perform highly accurate power measurements of ±0.4 dB by using an amorphous power sensor. Up to three dedicated measurement software options (such as W-CDMA and GSM/EDGE) can be installed simultaneously. Input signals can be selected from either RF or I/Q inputs. For I/Q signals, balanced or unbalanced input can also be selected.

It is equipped with GPIB, RS-232C and 10 Base-T (optional interfaces for remote measurement. High-speed GPIB data transmission of 120 kbyte/s enables high-speed measurement on the manufacturing line. The monitor uses an easy-to-see 6.5 type TFT color LCD.
