Overview
  • Excellent performance for evaluating W-CDMA modulation signals. This makes it ideal for the development and manufacture of W-CDMA radio transmitters (base station and mobile).  GSM/EDGE, HSDPA, WLAN/802.11, CDMA, 1xEVDO, and Pi/4DQPSK (PHS, PDC, IS-136) measurements are also supported. 
  • The built-in spectrum analyser (standard) covers a resolution bandwidth of up to 20 MHz. It is ideal for evaluating devices such as base station power amplifiers, due to its wide dynamic ranges of 68 dB (typical for 5 MHz offset) and 75 dB (typical for 10 MHz offset) for adjacent channel power (ACP) measurement (sweep method). A new average detection mode permits high-accuracy measurement of signal power with this noise-like spreading modulation.
  • The built-in power meter (standard) integrates an amorphous power sensor for high-accuracy (+-0.4 dB) power measurements.

MS8608A and MS8609A are transmitter testers equipped with an internal spectrum analyzer, a modulation analyzer and a power meter. Just one tester can cover the development and manufacturing of base stations and mobile stations, as well as the construction and maintenance of base stations.

  • MS8608A supports 9 kHz-7.8 GHz and high power inputs up to +40 dBm.
  • MS8609A supports 9 kHz-13.2 GHz and input power up to +20 dBm.

The spectrum analyzer has resolution bandwidths up to 20 MHz, meaning that it can readily support measurements of wide-band signals. The modulation analyzer realizes all Vector Signal Analysis (VSA) functions through high-speed DSP. The power sensor can perform highly accurate power measurements of ±0.4 dB by using an amorphous power sensor.

Up to three measurement software options (such as W-CDMA, GSM/EDGE, HSDPA, WLAN/802.11, CDMA, 1xEVDO) can be installed simultaneously. Input signals can be selected from RF or I/Q inputs. For I/Q signals, balanced or unbalanced input can also be selected.

Each tester can be equipped with optional GPIB, RS-232C, and 10BASE-TEthernet interfaces for remote measurement. High-speed GPIB data transmission of 120 kbyte/sec enables high-speed measurement on the manufacturing line. The monitor uses an easy-to-see TFT color LCD.
