MS8609A Digital Mobile Radio Transmitter Tester

Product picture



Measures Wideband Signals up to 20 MHz

The MS8609A Digital Mobile Radio Transmitter Tester has a built-in spectrum analyzer, modulation analyzer, and power meter. One tester supports all the measurements needed to develop and manufacture base stations and mobile stations as well as to construct and maintain base stations. The spectrum analyzer resolution bandwidth of 20 MHz readily supports measurement of wideband signals. The modulation analyzer uses high-speed DSP to support all Vector Signal Analysis (VSA) functions.

Power can be measured with an accuracy of ±0.4 dB using the amorphous power sensor. Up to three dedicated measurement software options for W-CDMA, GSM/EDGE, etc., can be installed simultaneously and input signals can be selected from either RF or I/Q. Balanced or unbalanced input can also be selected for I/Q signals. Remote measurement is supported by GPIB, RS-232C and 10Base-T (optional) interfaces and the 120 kbyte/s speed of the GPIB I/F supports high-speed measurement on production lines.

The screen uses an easy-to-read 6.5-inch TFT color LCD.
