The company says the latest iteration of the Anritsu Site Master MS2085A and MS2089A are the most capable ever field portable instruments used by the world’s RF communications engineers. Already featuring a cable and antenna analyzer and spectrum analyzer, the new VNA and VVM options expand the applications supported to include filter and amplifier testing in the field as well as maintenance of radar and antenna arrays including airfield VOR and ILS navigation systems.

 The VNA offers a ReadyCal option that enables testing immediately on arrival on site plus exceptional calibration stability reducing the requirement for repeated recalibrations in the field. A measurement dynamic range in excess of 100 dB facilitates the testing of filters and diplexers commonly found in communication base stations, and the source power ranges from -45 dBm to 9 dBm adding amplifier test capability. The new Site Master VNA sweep speed is faster than any previous generation to simplify alignment and tuning of devices.

 The VVM is said to be an essential instrument for cable phase matching in complex phased array antenna systems such as the VOR/ILS systems located at all major airports. Phase matching of multiple cables is simplified with a table display of individual results on a single screen.

 With the addition of a VNA and VVM instrument the new MS2085A and MS2089A Site Master builds on its status as the instrument of choice for technicians installing and maintaining the world’s communication networks.
