Vector network analyser and vector voltmeter capability to field portable instruments

Anritsu Company has added vector network analyser (VNA) and vector voltmeter (VVM) measurements to its industry standard Site Master instruments. The latest iteration of the Anritsu Site Master MS2085A and MS2089A are the most capable ever field portable instruments employed by the world’s RF communications engineers. Already featuring a cable and antenna analyser and spectrum analyser, the new VNA and VVM options expand the applications supported to include filter and amplifier testing in the field and maintenance of radar and antenna arrays, including airfield VOR and ILS navigation systems.

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

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

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.

The VNA and VVM options are available immediately. Existing instruments can be updated to include the new measurements.
