Field analyzers gain vector functions
Anritsu’s Site Master cable and antenna analyzers are now available with optional vector network analyzer (VNA) and vector voltmeter (VVM) capabilities. These additions extend their use to field testing of filters and amplifiers, as well as maintenance of radar and antenna systems, including VHF omnidirectional range (VOR) and instrument landing system (ILS) navigation equipment.
The two-port, one-path VNA covers 5 kHz to 4 GHz or 6 GHz. Calibration options include standard open/short/load accessories, the one-step InstaCal module, or factory ReadyCal for immediate measurements. With over 100 dB of dynamic range and –45 dBm to +9 dBm output power, it supports testing of filters, diplexers, and amplifiers in communication base stations. A 380-µs/point sweep speed accelerates alignment and tuning.
The VVM performs cable phase matching in complex phased array antenna systems, such as VOR/ILS systems at major airports. A table display of individual results simplifies phase matching of multiple cables.
The VNA and VVM options for the Site Master MS2085A and MS2089A portable analyzers are now available, with existing instruments eligible for upgrade.
