Overview

The Anritsu Site Master MS2085A and MS2089A are handheld analyzers for installing, maintaining and troubleshooting RF communication systems up to 6 GHz. Both models combine cable and antenna analysis with an optional vector network analyzer, and the MS2089A adds an integrated spectrum analyzer. Typical uses include broadcast and cellular sites, distributed antenna systems (DAS), satellite monitoring, interference analysis, and aerospace and defense work.

MS2085A cable and antenna analyzer

The MS2085A is a cable and antenna analyzer covering 5 kHz to 4 GHz or 6 GHz. It weighs less than 7 lb and has an IK08-rated 10-inch touch screen. It measures return loss, cable loss, VSWR, distance-to-fault, 1-port phase and Smith chart, with time domain reflectometry available as an option. It can generate PDF/HTML reports and manage cable lists directly on the instrument.

MS2089A with spectrum analyzer

The MS2089A comes in two configurations: a 5 kHz to 4 GHz cable and antenna analyzer with a 9 kHz to 4 GHz spectrum analyzer, or a 5 kHz to 6 GHz cable and antenna analyzer with a 9 kHz to 6 GHz spectrum analyzer. It weighs less than 8.5 lb and uses the same IK08 10-inch touch screen. Spectrum analyzer options include real-time spectrum analysis, IQ capture and streaming, interference finding, channel scanning, coverage mapping, and WCDMA, LTE FDD/TDD and 5G NR FR1 signal analysis.

Vector network analyzer and vector voltmeter options

The optional VNA is a 2-port, 1-path analyzer to 4 or 6 GHz with a 380 µs/point sweep speed. It ships with a default ReadyCal calibration and also supports mechanical and InstaCal user calibrations, with 16 display formats including log magnitude, VSWR, phase, Smith chart, group delay and polar. The vector voltmeter option is intended for tasks such as matching cable phase.

Software compatibility

The instruments work with Anritsu Remote and Report Tools (ARRT), the IQ Signal Master MX280005A vector signal analysis software, the Mobile InterferenceHunter MX280007A and the Vision MX280001A remote spectrum monitoring software.
