The Anritsu MS2034A VNA Master is a handheld vector network analyzer (VNA) with broad spectrum analysis capability from 9 kHz to 4 GHz. Utilizing superior Frequency Domain Reflectometry (FDR) instead of traditional DC pulse TDR techniques, this instrument provides precise 1-port measurements of return loss, VSWR, cable loss, Distance-To-Fault (DTF), and Smith Chart measurements in field environments.

When connected to a 2-port cable, the VNA Master can measure cable loss, phase, and group delay, offering simplified S11 and S21 measurements for cables and antennas in field applications.

The MS2034A VNA Master employs vector correction following open-short-load calibration to ensure measurement accuracy, repeatability, and quality for both 1-port and 2-port measurements. This advanced approach eliminates systematic errors associated with 1-port reflection measurements, including directivity, source match, and reflection tracking. For 2-port transmission measurements, it removes transmission response errors and transmission source match errors through 1-path, 2-port correction.

The VNA Master plus Spectrum Analysis option extends capabilities to include spectrum monitoring, interference analysis, and general purpose signal measurements from 9 kHz to 7.1 GHz. Standard measurements include field strength, occupied bandwidth, channel power, adjacent channel power ratio, and carrier to interference (C/I) ratio, with built-in AM/FM/SSB demodulator for identifying interfering signals.
