  • Specification

The MS2034B VNA Master + Spectrum Analyzer is a compact powerhouse built for RF engineers and technicians working in the field across industries such as aerospace, defense, and wireless communications. This combination analyzer replaces multiple instruments, offering S-parameter, Distance-To-Fault, and spectrum diagnostics in a single, field-optimized tool.

Its VNA range (500 kHz to 4/6 GHz) covers typical communication bands and enables error-corrected testing of components like antennas, cables, filters, switches, and circulators. The integrated spectrum analyzer adds advanced diagnostics for transmitters and receivers, with powerful features like 10 MHz RBW, fast sweep optimization, and low phase noise for clean spectrum visualization.

With distance domain analysis, the MS2034B also helps locate faults in aircraft and naval cable bundles. For interference resolution, the optional Interference Analyzer (Option 0025) and AM/FM/PM demodulation (Option 0509) provide advanced visualization and audio playback tools.

This all-in-one analyzer delivers lab-grade measurement precision in a field-ready touchscreen interface, significantly reducing the number of tools needed for installation, commissioning, and troubleshooting of wireless infrastructure and defense systems.
