The MS2035B VNA Master + Spectrum Analyzer is a versatile, compact tool engineered for RF field teams who need more than basic network analysis. Covering up to 6 GHz, it allows engineers to troubleshoot everything from antennas and cables to filters and transmitters—with industry-leading dynamic range and phase noise performance for reliable field results.

Its 1-Path, 2-Port VNA mode delivers full S-parameter testing, while the spectrum analyzer mode (9 kHz–6 GHz) simplifies signal visualization and interference hunting. Users can choose between the standard S-parameter GUI and Field Mode, which mimics the layout of simpler cable & antenna testers while maintaining the same high precision.

Thanks to features like PIM hunting compatibility, Distance-To-Fault analysis, real-time demodulation, and advanced sweep routines, this analyzer becomes indispensable in scenarios such as 5G backhaul installation, military radar maintenance, and aviation signal chain verification.

Built to withstand harsh RF and environmental conditions, the MS2035B ensures test reliability, portability, and simplified toolkits—ideal for shipboard, airborne, or remote field environments.

  • Dual-Function Handheld – Combines 1-Path, 2-Port VNA (500 kHz to 6 GHz) and Spectrum Analyzer (9 kHz to 6 GHz).

  • Vector-Error Corrected S-Parameters – Ensures high accuracy for S11, S21, etc., in real-time.

  • Touchscreen Interface – Large 800x600 display for intuitive diagnostics in demanding conditions.

  • Field Mode GUI Option – Toggle between full VNA view and simplified Cable & Antenna test mode.

  • Distance Domain Analysis – Standard feature (with firmware v1.20+) for fault location in shipboard/aircraft wiring.

  • PIM Hunting Support – Works with MW82119B PIM Master to detect passive intermodulation sources.

  • AM/FM/SSB Demodulator – Built-in signal listening helps identify interference sources.

  • Advanced Sweep Optimization – Intelligent sweep engine for fast, accurate spectrum measurements.

  • Interference Analyzer Option (0025) – Powerful tool for isolating and identifying interferers in real time.

  • Demodulation Option (0509) – Adds AM/FM/PM spectrum and audio analysis for deeper modulation insight.
