The MS46131A Series of modular 1-port VNAs redefines flexible testing for high-frequency, passive component analysis. Available in three models covering up to 43.5 GHz, these VNAs utilize Anritsu’s patented NLTL (Nonlinear Transmission Line) technology to shrink the internal design without compromising performance.

The small, USB-controlled form factor means engineers can place the analyzer directly at the DUT, minimizing cable loss and enhancing test repeatability. Each model supports high-speed measurements and provides outstanding corrected directivity, ensuring confidence in even the most demanding S11/Return Loss testing tasks.

Engineers can run up to four MS46131A units in parallel from a single PC, significantly increasing measurement throughput—especially in production settings. The absence of onboard memory makes it a secure option for sensitive testing environments.

From 5G component testing to modular lab setups, the MS46131A offers precision and portability in one of the most compact packages on the market.

  1. Three Frequency Models – Choose from 8 GHz, 20 GHz, or 43.5 GHz for targeted RF/microwave applications.

  2. Compact & Portable – Lightweight design brings the VNA port directly to the DUT for better measurement stability.

  3. VNA-on-Chip Architecture – NLTL technology enables reduced size, cost, and cable dependency.

  4. Fast Sweep Speeds – Optimized for production testing and high-throughput environments.

  5. Excellent Corrected Directivity – Delivers highly repeatable and accurate S11/Return Loss measurements.

  6. Parallel Testing – Control up to four VNAs simultaneously from a single PC.

  7. No Onboard Memory – Ensures secure testing in classified or restricted environments.

  8. Ideal for 5G Testing – Perfect for characterizing passive 5G components and mmWave front ends.
