The MS46121B Series delivers reliable RF and microwave performance in a uniquely compact and affordable form factor. Powered and controlled via USB from a user-supplied PC, this 1-port VNA is well-suited for passive device testing across manufacturing, R&D, and academic institutions.

With no internal memory and full external control, it’s also ideal for secure testing scenarios. The ability to operate up to 16 independent MS46121B VNAs in parallel dramatically increases throughput—especially in multisite test environments. The optional Scalar Transmission (Option 21) allows for coordinated scalar measurements across multiple units.

The ShockLine MS46121B offers simplicity and flexibility in a no-frills package without compromising test accuracy or speed, making it a smart choice for teams looking to scale testing without expanding equipment footprints.

  1. Compact & Portable Design – USB-powered, small enough to connect directly to the DUT.

  2. Frequency Range – Covers 150 kHz to 6 GHz for a wide range of RF/microwave applications.

  3. High-Speed Sweeps – Offers 120 µs/point sweep speed for efficient measurements.

  4. Scalar Accuracy – ±1.0 dB accuracy for 0 dB to -50 dB insertion loss levels (typical).

  5. Parallel Testing – Supports up to 16 VNAs on a single PC for true multisite test setups.

  6. Secure-Use Friendly – No onboard memory, ideal for classified or secure environments.

  7. Option 21 (Scalar Transmission) – Enables scalar magnitude-only measurements between multiple VNAs.

  8. ShockLine Software Support – Centralized control through intuitive PC-based GUI.
