Why Teams Choose mRS Instruments

Field-accurate VNAs without the field hassle. We have designed and shipped hand-held VNAs since 2004, and we build custom solutions with companies and individuals for their specific application.

~100 mBluetooth range at the antenna

Measure at the feedpoint

Mount the miniVNA Pro² at the antenna and control it wirelessly. Less coax loss and ferrite hassle, faster tuning, and readings that reflect the real feedpoint.

1°Phase steps, two DDS channels

Built-in I/Q generator

Two AD9958 DDS channels with 0–55 dB attenuation each (Pro²): run SDR, IMD and phase experiments without extra generators or couplers.

≈100 dBS21 dynamic range below 230 MHz

High dynamic range

Plus ≈80 dB on S11 (Pro²). Stable traces and confident tuning for antennas, filters and matching networks.

Custom Solutions

Tailored RF Instrumentation & AI-Driven Workflows

We go beyond standard off-the-shelf testing. Whether you need embedded OEM modules for industrial machinery or remote-controlled monitoring systems, we engineer VNAs to your exact specifications. From multi-port configurations to AI-enabled data analysis via a platform, we integrate precision RF measurement directly into your ecosystem.

  • Custom Hardware Architecture: Multi-port configurations and frequency front-ends optimized specifically for your required bands.
  • Embedded Integration: Flexible communication interfaces (USB, Ethernet, SPI) designed to act as add-on boards within your existing equipment.
  • Automated Control: Remote command capabilities that allow the VNA to trigger and control external devices based on real-time measurement results.
  • AI-Ready Data: Structured data export (S-parameters, CSV, JPEG) optimized for training AI/ML models and limit-line screening.
  • Precision Signal Generation: High-dynamic range utilizing DDS (Direct Digital Synthesis) technology for clean, harmonic-free signal output.
