Why Teams Choose mRS Instruments

Field-accurate VNA's with no field hassle. We offer our ready-made hand-held VNA's that we have been producing and shipping since 2004, as well as partnering with both B2C and B2B customers to design custom solutions for a given application. Below is what sets us apart:

Feedpoint

Feedpoint accuracy

With our miniVNA Pro², mount the VNA at the antenna and control it over Class-1 Bluetooth (~100 m). This reduces coax loss and ferrite hassle, resulting in faster tuning as well as the results reflecting the actual feedpoint.

I/Q Generator

Built-in I/Q generator for SDR & IMD (Pro²)

Dual-channel AD9958 DDS with 0–55 dB per-channel attenuation and 1° phase steps lets you run SDR/IMD/phase experiments without extra generators or couplers.

Dynamic Range

Confidence below UHF: ≈100 dB S21 / ≈80 dB S11

≈100 dB (S21) / ≈80 dB (S11) below 230 MHz (Pro²). Stable traces and confident tuning for antennas, filters, and matching networks.

Software

Our own software

We've built the mRS Device Manager which offers: sweep control, multi-trace overlays with markers, calibration manager, Smith charting, and export (S2P, CSV/Excel, PDF/JPEG).

Value

Cost Efficiency

Professional grade performance and accuracy at a fraction of the cost of traditional VNA's. Since 2004, our instruments have proven to deliver reliability without the high price tag.

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.
