The size of a deck of cards, the USB-powered Planar R54 VNA is a 1-port VNA capable of measuring S11 from 85 MHz to 5.4 GHz and designed for use with with any Windows PC or laptop. Its compact form factor oftentimes enabled direct connection to the device under test, eliminating uncertainty associated with a test cable prone to flexure and damage. The free, lightweight VNA application connects to the R54 with a standard USB cable, creating a future-proof solution that significantly enhances ease of use compared with conventional instruments.

The R54 provides a wide variety of analysis capabilities, including time-domain with gating and DTF measurements at no additional cost. Collection of metrology-grade S-parameter test results can be achieved manually or through automation in Python, MATLAB, Excel, C++, VB.NET, or LabVIEW.
Frequency range: 85 MHz to 5.4 GHz
Measured parameters: S11 as Log magnitude, DTF, Smith, and more
Sweep types: Linear frequency, log frequency, segment
Effective directivity: 45 dB below 4 GHz; 40 dB up to 5.4 GHz
Measurement speed: 200 µs per point
Output power setting: High or Low
Up to 100,001 measurement points per sweep
Applications of the R54 include antenna matching, cable and connector quality control, antenna production quality assurance, field testing and troubleshooting of cables, material measurements, and many others. Curious to see what other users think of this device?
