R180 1-Port 18 GHz Analyzer

R180 Vector Network Analyzer (cable and antenna analyzer) delivers lab grade performance in a handheld device. This patented (US Patent 9,291,657) analyzer can be connected directly to the antenna or other DUT without the need for a test cable, eliminating measurement uncertainties inherent to cables. Resulting in highly dependable performance and calibration stability. The 1-port VNA comes with all the features engineers have come to expect included standard in our software.


The R180 1-Port VNA is available with an IP54 add-on option:

As defined in international standard IEC 60529, the Ingress Protection Rating classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures.

The standard configuration R180-02 incorporates an N-type male test port connector. Other connectors are available by special order:

  • R180-01 – N-type female
  • R180-11 – 3.5mm female
  • R180-12 – 3.5mm male


R180 VNA includes an RF measurement module and R software application which runs on Windows or Linux operating system on a PC, laptop, tablet, or x86 board computer connecting to the measurement hardware via USB interface. R software can be installed on multiple computers that share the use of the analyzer measurement module. The handheld (R180 cable and antenna analyzer is powered and operated through USB connection to an external PC or an external 5V charger. The R180 network analyzer can be used in the field, in the laboratory, and in production testing. The VNA can be integrated into production test system via Manufacturing Test plug-in.


VNAs and ACMs are delivered with factory calibration certificates containing no data. The add-on option for ISO17025/Z540-1 Accredited, Traceable Calibration Certificate and Uncertainties is available and needs to be specified at time of order.

  • - Frequency range: 1 MHz to 18 GHz
  • - Measured parameters: S11 as Log magnitude, DTF, Smith, and more
  • - Sweep types: linear frequency, log frequency, segment
  • - Effective Directivity: 42 dB
  • - Measurement speed: 100 µs
  • - Impedance: 50 Ohm

Due to its measurement accuracy, ultra-compact size and elimination of a test cable, the R180 cable and antenna analyzer (reflectometer) can be used for antennas and antenna feeders in the field, as well as laboratory and production testing in a wide variety of industries including design and production of various IoT hardware components, materials testing, medical devices, aerospace applications, etc.
