ARINST VNA-PR1 portable two-port vector network analyzer is designed to measure the matching characteristics of passive and active radio devices (antennas, cables, filters, attenuators, amplifiers), check the integrity of high-frequency cables, measure their parameters and other amateur radio measurements.

The device measures parameters S11 and S21, voltage standing wave ratio (VSWR), impedance, admittance, phase, group delay time (GD), losses and distance to cable fault.

For whom?

The ARINST VNA-PR1 analyzer is made in a robust aluminum case in the form of a mobile device with autonomous power supply and is intended primarily for work directly on the site, since it is characterized by low power consumption with its low weight and compact size. The analyzer will be especially useful for telecommunications companies that install and maintain antennas, amplify cellular communications, etc. It can be used by service centers and repair teams to perform RF analysis of cables and antennas on-site during commissioning or repair work. In addition, the device is ideal for workshops, radio amateurs, educational institutions and laboratories.

The device has a 4-color resistive screen for displaying measurement results and controlling the device.

For example, using the device, you can perform the following work:

  • Perform impedance matching using the Smith diagram
  • Measure the standing wave coefficient
  • Measure the frequency response of active devices
  • Measure attenuation in the cable
  • Measure the distance to damage in the cable or its length

Attention! All devices are calibrated by the manufacturer. Removable SMA adapters screwed onto the device connectors are taken as the reference plane. When using cable assemblies or additional adapters, the device must be recalibrated according to the instructions. To calibrate the instrument, we recommend using ready-made calibration kits with N-type и SMA-type connectors.
To avoid premature wear of the instrument connectors, we recommend taking measurements with the screw-on adapters supplied.

1 The measurement is performed after warming up the instrument for at least five minutes with a full calibration. The change in ambient temperature from the moment of calibration to measurements should not exceed ± 3 ° С.

2 Where C is the speed of light m/s; VF – velocity factor (the ratio of the speed of propagation of electromagnetic waves in the cable to the speed of propagation of electromagnetic waves in a vacuum), takes a value from 0.1 to 1 (depending on cable); S - scanning frequency range (Hz).

Depends on the amount of attenuation in the cable and is the indication limit on the display.
