For whom?

The two-port vector network analyzer ARINST VNA-DL 1-8800 MHz is made in a plastic case in the form of a desktop device, designed to measure the parameters of various radio devices (antennas, filters, amplifiers, etc.) in the design and manufacture of telecommunications equipment. The device is ideal for workshops, radio amateurs, educational institutions, service centers. Requires a PC running Windows 7-10 to work. (Not included in the package).

Usage examples:

  • Make impedance matching using a Smith chart
  • Tune the antenna
  • Measure standing wave ratio
  • Measure the frequency response of passive and active devices
  • Measure the phase response of passive and active devices
  • Tune filters of the main selection, filters of the intermediate frequency
  • Measure attenuation in cable, microstrip line, waveguide
  • Measure the distance to the fault in the cable or its length

To calibrate the device, we recommend using ready-made calibration kits with N-type and SMA-type.
To avoid premature wear of the instrument connectors, we recommend taking measurements with the screwed-on adapters supplied.

Advantages of the ARINST VNA-DL 1-8800 MHz two-port vector network analyzer:

  • wide operating frequency range: from 1 to 8800 MHz
  • maximum scanning speed - 500 points / s
  • high precision in measuring the reflection coefficient: 0.25 dB and 0.7° in the entire frequency range
  • display of almost all possible interpretations of reflection coefficient and transmission coefficient
  • the ability to measure the distance to fault and loss in the cable
  • saving user presets and measurement results-traces (in Touchstone format)
  • power supply and control of the device via the USB port of the PC
  • low weight and dimensions: 250 grams , 155×127×29 mm

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

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

3Depends on the amount of attenuation in the cable and is the indication limit on the display.
