GS-320 handheld vector network analyzer VNA (reflectometer) 23-6200MHz is designed to measure the matching characteristics of passive and active radio equipment (antennas, cables, filters, attenuators, amplifiers, etc.).

This device enables you to measure the parameters of complex reflection coefficient, standing wave ratio (VSWR), impedance, admittance, amplitude, phase, loss and distance to cable fault point.

GS-320 is made of durable aluminum shell and adopts the form of movable automatic instrument. Because of its light weight, compact structure and low energy consumption, it can directly measure the object to be measured. This analyzer is especially suitable for companies engaged in the field of telecommunications, antenna installation and maintenance, and cellular communication amplification. With it, service centers and maintenance personnel can perform RF analysis on cables and antennas during commissioning or maintenance work. In addition, this equipment is ideal for workshops, radio enthusiasts, educational institutions and laboratories.

The device has a 3.2-inch color resistive screen that can display measurement results and control the device. For example, you can use the instrument to perform the following operations:

- Use Smith chart for impedance matching

- Measure standing wave ratio

- Measure the attenuation in the cable

- Measure cable faults or irregular distances

Note:

1. Warm up the device for at least five minutes, and perform the measurement after complete (short-circuit, disconnection, load) single-port calibration. The ambient temperature change from calibration to measurement must not exceed ±3°C.

2. Where C is the speed of light m / s; VF is the speed factor (the ratio of the propagation speed of electromagnetic waves in the cable to the propagation speed of electromagnetic waves in vacuum), and the value is 0.1 to 1 according to the cable; S is the scanning frequency range in the frequency task (Hz).

3. It depends on the attenuation of the cable, which is the limit displayed.

4. After fully charged, add 20±5°C to the ambient temperature. The device has been factory calibrated and the device connector is used as a reference. If you plan to use cable assemblies, adapters, etc. for measurement, you need to recalibrate. For this, please use the 50 ohm calibration kit SOL (S-short circuit, O-open circuit, L-load). SOL calibration kits are most commonly found in N-type and SMA-type form factors. On the reference of the planned calibration, select the outline size corresponding to the connector type.
