A. GS-320 Hand vector network analyzer VNA (reflectometer) 23 - 6200 MHz is designed to measure the matching characteristics of passive and active radio devices (antennas, cables, filters, attenuators, amplifiers, etc.). The device allows you to measure the parameters of the complex reflection coefficient, standing wave (VSWR), impedance, admittance, magnitude, phase, loss and distance to fault in the cable. B. GS-320 comes in a durable aluminum casing in the form of a mobile autonomous instrument. It is mainly intended to work directly on the object. With low weight and dimensions, it has low energy consumption. The analyzer can be useful to companies working in telecommunications, those engaged in the installation and maintenance of antennas, and in the amplification of cellular communication, etc. C. With it, service centers and repair crews can carry out RF analysis of cable and antenna during commissioning or repair work. Also, the device is suitable for workshops, radio amateurs, educational institutions and laboratories. The device has a 3.2 - inch color resistive screen to display the measurement results and control the device. For example, you can use the instrument to do the following: To perform impedance matching using the chart. To measure the standing wave. To measure the attenuation in the cable. To measure the distance to fault or irregularity in the cable. D. Advantages of vector network analyzer GS-320 23 - 6200 MHz: 1. A color touch screen with a diagonal of 3.2 inches allows for quick configuration of the parameters and display of measurement results. 2. Wide operating frequency range: 23 MHz to 6200 MHz. 3. A high rate of 1000 points/s. 4. High precision of measurement: 0.25 dB and 1.5 over the entire frequency range. 5. The ability to display up to four markers on all charts, allowing an accurate assessment of the measured parameter. 6. Display all possible interpretations of the reflection coefficient. 7. The ability to measure the distance to fault and loss in the cable. 8. Support for PC software, can be controlled through PC interface (The PC software can be obtained from dealers). 9. Small weight and dimensions: 480 grams with "pocket" dimensions 145x75x24mm. E. SPECIFICATIONS 23 - 6200 MHz: 1. Operating frequency range: 23 - 6200 MHz. 2. The frequency resolution: 10 kHz. 3.
