Handheld Vector Network Analyzer VNA (Reflectometer) 23-6200 MHz is designed to measure the matching characteristics of passive and active radio equipment (antennas, cables, filters, attenuators, amplifiers, etc.) The device allows you to measure parameters of complex reflection coefficient, standing wave ratio (VSWR), impedance, admittance, amplitude, phase, loss and distance to cable fault points The device has a 3.2-inch color resistance screen to display the measurement results and control the device a aluminum housing, in the form of a mobile automated instrument, it can be measured directly on the object to be tested because of its light weight, compact structure, low energy consumption The analyzer is particularly suitable for companies working in the telecommunications field, antenna installation and maintenance, cellular communication amplification, etc Operating frequency range: 23-6200 MHz Frequency resolution: 10 kHz Maximum number of sweep points: 1000 Sweep speed: 1000 points/sec Direction of , uncorrected over the entire range: 12 dB Effective directivity (after full one-port calibration): 50 dB VSWR at input: less than 2 Phase measurement accuracy: 1.50 Amplitude measurement accuracy: 0.25 dB Resolution for determining distance to fault: (C x ) / 2S m Maximum length of measurement cable: 3000 m ( = 1) Maximum DC input voltage: 25 V Displays: chart; plot; Phase of reflection coefficient; Amplitude; Logarithmic magnitude; VSWR, distance to fault; Cable loss Operating temperature range: 0 -40℃ Screen diagonal: 3,2 inches Screen type: resistive Screen resolution: 320x240 Battery capacity: 4000 mAh Battery life: about 4 hours Battery charging time: about 6 hours Colour:As Shown Material:ABS Package Contents: 1 * Vector Network Analyzer Kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
