Feature:1. [FOR RADIO EQUIPMENT] Used to measure the matching characteristics of passive and active radio equipment, such as antennas, cables, filters, attenuators, amplifiers, etc.2. [WIDE FREQUENCY RANGE] 23MHz to 6200MHz wide operating frequency range, full frequency range 0.25 dB and 1.5, to achieve high accuracy measurement.3. [3.2IN TOUCH SCREEN] With 3.2in color touch screen, can quickly configure scan parameters and display measurement results, scan speed up to 1000 points/sec.4. [INDEPENDENT MARK] Ability to display up to 4 independent markers on all graphs for accurate evaluation of measured parameters.5. [MULTIPLE DISPLAYS] Can display almost all possible reflection coefficient descriptions, measure cable faults and loss distances.6. [WIDE APPLICATION] The vector network analyzer VNA is very suitable for radio frequency circuit matching and debugging of Bluetooth, WiFi, 2.4G, 5.8G, and GPS.7. [ALUMINUM ALLOY] The shell is made of aluminum alloy and adopts the form of a mobile automatic instrument, which is light in weight and compact in structure.Specification:Item Type: Vector Network AnalyzerMaterial: Aluminum AlloyColor: BlackModel: GS-320Operating Frequency Range: 23-6200MHzFrequency Resolution: 10kHzMaximum Scanning Points: 1000Scanning Speed: 1000 points/secBridge Direction, Uncorrected in the Entire Range: >12dBEffective Directivity (after Full Single Port Calibration): >50dBStanding Wave Ratio at the Input: <2Phase Measurement Accuracy: >1.5 degreesAmplitude Measurement Accuracy: >0.25dBResolution to Determine the Distance to the Fault Point: (C x VF) / 2S mMeasuring Cable Maximum Length: Approx. 3000m / 9842.5ft (VF=1)Maximum DC Input Voltage: 25VDisplay Chart: Smith chart; polar chart; phase of reflection coefficient; amplitude; logarithmic amplitude; VSWR, fault distance; cable lossOperating Temperature Range: 0-+40Screen Diagonal: 3.2 inchesScreen Type: Resistive touchScreen Resolution: 320240Battery Capacity: 4000mAh lithium battery(built in battery)Battery Life: ~4 hoursBattery Charging Time: ~6 hours.Package List:1 x Network Analyzer1 x Type-C Data Cable1 x Touch Screen Pen1 x SOL Calibration Part3 x Adapters1 x English User Manual
