Features: 4.3-inch IPS LCD display, resolution 800*480, ultra-wide viewing angle, long-term use does not hurt your eyes. All aluminum alloy case, effectively shielding electromagnetic interference to ensure measurement accuracy. The radios frequency interface is SMA, which is convenient for connecting various tested parts. Full touching screen design, with 3 side buttons at the same time, flexible and convenient operation. Support Chinese and English interface. Optimized UI design, convenient for users to perform measurement operations. Support screen brightness adjustment. The firmware can be upgraded through a virtual U disk, no programmer is needed, and the firmware can be upgraded through the included USB type-c data cable. Standard fine quality calibration parts and RG405 phase-stable cable to ensure calibration accuracy. Designed with USB power output interface, which can support 5V/1A power output. Using 2A high current recharging IC, the recharging time is shorter. Supporting host computers software, the host computers supports Chinese and English interfaces. The screen images of the device can be obtained by taking a screenshot of the host computers. Function: can measure S parameters, voltage standing waves ratio, Smith chart, phase, group delay, etc. Specifications: Material: aluminum alloy(case) Main color: black Battery: 1 * lithium battery, 5000mAh Frequency: 50kHz-3GHz RF output power: -9dBm (error within 1GHz: ±1dB) Frequency accuracy: <0.5ppm S21 dynamic ranges: 70dB (1.5GHz), 60dB (3GHz) S11 dynamic ranges: 50dB (1.5GHz), 40dB (3GHz) 2-port return loss: 20dB typ (1.5GHz), 13dB min (3GHz) Number of calibration points: 101 points Number of scanning points: 101 points Number of traces: 4 Number of mark points: 4 (the mark point bar can be moved up and down on the screen) USB interface: USB Type-C communication mode: CDC (serial) Setting save: 5 groups (after saving, it can be directly recalled when it is used again, no need to recalibrate, and the saved parameters before the last shutdown will be automatically recalled when it is turned on again) Support calibration results interpolation, can measure without recalibration after adjusting the measurement frequency band Scan time: about 1.9s/1 time (50kHz~3000MHz full frequency band) Item size: 140 * 73 * 20mm / 5.5 * 2.9 * 0.8in Item weight: 270g / 9.5ounce Packing size: 250 * 150 * 50mm / 9.8 * 5.9 * 2.0in Packing weight: 507g / 1.1lb Packing List: 1 * Host 1 * SMA Open Calibration Kit 1 * SMA Short-circuit Calibration Kit 1 * SMA 50Ω Load Calibration Kit 1 * SMA-KK Double Heads Female Hole Adapter 1 * SMA-JJ Double Heads Male Pin Adapter 1 * SMA-JKW Elbow Outer Screw Inner Hole To Inner Screw Inner Adapter 2 * 200mm SMA-JJ RG405 RF Cable 1 * USB Type-C Data Cable 1 * Styluss    By the way,if you like our store,please add our store to your Favorite Stores.You can get our New arrival and Discount  information in time.
