4.3-inch IPS LCD screen, IPS TFT (800x480) viewing angle close to 180, long-term use without hurting the eyes;The aluminum alloy casing is used to effectively shield electromagnetic interference, making the dynamic range of S21 80dB within 1GHz. Compact design, body size 125mm x 75mm x 20mm, compact and portable;The RF interface is SMA, which is convenient for connecting various DUTs; Full touch screen design, supporting 3 side buttons at the same time, flexible and convenient operation; Measurement frequency range: 50KHz-3000MHz;RF output power: -9dbm (error within 1GHz: plus or minus 1db);Frequency accuracy: Less than 0.5ppmS21 dynamic range: 70dB (1.5GHz), 60dB (3GHz). S11 dynamic range: 50dB (1.5GHz), 40dB (3GHz). 2-port return loss: 20dB typ (1.5GHz), 13dB min (3GHz). USB Interface: USB Type-C Communication Mode: CDC (Serial). Number of calibration points: 201 points. Number of scanning points: 201 points. Display traces: 4 traces Mark: 4 mark points (the mark bar can be dragged anywhere on the screen) Setting saving: 8 (after saving, it can be called directly when starting up time, no need to re-calibrate, and the saved parameters before the last shutdown will be automatically recalled when starting up time, and the function of automatically storing the start and stop frequency is added, which is convenient for the call) Scanning time: about 1.9s/1 time (50kHz ~ 3000MHz full frequency band) Can measure S parameters, voltage standing wave ratio SWR chart phase diagram, group delay, TDR function...; Using 5000mAh ultra- capacity lithium battery, the battery life can reach 7 hours; Support Chinese and English menu switching; Support screen brightness adjustment; Upgrade the firmware through a virtual U disk, without a programmer, and only need a USB cable to upgrade the firmware; Expand a USB power output interface, 5V/1A output (can be used as a power bank); Using a high current 2A charging IC, the charging time is shorter; Support the upper computer, you can use the computer as the display operation interface; Colour:black Material:aluminum alloy Package Contents: 1 x host 1 x SMA open circuit calibration kit 1 x SMA short calibration kit 1 x SMA 50ohm load calibration kit 1 x SMA- double-ended female adapter 1 x SMA-JJ double-ended male pin adapter 1 x SMA-JKW Elbow Outer Thread Inner Hole to Inner Thread Inner Needle Adapter 2 x RF cables 1 x type-C data cable 1 x stylus Only the above package content, other products are not included.
