Short wave HF band 150W power standing wave meter CP version. Description: 5 interface display modes. Dynamic simulation display bar. Switch between normal mode and hold mode. According to the fitting algorithm of detector diode characteristics, the accuracy is 5%. High-speed average detection mode, real-time efficiency display. The standing wave is 2.0 intermittent beep alarm, and the standing wave is 3.0 continuous beep alarm. It is compatible with g8gyw software code, and free code modification brings more . Built-in lithium battery can be used for more than 50 hours at a time. Parameters: Frequency range: 1.6-50MHz Power measurement range: 0.5W-150W Standing wave measurement range: 1.0-99.9 Insertion loss: Less than 0.12dB Insertion standing wave: 1.6-30MHz 1.02; 30-50MHz1.05 Measurement accuracy: 5% Impedance: 50 Standing wave alarm: 2.0 intermittent alarm, 3.0 continuous alarm (with shutdown function) RF interface type: SL16-M Display content: forward power; Standing wave; Antenna power; Efficiency. Power supply: built-in 3.7V/900mAh rechargeable lithium battery or USB type-c Shutdown power consumption: Less than 0.1uA Screen size: 0.96 inches; Screen type: OLED Data communication: USB type-c Overall size: 88mm x 38mm x 64mm (excluding protruding part) Special reminder: the above parameters have been measured by professional instruments and are true and effective. 150W continuous detection; More than 500W will damage the detection components. Brief introduction: Long press on/off, short press on/off to switch the display interface, and double click on the switch for standing wave alarm; Three-click to switch between normal mode and hold mode. There are 5 displayinterfaces in total, which are automatically saved and called automatically time. The charging red light shows that the light is off when it is full. Color: As Shown Material: metal Package Contents: 1 x Short wave standing wave meter 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.
