Support a variety of high-speed dynamic acquisition, support spectrum display, can accurately measure single-frequency RF power;. Built-in digital programmable attenuator (O-31.75DB), with numerical control attenuator in the case of measuring the maximum input power of 30dBm(1W), dynamic range: +30dBm to -70dBm. RF power meter V10 comes with 1.3 inch TFT LCD and built-in Li battery, can run offline (spectrum). The upper computer has two MARK cursor function, easy to measure the modulation pulse width; Automatically find the maximum value, minimum value function. Boot process: check whether the battery switch needs to be ON position, and then the middle button of the panel. 1, measuring power range -70 ~ +30dbm (0 to -40dbm has a good linearity, input signal 0 to +30dbm, must set the internal numerical control attenuator ATT=30DB, OFFSET=+30DB measured after the display of the measured power value 2, measuring power resolution 0.1dBm 3, measurement frequency range 35M ~ 4.4GHz(different models frequency range is different) 4, input impedance: 50 5, dynamic range: 100dB 6, working voltage: 5VDC(through the TYPE-C line power supply) 7, charging current: 400mA Colour: Silver Material: Aluminum Alloy Package Contents: 1x RF Power 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.
