100KHz-1000MHz/1GHz Field Strength Indicator Meter RF Signal Level Tester + Antenna

Feature 1 Simple and efficient appearance beautiful and generous2 Wide frequency band high sensitivity 100KHz 1000MHz the original antenna is 400 470Mz test signals of different frequencies please use antennas of different frequencies to have better results and sensitivity 3 Adjustable pointer amplitude to protect the watch head 4 Built in automatic damping function that is buffer function to prevent the watch hand from swinging too fast to cause damage5 Small size easy to carry6 Test sensitivity 1 0 1W transmitter from 0 1 1m 2 2W 5W transmitter 1 3 m range 3 10W transmitter from 2 5 m range 4 50W about 3 10m rangeWith HP8921A radio comprehensive tester test sensitivity of 20dbm just start the table 2dbm can be full table different frequency sensitivity will be different Instructions for use Before use please rotate the amplitude adjustment to the leftmost end the length of the antenna should be determined according to the frequency of the test as far as possible 1 4 wave is better the handheld walkie talkie is about one meter away from the field intensity meter do not be too close Lest the signal is too strong to burn the field intensity meter Then press the walkie talkie PTT button to make the walkie talkie enter the transmitting state at this time the pointer of the field intensity meter should indicate the signal the stronger the signal the greater the indication Amplitude adjustment If the pointer of the field intensity mete
