Attachment preparation before IQ2011 wireless comprehensive tester test
(1) Regulated power supply. Users need to measure the radio and walkie-talkie. In order to get accurate and stable power reading, it is required to use external regulated power supply. This can eliminate the large current output voltage change caused by insufficient battery capacity or aging, which directly affects the power output. . To this end, the IQ2011 wireless integrated tester needs to be a different type of hand-held walkie-talkie for each model of the borrowing board, if there is no salt, you can use the battery box to modify.
(2) Test the cable, including RF cable and audio cable. The RF cable should be a product with low attenuation and soft body. The cable should not be too long or too thin (usually require high quality and low loss -5 or -7 cable or special test cable). The type of connector at both ends of the cable should be The integrated tester and transmitter antenna ports are matched to minimize the use of adapters to reduce insertion loss. The audio cable is primarily used to input the receiver's audio signal into a comprehensive tester to determine the actual sensitivity of the receiver at a specified signal-to-noise ratio. Another major function of the audio cable is to input the standard audio signal output by the integrated tester into the transmitter's microphone to detect the modulation characteristics of the transmitter. Audio test cable If there is no ready-made product, the IQ2011 wireless integrated tester can be made with a thin cable with a shield structure, or with a headset microphone for the walkie-talkie.
