Economical Practical Transmission Power Test Pen ----- Transmission Power Tester

Economic Practical Transmission Power Test Pen, Transmission Power Tester Keywords: transmit signal strength tester, transmit power tester I have been engaged in radio communications in 1981. According to work practices in more than 20 years, some test tools have been made, and there is an effective handheld walk-in-talkation power test pen circuit as shown in Figure 1. If it is installed in the test pen of a million meter, as long as the pen is close to the top of the handheld walkie-talkie launch antenna, it can accurately determine whether the walkie-talkie has no power emission, and can be based on the lighting The degree of light of the diode, rough judgment the size of the transmit power, and the production cost is not more than one yuan. Further, on the basis of the circuit diagram 1, it is changed to FIG. 2; that is, the light emitting diode is removed, the DC2.5-1OV block of the A, B, and the DC2.5-1 OV block of the digital multimeter is measured, and the vehicle radio or handheld walk-in-law power amplifier level is measured. Each promotion level test point is to determine which level of failure, this is what the power meter cannot be done. After long-term work practice, I think this is a good tool for repairing walkie-talkie.
