DIY Multimeter High Frequency Signal Probe
Source: InternetPublisher:aerobotics Keywords: High frequency multimeter Updated: 2024/10/12
Ordinary multimeters can only measure signal voltages below audio frequency. However, this high-frequency signal probe uses voltage doubling detection to convert high-frequency signals into DC voltage and send it to the DC voltage block of the multimeter to measure high-frequency voltage signals. Toggle K to change the measurement range.
Circuit This additional device can be used with a multimeter to measure the high-frequency oscillation voltage of radios, televisions, wireless remote controls and other equipment. The probe housing should be made of metal. The output line should be shielded and should not be too long.
