Signal Tracer Circuit Diagram. The complete circuit of the project. The signal tracer rf and audio probe using lm386 integrated circuit is geared towards maintaining preamplifier power amplifiers and even rf devices.
Now you can detect or inject a signal at certain points of the circuit e g. Ic1 consists of two operational amplifiers which get operated from a single power source with a wide voltage range form 3v to 32v. The circuit uses two ics.
The signal tracer rf and audio probe using lm386 integrated circuit is geared towards maintaining preamplifier power amplifiers and even rf devices.
It also needs to have high input impedance so it doesn t load the circuit under test. The tracer amplifier needs lots of gain and a gain or volume control is essential. Circuit diagram with parts list. It also needs to have high input impedance so it doesn t load the circuit under test.
