2005年11月12日 · I came across this signal tracer with no probes. The audio is a simple probe, but the RF probe has a 470 K ohm 1/2 watt resistor and a IN48 germanium crystal rectifier diode. The resistor is no problem, but where can I get the diode to build this probe. Or, is there a better solution in a probe I can buy?<BR>Thanks,<BR>Don <P>-----<BR>

Most signal tracers use a germanium signal diode in the probe for demodulating radio frequency signals. That's a bit like a crystal radio without its tuning elements but amplifying the audio to a speaker level. A switch to bypass the diode or use of a separate probe selects audio tracing.

2013年6月21日 · Here's how it's used: when troubleshooting an amp, inject a signal into the input f the amp (or into a subsequent gain stage). Use the probe on the signal tracer and just touch different components down the signal path. If you don't hear the signal at one point, you've just found the problem, it's just before where you stopped hearing the signal.

2016年8月20日 · Essentially, the common signal tracer design such as this EICO 147 is just a high gain audio amplifier with an input for audio signals through a pair of straight wire probes. For "listening in" on the radio frequency signals, there is provided a demodulator probe with a shielded cable that connects to the RF input.

2024年7月3日 · It has been recapped in several new resistors. All tubes are good, right down to the magic eye, new power cord. And you even get the Eico model 147 signal tracer probe with the IN48 detector diode and 490,000 resistor. Usually you never get the probe. Unit works great.
