Web24 jul. 2015 · It needs to have a 50 Ohm input and be able to work up to a high enough frequency. Stick a short piece of wire into the frequency counter's co-axial input socket and activate the transmitter nearby. You should get a decent reading. Now when i startup my remote and i keep it close to the wire, it reads 49.000.000 Hz ~ 50 Mhz. Web4. In general, to measure an output impedance, you just connect a known impedance across it and measure the drop in voltage level. You can then calculate the source impedance using the voltage divider rule. V out = Z 2 / (Z 1 +Z 2 )*V in. You know these:
