Using this automatic probe, you can see measure both audio signal (AF) and radio signal (RF). If audio signal is being measured, the path of the signal is via C1. Audio signal can’t pass the C2 since the capacitance is very small and having very high impedance for audio frequency signal. If you measure high frequency (radio frequency, RF), now […]

This is Attenuator Pads circuit. This circuit can be used when testing wireless network links to help simulate real life signal loss. This circuit can handle DC – 18 GHz, 2 watts of power, and have built in SMA connectors. The attenuator pads can be combined to increase the overall attenuation. a long length of high-loss cable, such as RG-174 […]
