Re: Digimess SG100 RF Signal Generator. 100 KHZ to 150 MHZ
What is the fault, what are the symptoms?
I have a Digimess SG100, bought brand new from Digimess. I had no 1kHz modulation signal, the trimmer on the pcb needed tweeking to get the op-amp to oscillate. If I tune a radio to pick up the signal and tap the SG100 case the signal sounds "microphonic", have yet to discover which component, have gently tapped every component in turn with no luck. I have a circuit diagram if that is of use. |
