I am simulating a special configuration of a Colpitts oscillator based on a
NPN BJT. I just wanted to know how I can use QUCS to measure the frequency
of the output signal.
Thanks for any reply,

Hm. Probably I think too complicated... but this is my suggestion:
1. simulate oscillator in time domain using transient simulation
2. setup equations for freq. measurement:
"freq" should then contain the frequency value for the maximum peak
in the spectrum of the ouput time domain signal...
Hope this helps, Stefan.
