How to set a tracker?
Find out the input frequency with a spectrum analyzer
Turn on the tracker

(K+K counter and tracker have different pin assignments !)
Turn the gain down to 0
View the monitor output or A/B output frequency on the spectrum analyzer (Maybe too strong signal, dBm)
Turn the frequency by means of the VCO rotary knob to the required frequency
Now plug in the RF signal in the RF signal input
Turn the gain up until you can see a better signal
Done
Controversial discussion: Some people use the integrator and some people not. Usually we don´t use the integrator. If you want to use it, aktivate the integrator after step 7).
