oscillator jitter measurement(jc , jcc)

Hai sir,

        I am simulating the LC VCO at a free running frequency of 5GHz. 

PSS settings: Beat frequency - 4.5GHz, number of harmonics - 10, tstab=100n

pnoise settings: pss beat freq - 4.5GHz, sweep type - relative, sweep range 100k to 2.5GHz, max sidebands -10, noise type-jitter 

are the above pss and pnoiose settings correct

I am getting the phase noise of -78dBc/Hz at 1MHz offset. the measurement of jitterjc gives 157fs 

for measuring jcc what  must the value of k.

Is the setting noise type-jitter correct, if it is wrong which one we have to choose(source, modulated).

please help

thank you 

satya
