DFT using cadence spectre

Hi guys,

I am not familiar with DFT of calculator in cadence spectre.

The problem is in frequency domain i observe very low resolution and steps are 200Mhz !

how can i increase resolution ?

I have a 2.5 Ghz signal and i cannot observe it ! and neither other tones !

You just need to sample the signal from to to to+Nfft*Ts.
to = initial stabilization time
Nfft=point used for DFT measurement. It should be a power of 2.
Ts= The sampling rate of your system.
