Hi all
A project I am working on at the mo uses a 1MHz pulse train of 1% duty cycle to switch on and off a carrier of the order of 6GHz. I have been able to recover the sinc spectrum of this signal on a hp8562a spec an. The recovered P.S.D trace is made up of 601 data points. From this trace I was hoping (by the use of the inverse fft function) to recover the time domain pulse so as to measure its rise time, fall time, width etc. I was hoping someone had tackled a similar problem before.
Is what I am trying to do at all possible from a simple PSD trace?
If so should I use the real or complex inverse fft function?
Can I recover a time axis without any phase info?
I know I ask a lot but am under pressure for time and a
ny help would be much appreciated, no matter how small!
P.S I am working with LV 6.02, win XP and talking with spec an using GPIB.
