multisim too slow Fourier transform

[MAJDGH]

Hello everyone

I am simulating a high frequency circuit and I want to know all of the harmonics in the signal and if I put a lot of of harmonics in Fourier analysis it is taking too long time to finish analysis and sometimes it doesn't finish at all

we are using ORCAD with PSPICE FFT (Fast Fourier Transform) in college and with one click we see the output harmonics

But I prefer to use multisim so for many reasons

anyway is there any way to speed Fourier transform in multisim

my settings is :

fundamental frequency is 10 KHz

number of harmonics is 13000 (big number)

so to reach 130 MHz

and bytheway for these settings i want more for example :

fundamental frequency is 1 KHz

number of harmonics is 130000 (big number)

Dear MAJDGH,

Thanks for posting your question.

Could you please create a measurement in both Multisim and also in ORCAD with the same parameters. It should be a measurement that definately finisihes in Multisim. This way we could check if both programs return the same results. 

Good luck, I am looking forward to your reply,

Tamas
