Actually I'm using Vector signal generator 2920 and Vector signal analyzer 2820 along with signalmeister software, I want to generate single  carrier signal (PSK) using my program which I simulate in matlab, first I loade it to IQ import then convert it to arb file then send it VSG 2920,I'm adjusting the sample rate in IQ import as I have in my matlab program ,lets say I'm using pulse shaping filter (RRC) with oversamling=5MHZ,so i'm adjusting the sample rate in IQ import to 5MHZ but I have aproblem.
The problem is ,I'm not getting the right bandwidth which supposed to be 2*(1+alpha/2*Ts),I don't know why????
I guess my procedure is right ,and my propram in matlab run succesfully,do you have any idea behind this wrong bandwidth?
Thanks,
