Data Source in EXG5172B

Discussion created by jshyanki on Sep 30, 2020

Hi

 

I am trying to test my QPSK Demodulator using EXG 5172B equipment by setting as a QPSK modulator.
at symbol rate of 2.31 MSPS.
I need following information of modulator. So that i can compare that data source whether it is correct of not.
1. If i select data source i internal PN-9 sequence. what is polynomial and seed of PN generator?
2. Differential encoding is done in IQ level or bit level?
3.  What is default filter? I mean if it is in Nyquist does it mean that it is RRC or SRRC filter?
