Hi,
I have N5182A with N7623B with which I have generated a wave file DVB-T :
Fec : 1/2
Costellation : 64QAM
OFDM : 8K
Guard 1/32
With null packet loop file.
I made the internal IQ calibration and I have connected N5182A to MXA9020 with N6153A DVB-T/H Measurement Application and I obtain this :

Why pilot BPSK is out of reference circle ?
Thanks very much.

I asked an Agilent support engineer to take a look at this. Here is the reply:
+This point is not a correct one. It may be caused by feed through of MXG. Please do DC calibration first, then try again. Or on SA side, turn off carrier 0 (start from carrier 1).+
I hope this helps -
