Hi

I'm trying to make measurement of MER value of a DVB-C source (setup: QAM16, symbol rate 6.9 Msymbol/s, center frequncy 850MHz, bw 8MHz ). I have measured the MER value with an other instrument (R&S EFA) which measure 42dB, but with my EXA with the VXA sw i'm only able to measure 29.4dB.
My questions are:

Is a MER value of 29.4dB the limit of the instrument?
Is it a mean value or a minimum value the instrument outputs?
