Can this be displayed in Spike? Will the symbol rate drop down menu go up to 12.5Ms/s? I am anticipating buying the Bb60c of it can display there’s higher data rates in Spike. I need an constallation and eye pattern display for my customer.
Thanks for all your help
Phil

Hi all
I set up a spreadsheet to convert EVM to BER for QAM modulation. works from M=2 to M=1024 very reliably. The file is attached.

I have been using the ZFDC-20-5+ by MiniCircuits for several years. It is good from 100kHz to 2 GHz. Attached are some VNA plots I took. Works great with the tracking GEN. Above this freq I use Narda transmission line couplers. They are a little bit more expensive.
