Hi All,
To do this I used a Complex to Mag^2 block, into a probe, giving a normalized received power from UHD. I then use this as part of an 'if' statement in the Textbox showing EVM, like
"float('Inf') if UHD_Probed < 1e-6 or UHD_Probed > 2e-3 else EVM_Probed"
This is a slight hack, and involves setting thresholds, but it works for what we need!
Cheers,
David

I am showing EVM (a block we have written) in a text box using a probe signal, in an OFDM system based on MB's OFDM example.
this works fine when packets are being received, but I would like to show 0 when no packets are received (no items coming through HPD), rather than just the EVM calculated based on the last *received* packet.
Thanks for your help!
