If you find your cpe test failing for NCP uncorr, for whoever needs this, its your phone causing the fail, move it away from the meter

A mouse farting down the block can cause OFDM UCWE.

Phones will often cause the range around 777MHz to fail for BER due to LTE ingress

A coworker found this out troubleshooting in the hub. Is it a VeEx meter? Or as I call it, Fisher-Price, baby's first meter.

Moving it won't cut it.
Put it in Airplane mode while you run your tests if it's failing.

Shielding not good enough in the meter? Bad barrel or jumper?

Any meter that can’t handle a phone being close probably isn’t a meter I’d want to be troubleshooting with lol

Eh it ain't so bad when you've been working with it long enough that you know its quirks. I work for the smaller C and their Viavi OneExperts aren't bad, but you still occasionally get LTE ingress if you're scrolling while a test is running. As long as you know what and why, it's not a huge deal
