Vector error is the same as SNR, but probably expressed as a negative rather than positive dB value. Also it is an actual SNR calculation from comparing the received constellation point to the decoded constellation point which is presumably what was originally transmitted. As opposed to inferring SNR from bit error rate.

Sorry, too easy to pass up. Vector Error: The vector error measurement compares the received signal's In phase /Quadrature (IQ) modulation characteristics to an ideal signal to determine the composite errorvector magnitude. The results are stored in a histogram and expressed in dB and presented as: max, mean, min and latest. The expected range for Vector Error would be approximately 0dB (NLOS link operating at sensitivity limit on BPSK ½) to –29dB (short LOS link running 64QAM 7/8) That's straight from Motorola PTP 400 Series User Manual Page 73 that I found by searching Google for "PTP400 Vector Error." Hope that helps. -Ty On Wed, Oct 14, 2015 at 2:07 PM, Dan Petermann <[email protected]> wrote: What does vector error indicate? -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
