in the presence of a strong test signal. Since "I" and "Q" are inherently
balanced in the RVP900, these output words are no longer of much value.

The noise standard deviations for each receive channel are normalized to
the mean power. The values reported here hover around 0 dB for ordinary
exponentially distributed noise in which the standard deviation scales
directly with the mean.
0916-136
Inter.F Specifies which interference filter is running.
Zero means "none"; see Section 6.1.5
Interference Filter on page 189 for a
description of the interference filter algorithms.
MinRev Minor revision level of the RVP900 code that
is currently running
IFDR Sat.Power
( P
MAX
)
Input power required to saturate the IF-Input
A/D converter for the IFDR that is currently
