The Signal Quality Index (SQI) threshold is an unsigned binary fraction in
the range 0 to 255/256. When the SQI for a range bin falls below the stated
value, it may result in thresholding of data. An analogous Polarimetric
Meteo Index (PMI) can be set by the command THRESH (see Section 7.29
Set Individual Thresholds (THRESH) on page 329).

Weather Signal Power (SIG) is an estimate of the SNR of the weather
component of the received signal. When the SIG (see Section 6.3.8
Weather Signal Power (SIG Threshold) on page 223) falls below this
comparison value it may result inthresholding of data.

The calibration reflectivity is referenced to 1.0 kilometers.

The TopMode bits select the overall data acquisition and processing mode
for the RVP900. Although the processing algorithms that are used in each
top level mode are quite different, the RVP900 command set works in a
uniform way in all modes.
0000 Polarimetric Processing or PPP Mode is a combined time
domain and frequency domain approach that is used
primarily for dual polarization applications; data are
processed in batches of pulses (see Section 6.2 Time Series
(I and Q) Signal Processing on page 195).
