If you have selected TAG inputs, then you have these options. The incoming TAG input bits
may be selectively inverted through each of the 16-bit words. The values are displayed in
Hex. Setting a bit causes the corresponding AZ (bits 0 ... 15) or EL (bits 16 ... 31) lines to be
inverted. Note that the SOPRM command also specifies TAG bits to invert. Both
specifications are XOR together to yield the net inversion for each TAG line.
The overall operations are performed in the order listed. Incoming bits are first inverted
according to the two 16-bit XOR masks. This yields an unsigned 16-bit integer value which is
then multiplied by the signed scale factor. The result is interpreted as a 16-bit binary angle
(in the low 16 bits), to which the oset angle is finally added.
TAG bits to invert AZ:0000 EL:0000
TAG scale factors AZ:1.0000 EL:1.0000
TAG offsets (degrees) AZ:0.00 EL:0.00
For example, assume the elevation angle input to RVP900 is in an awkward form such as
unsigned integer tenths of degrees, that is, 0x0000 for 0°, 0x000a for 1°, 0x0e06 for -1°,
and so on. If we apply a scale factor of 65536/3600 = 18.2044 to these units, we get 16-bit
binary angles in the standard format. If we further suppose that the input angle rotated
backwards, we could take care of this using a multiplier of –18.2044.
Co–Polarized signal is always on the primary Rx: Yes

Default receiver mode:0
The IFDR can operate in one of several fundamental modes for the acquisition of (I,Q) time
series data. See 7.2.2 RVP900 Receiver Modes (page 174).
You can select the receiver mode in the Mc menu, but changes only take
eect when you
save them and restart RVP900.
5.2.3 Mf — Clutter Filters
When a clutter correction is applied to the reflectivity data, you must increase the LOG noise
threshold slightly to continue to provide reliable qualification of the corrected values. The
reason for this is that the uncertainty in the corrected reflectivity becomes greater after the
clutter is subtracted away.
