As an example, suppose that the elevation angle input to the RVP900 was
in an awkward form such as unsigned integer tenths of degrees, i.e.,
0x0000 for zero degrees, 0x000a for one degree, 0x0e06 for minus one
degree, etc. 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
too 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. For details, seeSection 6.1.2 RVP900
Receiver Modes on page 185.

Default Spectral Window- 0:User, 1:Rect, 2:Hamming,
3:Blackman : 0
Whenever power spectra are computed by the RVP900, the time series data
are multiplied by a (real) window prior to computation of the Fourier
Transform (DFT). You may use whichever window has been selected
through SOPRM word #10 "0:User", or force a particular window.
In case of IRIS application, the setting "0:User" refers to the window
defined in the Setup Utility block RVP "Signal Processing Options". In
case of ascope application, the setting "0:User" enables the button "Spect
Win". At RVP900 startup, "0:User" refers to the settings saved in
rvp9.conf block 'opprm.filter' bits 9,10,11.
Allow continuous sizes for power spectra: YES
The power spectra computed within the RVP900 are normally not
constrained to be powers of two in length. However, answering NO re-
applies that constraint to mimic the behavior of older processors
NOTE
The receiver mode is chosen in the Mc menu, but changes do not take
effect until they are saved and the RVP900 is restarted.
