Linearized saturation headroom: 4.0 dB
Amplitude Correction
RVP900 can perform pulse–to–pulse amplitude correction of the digital (I,Q) data stream
based on the amplitude of the Burst/COHO input. See 7.2.7 Amplitude Correction for Tx
Power Fluctuations (page 182).
Limits: 10 pulses ... 500 pulses
Apply amplitude correction based on Burst/COHO: YES Time constant of mean
amplitude estimator: 70 pulses
Channel Separation
The following parameters appear if you select WDR in the Mc (see 5.2.2 Mc — Top-level
Configuration (page 102)).
You must determine the Channel separation and Overlap/Interpolate
interval from the Pr printout. Sweep a signal generator across the shared power region
of the two channels to determine a representative channel separation, along with the size of
the overlap region at the top of the HiGain channel within which that separation remains
steady and constant, that is,
unaected by eventually approaching the noise floor of the
LoGain channel.
RVP900 continually measures and updates the complex channel separation during normal
operation. Ratios of echoes that fall within the overlap/interpolate interval are averaged
over several minutes, tracking gain and phase variations that occur with temperature
changes and component aging. If the channel separation ever exceeds the
specified
maximum deviation, the GI4S_IFDCHANERR bit (11) is set in GPARM Immediate
Status Word #4.
IFD Wide Dynamic Range Parameters Channel separation: 20.00 dB, 0.0 deg
Maximum deviation : 0.50 dB, 5.0 deg Overlap/Interpolate interval: 30.00 dB
Interface Filter and Unfolding
RVP900 can optionally apply an interference filter to remove impulsive-type noise from the
demodulated (I,Q) data stream. See 7.2.5 Interference Filter (page 178).
