PRF Protection Limits
Table 31 PRF Protection Limits Considerations
Consideration Description
Maximum number
of Pulses/Sec
The number shown is both an upper bound on the PRF and a duty cycle limit when
DPRT mode is enabled.
Maximum
instantaneous
'PRF
Configure the maximum instantaneous rate at which triggers are allowed to occur, that
is, the reciprocal value of the minimum time between any 2 adjacent triggers.
This parameter allows you to limit the maximum DPRT trigger rate individually for each
pulse width.
Note that the maximum instantaneous PRF cannot be set lower than the maximum
number of pulses per second.
PRF limits: 50 Hz ... 20000 Hz
Maximum number of Pulses/Sec: 2000.0
Maximum instantaneous PRF' : 2000.0 (/Sec)
Range Zero
The range zero is the time at which the signal from a target at zero range appears at the
radar receiver outputs.
This parameter adjusts the delay from the active edge of the external trigger to range zero.
This delay must be correct when RVP900 operates with an external trigger, since the zero
range point is a fixed time oset from that trigger. When the transmitter is driven from the
internal trigger signals, the signals are adjusted to accomplish the alignment of range zero.
See 5.2.1 Mb — Burst Pulse and AFC (page 93) and A.12 Checking Burst Pulse and AFC with
Setup Mb Command (page 350).
Limits: 0.1 μsec ... 1000 μsec
External pretrigger delay to range zero: 3.00 usec
Range Resolution
The RVP900 range resolution is determined by the decimation factor of the digital matched
FIR filter that computes I and Q. This decimation factor is the ratio of the filter's input and
output data rates, that is, the output rate is some integer divisor of the IFDR Acquisition
Clock. See 5.2.2 Mc — Top-level Configuration (page 102).
