Limits: 0 to 3
Use external pretrigger: NO
PreTrigger active on rising edge: YES
PreTrigger is synchronous with IFD AQ clock: No
PreTrigger fires the transmitter directly: NO
When an external pretrigger is applied to the TRIGIN input of the
RVP900, either the rising or falling edge of that signal initiates operation.
This decision also affects which signal edge becomes the reference point
for the pretrigger delay times given in the Mt<n> section.
Answer the second sub-question according to whether the radar transmitter
is directly fired by the external pretrigger, rather than by one of the
RVP900 trigger outputs. In other words, answer "YES" if the transmitter
would continue running fine even if the RVP900 TRIGIN signal were
removed. This information is used by the L and R subcommands of the Pb
plotting command, that is, when slewing left and right to find the burst
pulse, the pretrigger delay will be affected rather than the start times of the
six output triggers.
Number of user–defined output triggers: 6
This setting defines the number of user–defined output triggers.
Limit: 12 (including polarization output controls)
Number of polarization output controls: 2
This setting defines the number of polarization output controls.
Blank output triggers within AZ and EL sectors: NO
These settings can be modified to reduce erroneous transmissions into
physical obstructions.
Blank output triggers during noise measurement : NO
