Vaisala RVP900 - Mf - Clutter Filters

Use external pretrigger : NO
PreTrigger active on rising edge: YES
PreTrigger is synchronous with IFD AQ clock: No
Answer the PreTrigger fires the transmitter directly sub-question
according to whether the radar transmitter is directly
fired by the external pretrigger, rather
than by one of the RVP900 trigger outputs. Answer YES if the transmitter can continue
running even if the RVP900 TRIGIN signal is 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 is aected rather than the start times of the six output
triggers.
PreTrigger fires the transmitter directly: NO
Output Triggers
The number of user–defined output triggers is limited to 12 (including polarization output
controls).
Number of user–defined output triggers: 6
Polarization Output Controls
The next setting
defines the number of polarization output controls.
Number of polarization output controls: 2
Blankable Triggers
Modify the next setting to reduce erroneous transmissions into physical obstructions.
RVP900 can inhibit the subset of blankable trigger lines when a noise measurement is
taken. This is forced when trigger blanking (based on TAG0) is enabled, but it can also be
selected in general through this question. Since noise triggers must be blanked when trigger
blanking is enabled, this question only appears if trigger blanking is disabled.
These settings permit the state of the triggers during noise measurements to be consistent
and known, regardless of whether the antenna is in a blanked sector.
