RP[N] - Recorder Parameters
Purpose:
Enables the complete specification of how the recorder is triggered and how the
recorded data is transferred to the host.
Trigger definitions:
The recorder is started by a trigger event, which may be one of the following:
Immediate:
The recorder starts immediately after the recording request has been issued.
Triggered by an analog signal:
The recorder starts upon one of the following events:
Positive slope: The signal crosses a prescribed level with a positive slope.
Negative slope: The signal crosses a prescribed level with a negative slope.
Window: The signal exits a window of two prescribed signal levels.
Digital inputs: Digital inputs are switched to their active logic state as defined by
the IL[N] command.
Motion begins:
A BG command, or the activation of a hardware BG command (refer to the IL[N]
command).
Trigger delay:
The trigger defines when the recorder is to start. The recorder can be programmed to
start before the trigger event, so that the trigger event can be caught “in the middle of
the action.” This is possible because the recorder starts to record at the instant it is
launched by the RR command, so that when the trigger event occurs, the pre-trigger
information is already recorded. The trigger parameters are listed in the following
table:
RP[N] Range Definition
RP[0] [0…1] 0: Time quantum is 4*TS
1: Time quantum is TS
RP[1]: Trigger
variable [1…65,5
36] Defined similarly to RC, but only 1 bit may be
non-zero. The trigger variable does not need to
be one of the recorded variables.
RP[2]: Pre-trigger
storage in percent [0…100] The percentage of the recorded signal taken
before the trigger event.
RP[3]: Trigger type [0…5] 0: Immediate
1: BG
2: Positive slope
3: Negative slope
4: Window
5: Digital inputs
