List Command
set_trigger4
Function Starts the measurement value recording of the specified measurement signals
(has the same effect as set_trigger, but with up to 4 simultaneous measurement signals).
Call set_trigger4( Period, Signal1, Signal2, Signal3, Signal4 )
Parameters Period Like set_trigger.
Signal1 Like set_trigger.
Signal2 Like set_trigger.
Signal3 Like set_trigger.
Signal4 Like set_trigger.
Comments • See comments for set_trigger.
• 2
23
entries per measurement channel are available with set_trigger4, if all 4 signals
are within the allowed range (see set_trigger). The measurement value recording ends
automatically with 2
23
data quadruples.
• If Signal 3 and Signal 4 are not allowed (see set_trigger), set_trigger4 is synonymous
with set_trigger. The memory areas of Signal 3 and Signal 4 are added to the memory
areas of Signal 1 and Signal 2. This allows recording of 2
24
data pairs. The measured
value recording ends automatically with 2
24
data pairs.
• If only Signal 1 is within the permissible range, the memory areas of all 4 channels are
merged into a single one. With this up to 2
25
data values can be recorded. The
measured value recording ends automatically at 2
25
data values.
• An active measured value recording is terminated by
(no matter which of the 3 commands started it):
– set_trigger( Period = 0)
– set_trigger4( Period = 0)
– set_trigger8( Period = 0)
• If set_trigger( Period > 0) or set_trigger4( Period > 0) is used to start a new
measurement value recording, then the measurement value counter is reset. Existing
data is overwritten with new measurement values. See also the corresponding
comments for set_trigger.
• As with set_trigger/set_trigger4, get_waveform/
get_waveform_offset ca
n be used
to transfer the recorded values to the PC.
RTC4RTC6 New command.
RTC5RTC6 Basically unchanged functionality.
Increased memory area for data recordings by merging unused channels, endless
recording.
