KL3361 and KL3362 42 Version: 2.2.0
4.5.2 General settings
Operation mode
Pre-trigger ( R32.8-10 [
}
59] ) Recording ceases as soon as a trigger
event occurs.
Mid-trigger ( R32.8-10
[ } 59] )
The trigger event is the center of the
recording.
Post-trigger ( R32.8-10
[ } 59] )
default
Recording commences as soon as a trigger
event occurs.
Fast sampling ( R32.8-10
[
}
59] )
Operation with increased sampling rate of
up to 10 µs:
• The recording can only be started via the
trigger input.
• The settings of the trigger units are not
taken into account.
• Only the first channel is recorded, even
for KL3362.
Trigger delay active ( R32.4
[ } 59] )
default: not activated
Switches the trigger delay on.
Trigger delay ( R52 [
}
63] )
default: 0
A trigger delay (t
TD
) can be specified here.
The number of skipped samples (n
STD
) is
entered as the parameter. The trigger delay
thus depends on the sample rate! Sample:
- Sample Rate: T
s
= 200 µs
- Skipped Samples: n
STD
=100
t
TD
= T
s
x n
STD
= 200 µs x 100 = 20 ms
Test mode active ( R32.5
[
}
59] )
default: not activated
Switches the test mode on. In test mode, a
ramp is output instead of converted analog
values. It runs from 0 to 0x3FFF and back
again.
Auto-trigger active ( R32.6
[
}
59] )
default not activated
Switches the auto trigger function on. With
auto trigger switched on, the trigger unit is
automatically activated once the preceding
event has been evaluated. To this end, bit 0
is toggled in status register 1 (SR1) with
each new evaluation.
General
Sample rate ( R35 [ } 60] )
default: 200 µs
Interval (T
s
) between two samples (scans) in
microseconds.
The sampling speed is limited to T
s
=100 µs
(10 kHz) by the evaluation of the trigger
detectors.
Only the
Fast sampling mode enables
sampling at T
s
=10 µs (100 kHz).
Sample amount ( R36 )
default: 100
Number of sampling values to be recorded.
A maximum of 4,000 values can be
recorded.
Trigger frequency ( R56
[
}
64] )
default: 0
Here you can specify the trigger frequency
of the
timer [ } 33] .
