Configuration software KS2000
KL3361 and KL3362 43 Version: 2.2.0
Scaling channel 1
User offset ( R33 [
}
59] )
default: 0
Here you can enter an offset. Scaling:
offset = full scale value x parameter /
resolution
Sample for KL3361: 16 mV x 100 / 32767 =
0.049 mV
User gain ( R34 [
}
59] )
default: 256
Here you can enter the gain factor for
scaling the input value by this factor.
Scaling channel 2 (KL3362 only)
User offset ( R33 [
}
59] )
default: 0
Here you can enter an offset. Scaling:
offset = full scale value x parameter /
resolution
Sample for KL3361: 16 mV x 100 / 32767 =
0.049 mV
User gain ( R34 [
}
59] )
default: 256
Here you can enter the gain factor for
scaling the input value by this factor.
4.5.3 Trigger values
Trigger unit 1
Switching threshold 1 ( R41
[ } 62] )
default: 1000
Here you can specify the switching threshold
for the trigger source of trigger unit 1. Scaling:
Threshold value = full scale value x parameter /
resolution
Sample for KL3361: 16 mV x 1000 / 32767 =
0,488 mV
Switching threshold 2 ( R42
[ } 63] )
default: 1000
Here you can specify the switching threshold
for enabling the trigger of trigger unit 1.
Scaling: see Switching threshold 1.
Pulse width ( R43 [
}
63] )
default: 100
Here you can specify the pulse width (t
P
) of
trigger unit 1 for the glitch mode. The number
of samples (n
SP
) is entered as the parameter.
The pulse width thus depends on the sample
rate! Sample:
- Sample rate: T
s
= 200 µs
- Samples: n
SP
= 100
Pulse width: t
P
= T
s
x n
SP
= 200 µs x 100 =
20 ms
valid trigger time ( R44
[ } 63] )
default:
Here you can specify the valid trigger time (t
VT
)
for trigger unit 1. The number of valid samples
(n
VS
) is entered as the parameter. The valid
trigger time thus depends on the sample rate!
Sample:
- Sample rate: T
s
= 200 µs
- valid samples: n
VS
=100
Valid trigger time: t
VT
= T
s
x n
VS
=200 µs x 100 =
20 ms
Timeframe active ( R40.6
[
}
62] )
default: not activated
Here you can switch on the timeframe for
trigger unit 1.
