R42: Trigger unit 1, switching threshold 2
Switching threshold for enabling the trigger [
}
43] (EnableSource) of trigger unit 1
R43: Trigger unit 1, pulse width
Here you can specify the pulse width [
}
43] (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
R44: Trigger unit 1, valid trigger time
Here you can specify the valid trigger time [ } 43] (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
R46: Trigger unit 2, trigger logic
see Trigger detector 1 [
}
62]
R47: Trigger unit 2, switching threshold 1
Switching threshold for the trigger source (TriggerSource) of trigger unit 2
R48: Trigger unit 2, switching threshold 2
Switching threshold for enabling the trigger (EnableSource) of trigger unit 2
R49: Trigger unit 2, pulse width
Here you can specify the pulse width (t
P
) of trigger unit 2 for the glitch mode (see Trigger unit 1, pulse width
[ } 63] ).
R50: Trigger unit 2, valid trigger time
see Trigger unit 1, valid trigger time [ } 63]
R52: Trigger delay
A trigger delay [ } 42] (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
R53: Parameter 1 envelope curve
e.g. distance of the inner envelope curve
After the trace recording, the envelope curve is evaluated.
R54: Parameter 2 envelope curve
e.g. distance of the outer envelope curve
After the trace recording, the envelope curve is evaluated.
