11.2 Parameters and setting ranges
11.2.1 Parameter list
♦ <Rise time>
The parameter ‚Rise time’ corresponds to the charge time-constant of
the peak-peak measurement. The rise time can be set up within a
specific setting range.
Setting range for the time-constant of the rise time:
Minimum: 0 ms Maximum: 99 ms Step size 1 ms
Works pre-setting 3 ms
Hint for the rise time setting:
A long rise time tends to smooth out very fast signal progressions. The
resultant measured value can therefore be lower than when a short rise time
is set.
With a rise time of 0 ms, the actual maximum signal increase in the signal’s
progression will be acquired as the peak-peak measurement.
♦ <Decay time>
The parameter ‚decay time’ corresponds to the discharge time-constant
of the peak-peak measurement. The decay time can be set up within a
specific setting range.
Setting range for the time-constant of the decay time:
Minimum: 0.1 s Maximum: 9.9 s Step size 0.1 s
Works pre-setting 5 s
Hint about the decay time:
A long time-constant for the decay time tends to also smooth out very fast
signal progressions. Thus the measured peak-peak value will be maintained
at a higher level for a longer period of time than when a short decay time-
constant is set.
