4.4.3 Measurement period [[]

This function sets/selects the sampling period to use the hold measurement.

Trigger level and trigger hysteresis

For internal trigger down operation

By setting the trigger hysteresis, the chattering of the internal trigger signals can
be ignored.

The trigger level and trigger hysteresis are specified with numerical values.

Note 1: The trigger level can be set within the range of

±19.999.

Note 2: The trigger hysteresis can be set up to +19.999.

*

The trigger hysteresis is factory-adjusted to 10 digits.

Sampling delay and sampling period

Sampling delay
Specify the time between the instant when the trigger signal turns ON and the
beginning of the sampling period.
