level.

The display will be clipped at higher values.
Computation delay:
[4 s the computation delay of the digital filter] (For details, see
appendix 6.)
The computation time of filters is proportional to the sample rate of the
DSP channel.
If the output result is specified as a source of another DSP channel, the
computation delay increases.
Can specify analog channels (CH1 to CH16) as computation sources. The computed result of a
DSP channel can also be specified as a computation source of another DSP channel. However,
only DSP channels with a channel number smaller than itself can be specified.
The maximum sample rate of analog channels is 5 MS/s when a DSP channel is turned ON.

Recording start trigger
Recording can be started using a trigger by setting the trigger mode.
Auto:
Trigger disabled. Continuous recording. Recording starts with measurement start.
Log:
Trigger disabled. Recording stops when the memory storage length of data is acquired.
When short recording is specified, recording stops when shot recording ends.
Single: Trigger enabled. Recording starts after a trigger detection.
When short recording is specified, recording stops when shot recording ends.
Repeat: Trigger enabled. Recording starts after a trigger detection.
Selectable only when shot recording is specified. Reenters trigger-wait state after short
recording.
