(1)-1 Sample interval
Sets the data recording interval.
The fastest sample interval that can be set is limited by the following items. If a sample interval that cannot
be recorded is set, the color changes and this mark is displayed. (
If the sample interval displays this mark, please change the recording destination when going to record.

*1: The fastest sample interval changes depending on the connected amplifier module type.
The possible recording sample interval varies for each connected Amplifier Module. When combining
different types of Amplifier modules, the sample interval of the fastest Amplifier Module can be set, but
the slow Amplifier module continues with the same data until data changest at the fastest sampling
interval it can manage.
Fastest amplifier
*2: When a Logic/Pulse module is connected and a pulse selected, 8ch(CH1~CH8) can be recorded at 1 μ.
However, the maximum sampling rate of the pulse is 100 μs, so the data is updated only every 100 μs.)
*3: When a Logic/Pulse module is connected and a pulse slected, 16ch can be recorded over 2μ. When two
modules are connected, and a pulse slected, each module can record data to 8ch(CH1~CH8). (However,
the maximum sampling rate of the pulse is 100 μs, so the data is updated only every 100 μs.)
< Ex. 1> Sampling 1 μ
The pulses of CH1 to CH8
are recorded.
*4: Depending on the state of fragmentation of the SSD, there may be cases where the sampling rate won't
be written on time (A message will be displayed during recording). If this sort of event occurs, please
backup important data to another media and format the SSD.
