Sampling Functions

The functions used to perform sampling with the digital oscilloscope are as follows.

Sampling type

The sampling type sets the sampling method.
Trigger sampling
Values before and after the trigger (when specified conditions established) are sampled only in the specified range. Sampling
is complete when saving to the specified save destination is complete.

Sampling start settings

Sampling start settings specify conditions required to start sampling with the digital oscilloscope.
User operation
Sampling of the sampling settings file stored in the standard ROM or SD memory card is started with a digital oscilloscope
RUN output, or when the "Sampling settings RUN request (SM860)" turns from OFF to ON.
■RUN from digital oscilloscope
The sampling settings file is specified, and sampling is started with digital oscilloscope RUN. Sampling can be stopped with
digital oscilloscope STOP during sampling.
■"Sampling settings RUN request (SM860)" OFF  ON
"Sampling settings storage target (SD860)" is specified, and sampling is started when "Sampling settings RUN request
(SM860)" is turned ON. Furthermore, sampling is stopped by turning the "Sampling settings RUN request (SM860)" OFF.
Sampling can be performed even when not connected to the personal computer.
Digital oscilloscope request device
Setting item Setting details
Sampling settings Requests sampling. By setting the "Sampling settings storage target" and
RUN request turning ON the RUN request, sampling is started. Sampling is stopped by
turning OFF the request during sampling. This device does not change even
when sampling is complete. The RUN request is ignored even if the device is
turned from OFF to ON while the "Sampling settings RUN status" is ON.

Sampling interval

Set the interval condition for sampling with the digital oscilloscope.
Operation cycle
Sampling is always performed in the operation cycle interval.
Sampling rate specification
Sampling is performed in "0.222ms  sampling rate interval".
Sampling rate range
1 to 10000
