6. Functions
Clock
The sampling clock controls the sampling frequency. You can select either the internal sampling clock, or
external sampling clock. The sampling clock is selected by means of software.
- Internal sampling clock
The clock signal from the on-board clock generator is used.
- External sampling clock
The edge of the digital signal input from an external device is used for the sampling clock.
Start Condition
The condition for controlling the start of sampling can be selected from among software, external trigger.
The conditions for controlling the start and stop of sampling are completely independent of each other;
they can be set separately.
- Software
This product starts sampling and storing input data to memory immediately after the operation start
command is issued.
- External trigger
This product starts waiting for an external control signal as soon as the operation start command is
output.
Sampling and data transfer from memory start when the specified edge (rising edge or falling edge)
is input from the external control signal.
Stop Condition
The condition for controlling the stop of sampling can be selected from among the last sampling count,
an external trigger, and software abort.
This product stops sampling whenever an error occurs irrespective of the stop condition setting.
- Last sampling count
This product stops sampling after storing input data to memory for the specified number of times of
sampling.
- External trigger
This product starts waiting for an external control signal after the specified number of samples have
been performed. Sampling stops when the specified edge (rising edge or falling edge) is input from
the external control signal.
- Software
Sampling continues indefinitely in this mode. Sampling only stops in response to a software
command or an error.
