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.
-
Event controller output
A specified output of the event controller is used as the sampling clock.
Refer to the explanation of the event controller functions or to the driver help for details about the
event controller.
Start Condition
The condition for controlling the start of sampling can be selected from among software, external
trigger and an event controller. The conditions for controlling the start and stop of sampling are
completely independent of each other; they can be set separately.
- Software
The board starts sampling and storing input data to memory immediately after the operation start
command is issued.
- External
trigger
The board 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.
-
Event controller output
The board 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 event controller output is
received.
Refer to the explanation of the event controller functions or to the driver help for details about the
event controller.
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.
The board stops sampling whenever an error occurs irrespective of the stop condition setting.
-
Last sampling count
The board stops sampling after storing input data to memory for the specified number of times of
sampling.
- External
trigger
The board 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.
