Procedure
(1) Chose the device name of the device to be used from the upper left combo box, and click the setting
button.
(2) The conversion conditions are set on the screen of the setting analog output.
Once an output is done at the sampling frequency specified as data setting sampling frequency, an
event occurs and data will be added. Click the OK button to finish setting the conditions, and
returns to former screen.
(3) Start the measurement with measurement start button. The various states during the conversion
are displayed.
The number of the samplings in FIFO is :
It is conversion data set in the memory. This can be visually checked in a "memory image".
Event generation sampling frequency :
When the number of unoutput sampling in FIFO reaches this frequency, the event generates.
Adding sampling frequency :
It is the number of samplings of output data to be added during the event.
Measurement may stop by the following errors.
Sampling clock error :
It means that the conversion speed is too fast and the driver processing is not in time when
converting at the internal clock.
The cycle of the clock is too fast when converting it at the external clock. Moreover, the cause by
noise etc. is also concerned.
(4) Click the “stop” button, and measurement stops.
