4. Functions
This chapter explains the function that can be achieved by hardware and driver's combinations. The
driver indicates the thing of API-DIG(WDM) as long as there is no annotation.
3 practical requirements
This product is equipped with 3 kinds of operation modes to meet the practical requirements.
Oscilloscope Mode
It is the mode that assumes the usage as the oscilloscope of the measuring instrument.
The oscilloscope is used to observe the shape of period waves with vasious frequencies, and confirm the
state of the pulse generated instantly and the edge signal etc.
For that real-time waveform display is necessary for the oscilloscope, the latest waveform data can be
acquired from plural waveform data stored in the memory at any moment.
Moreover, the waveform acquisition operation continues even when the defeat of the wareform occurred
by sample rate and trigger formation condition etc., for that it specializes in the real-time monitoring of
the latest data.
The figure is a data acquisition image in the oscilloscope mode.
The rising edge etc of analog signal are made a trigger, data before and after that is acquired as record
waveform.
When the acquisition processing of a record is not in time, the next record is acquired cancelling the
current record.
Data Logger Mode
It is the mode that assumes the usage as data logger.
It is used to acquire arbitrary waveform and save all the data into a file.
Within the range of on-board memory size, all acquisition data can be acquired regardless of other
acquisition conditions.
Moveover, the data is acquired periodically avoiding the overflow of driver memory, by which infinite
sampling can be performed.
The figure is a data acquisition image in the data logger mode.
In data logger mode, it is possible to control data acquisition timing with two kinds of triggers, pre-
trigger and post-trigger.
