4. Functions
Waveform judgment setting
Mask setting
To use the waveform judgment function, you should make the mask data that becomes the comparison
object and set it to the digitizer beforehand.
There are three methods for making the mask data: generate the data automatically while acquiring the
actual waveform, generate the data using GUI software "Mask Editer" and generate the data in a
program.
Waveform judgment counter
It is possible to count the number of times of the waveform judgment result (PASS/FAIL) for each
record data.
A limit value is set to the counter, when the number of generation times of PASS or FAIL reached the
limit, the digitizer operation is stopped and the signal is output to outside.
Output the result of waveform judgment
The result of the waveform judgment can be output outside as a digital signal.
Such conditions can be set as outputting once/outputting every judgment result, pulse output/level
output, and positive logic/negative logic.
Operation Control
Synchronization start/Asynchronization start
There are two methods for starting the digitizer operation, synchronization and asynchronization.
When asynchronization start is used, the driver function issues a start command to the digitizer and
returns immediately.
Therefore, the application can do other processing during the digitizer operation.
On the other hand, it is necessary to observe the digitizer state regularly or use the event notification
function so that the application knows the operation completion of the digitizer.
It is necessary to use asynchronization start for infinite sampling.
When synchronization start is used, the driver function doesn't return the control until the the digitizer
stopped operating.
Therefore, the application cannot do other processing until the digitizer stopped operating.
On the other hand, the programming becomes concise for there's no need to detect the operation
completion of the digitizer.
