Note
The smaller the ratio between block size and sampling rate
is, the more often the worksheet gets updated. Use a ratio of
0.1 s to 1 s .
Click Measurement Setup on the function bar to specify the sampling
rate and the block size. You can specify the sampling rate and the
block size in the measurement settings dialog box or you only specify the
sampling rate and DASYLab specifies the block size as shown in Figure 7-1.
If you do not have hardware installed, DASYLab uses the computer clock as
the timer. If you specify a default driver under Measurement»Select Driver,
you can use the hardware clock. The settings Driver buffer, Analog output,
and Digital output also refer to the default driver.
Figure 7-1. Measurement Settings of the Default Driver
Depending on the installed hardware, DASYLab provides further
timers apart from the system clock and the default driver clock. Click
Time Base Setup on the function bar to view the tabs of the available timers
and to change them. The DASYLab tab contains the system clock settings.
The Driver tab contains the default driver settings. If you install DLL drivers
with individual sampling rates such as NI-CAN or instruNet, the time base
settings dialog box also contains the tabs NI-CAN and instruNet.
