DATA CAPTURE
To initiate conversions and to capture the sample data, you must
click the Single Acquisition or the Reoccurring Acquisition
button.
When the Single Acquisition button is clicked, the software
instructs the EVA L -SDP-CB1Z to read back the conversion
results from the E VA L -AD2S1200/05SDZ board. The number
of samples is selected via the Number of Samples box. After
each conversion, data from the AD2S120x is written to external
memory on the E VA L -SDP-CB1Z. The required set of samples
is uploaded through the USB port to the PC when all conver-
sions are completed.
When you click the Reoccurring Acquisition button, the software
instructs the EVA L -SDP-CB1Z to read back the conversion
results from the E VA L -AD2S1200/05SDZ board in a repeating
loop. The number of samples is selected via the Number of
Samples box. After each conversion, data from the AD2S120x is
written to external memory on the EVA L -SDP-CB1Z. The
required set of samples is uploaded through the USB port to the
PC when all the conversions are completed. If the Reoccurring
Acquisition button is not clicked again to release the loop, the
conversion loop repeats. While the data is being uploaded to the
PC, the AD2S120x device is not converting; therefore, there may
be a time delay between two blocks of samples.
In single acquisition and reoccurring acquisition mode, the data
is displayed on the data capture display. The data is displayed on
the Acquisition (Codes), Acquisition (Degrees/RPS),
Histogram Position, and Histogram Velocity tabs.
Figure 16 shows a typical data capture. Both position and velocity
data results are presented in the data capture display. Additionally,
the following data is displayed:
• A summary of the measured positional data
• A summary of the measured velocity data
