Channel Readings, Acquire, and Post-Acquisition Buttons
Select the <Channel Readings> button. If in the Simulated Instrument mode, the
Reading column of the Analog & Scanned Digital Inputs spreadsheet will display
simulated data. Selecting the <Channel Readings> button again freezes the Reading
column display. If working hardware is connected, the readings will quantify actual
signals.
Additional information is provided in Chapter 4 under, Toolbar Items, Channel Setup
Buttons.
The Acquire selection activates an acquisition of data to file. The Event option under the
Trigger Setup portion of the Main window determines when the Acquire process is
initiated. The Event selections are detailed in the Acquisition Setup section of this
chapter. After Acquire is selected, the process is automatic beginning with the DaqView
Armed screen. This screen posts the Trigger Armed time as well as the Trigger Event
information. The Acquire process makes use of the Data File Setup parameters to format
data collection.
Once the Trigger Event occurs, the DaqView Triggered screen appears. This screen
allows you to witness the data sampling parameters you set in the Main window prior to
initiating the Acquire process as well as the progress of the data acquisition.
If file conversion is selected, the Acquire process concludes by converting the generated
.BIN file from binary to ASCII data. The resulting file is saved under a user-specified
directory and file name or as a default under the DaqView subdirectory as DAQV.TXT.
This .TXT file is available for data processing or analysis by various software packages
such as ViewXL.
This button is used to launch an independent post-data acquisition program, such as
eZ-PostView. For details, refer to the eZ-PostView PDF document that is included on
your data acquisition CD. You can access the document via the button
located on your CD’s intro-screen.
