Programmable Features
Channels can be configured through your own custom programs or through the included out-of-the-box
WaveView software. WaveView includes a Channel Configuration screen (following figure) that allows
you to turn channels ON or OFF, select channel ranges, change channel labels, and select engineering units.
Reference Note:
Chapter 6, WaveView contains more detailed information. Individuals who write their own
programs should refer to the readme.txt file on the install CD-ROM regarding the location of
API reference material, including program examples.
