8.4 Functional Testing
This tool tests the A/D functions of the card. When you select
Function testing. <3> from the main menu, the function test
window appears.
Use the function keys at the bottom of the window to set the trigger
mode, trigger signal polarity, trigger level, channel number and
post trigger count (for middle trigger and delay trigger). When
finished, press <Enter> to perform testing. This function tests and
views the effects of various trigger modes. In addition, an arrow
shown on the screen indicates the trigger position. If the trigger
source is also an enabled A/D channel, you can easily view the
result of changing trigger levels.
