signal ViInt32 The accepted values depend on the type of connector
See the table below for details.
qualifier1 ViInt32 The accepted values depend on the type of connector
See the table below for details.
qualifier2 ViReal64 If trigger veto functionality is available (AP101/AP201
only), accepts values between 30 ns and 1.0 sec. The
trigger veto values given will be rounded off to steps of
