Instrument Handle In specifies the session created by the Scope Initialize VI.
Error In describes error conditions that occur before this node runs. This input provides standard error in functionality.
Trigger Hysteresis returns the window, in volts, below Trigger Level. Hysteresis reduces false triggering due to noise or jitter in the signal. If the edge is rising, the input voltage must pass below Trigger Level minus Trigger Hysteresis before the input voltage is recognized as a trigger. If the edge is falling, the input voltage must pass above Trigger Level plus Trigger Hysteresis.
Instrument Handle Out returns a reference to the instrument.
Trigger Source returns the trigger signal.
Trigger Slope returns on which edge of the trigger signal a trigger occurs.
Name Value Description
Rising 0 A trigger occurs on a rising edge.
Falling 1 A trigger occurs on a falling edge.
Either 2 A trigger occurs on either a rising or a falling edge.
Trigger Level returns the voltage at which a trigger occurs.
Error Out contains error information. This output provides standard error out functionality.
