Speed: What is the difference between 'source delay' and 'trigger delay'?

The trigger delay occurs between the trigger event (for example, the Trigger Link or digital input trigger signal) and turning on the SourceMeter instrument output. The source delay occurs after the output is turned on and before the measurement is taken. The source delay is useful for allowing the circuit under test to settle before making the measurement.
