The time interval between the trigger event and thisoccurrence is returned as the response to the query. The sign of the slope selects arising (+) or falling (-) edge. If no sign is specified for the slope, it is assumed to bethe rising edge.The magnitude of occurrence defines the occurrence to be reported. For example,+3 returns the time for the third time the waveform crosses the midpoint thresholdin the positive direction. Once this crossing is found, the oscilloscope reports thetime at that crossing in seconds, with the trigger point (time zero) as the reference.If the specified crossing cannot be found, the oscilloscope reports +9.9E+37. Thisvalue is returned if the waveform does not cross the specified vertical value, or ifthe waveform does not cross the specified vertical value for the specific number oftimes in the direction specified.You can make delay and phase measurements using the MEASure:TEDGecommand:Delay = time at the nth rising or falling edge of the channel - time at the sameedge of another channelPhase = (delay between channels / period of channel) x 360For an example of making a delay and phase measurement, see":MEASure:TEDGeCode"on page 538.If the optional source parameter is specified, the current source is modified.
