:MEASure:TEDGe

Query Syntax
:MEASure:TEDGe? <slope><occurrence>[,<source>]
<slope> ::= direction of the waveform. A rising slope is indicated by a
<occurrence> ::= the transition to be reported. If the occurrence number
<source> ::= {CHANnel<n> | FUNCtion | MATH}
<n> ::= {1 | 2 | 3 | 4} for the four channel oscilloscope models
<n> ::= {1 | 2} for the two channel oscilloscope models
When the :MEASure:TEDGe query is sent, the displayed signal is searched
for the specified transition. The time interval between the trigger event
and this occurrence is returned as the response to the query. The sign of
the slope selects a rising (+) or falling (- ) edge. If no sign is specified for
the slope, it is assumed to be the 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 threshold in the positive direction. Once this crossing is found,
the oscilloscope reports the time 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. This value is returned if the waveform does not cross the
specified vertical value, or if the waveform does not cross the specified
vertical value for the specific number of times in the direction specified.
You can make delay and phase measurements using the MEASure:TEDGe
command:
For an example of making a delay and phase measurement, see
":MEASure:TEDGe Code"
If the optional source parameter is specified, the current source is
modified.
This query is not available if the source is FFT (Fast Fourier Transform).

minus sign (-).

reported, etc.
Delay = time at the nth rising or falling edge of the channel - time at
the same edge of another channel
Phase = (delay between channels / period of channel) x 360
If the number is two, the second crossing is
on page 282.
