Behavior. This timing measurement is the time between the mid reference crossing of two different waveforms, or the gated
region of the waveforms.
The graphic in the control window shows the points on the waveforms from which the delay measurement will be taken. The
graphic is updated each time you change the control settings. The Delay direction controls only apply to Source 2. When you
click Forward, the instrument starts searching for the desired edge at the beginning of the record. When you click Backwards, the
instrument starts searching for the desired edge from the end of the record. If the edge for Source 1 is before the edge for Source
2, then the delay is greater than zero. Otherwise the delay is less than zero.
Mid reference. The Mid reference defines the middle reference level of a waveform; the default level is 50%. This reference
value is primarily used for making measurements between edges such as pulse widths. To change this level, click the control,
and then set the level with the multipurpose knob.
Mid2 reference. The Mid2 reference defines the middle reference used on the second waveform specified in delay or phase
measurements; the default level is 50%. To change this level, click the control, and then set the level with the multipurpose knob.

Delay edges
The Delay Edge buttons determine whether the measurements will be taken on the rising or falling edge of the waveform. After
selecting an edge, the graphic in the control window is updated to show the edge from which the measurements will be taken.
Set up a phase measurement
From the Measure menu highlight More; then select Phase from the submenu. You can also open the More tab in the
Measurement Setup control window, and then click the Phase button under Measurements
