waveform for the specified channel must exist in the specified reference, or
the logic scope displays an error message.
4. Press Edges (side). A side menu of delay edges and directions will appear.
5. Choose from one of the combinations displayed on the side menu.
The upper waveform on each menu label represents the from waveform, and
the lower one represents the to waveform.
The direction arrows on each menu label let you specify a forward search on
both waveforms or a forward search on the from waveform and a backwards
search on the to waveform. The latter case is useful for isolating a specific
pair of edges out of a stream.
6. Press Delay To (main)
➞
OK Create Measurement (side) to take the
measurement you have specified.
To exit the Measure Delay menu without creating a delay measurement, press
CLEAR MENU, which returns you to the Measure menu.
To measure phase, select the waveform to measure phase to (the waveform to
measure phase from is the selected channel in the selected group). Then create
the phase measurement as was just described for the delay measurement. You do
not select waveform edges when measuring phase.
To measure setup, you select the waveform group to measure, the channel that
contains its clock, and the edge of the clock you want to measure setup relative
to. To do these tasks, perform the following steps:
1. Use the group selection buttons to select any live or reference group.
2. Press MEASURE
➞
Select Measrmnt (main)
➞
Setup (side). (Press
–More– (side) as needed to display the setup items.) (See Figure 3-36.)
