2. Press Measure Delay to (side) repeatedly to choose the delay
to
wave-
form. The choices are Ch1, Ch2, Ch3, Ch4 (on the TDS 644A &
TDS 640A); Ch1, Ch2, Ax1, Ax2 (on the TDS 524A & TDS 620A); and
Math1, Math2, Math3, Ref1, Ref2, Ref3, and Ref4.
Figure 3-49: Measure Delay Menu — Delay To
Delay Edges — The main menu item Edges lets you specify which edges
you want the delayed measurement to be made between.
Press MEASURE Select Measrmnt (main) Delay (side)
Edges (main). A side menu of delay edges and directions will appear.
Choose from one of the combinations displayed on the side menu.
The upper waveform on each icon represents the
from
waveform and the
lower one represents the
to
waveform.
The direction arrows on the choices 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 choice is useful for isolating a specific
pair of edges out of a stream.
