Measurement System
TDS 620A, 640A, & 644A User Manual
Creating the Delay Measurement — Once you have specified the
waveforms you are measuring between and which edges to use, you need to
notify the digitizing oscilloscope to proceed with the measurement.
Press Delay To (main) ➞ OK Create Measurement (side).
To exit the Measure Delay menu without creating a delay measurement,
press CLEAR MENU, which returns you to the Measure menu.
Sometimes you may want to see all of the automated measurements on
screen at the same time. To do so, use Snapshot. Snapshot executes all of
the single waveform measurements available on the selected waveform

once

and displays the results. (The measurements are not continuously updated.)
All of the measurements listed in Table 3-5 on page 3-86 except for Delay
and Phase are displayed. (Delay and Phase are dual waveform measure-
ments and are not available with Snapshot.)
The readout area for a snapshot of measurements is a pop up display that
covers about 80% of the graticule area when displayed (see Figure 3-50). You
can display a snapshot on any channel or ref memory, but only one snapshot
can be displayed at a time.
