1. Press Low Ref (side).
2. On the numeric keypad, press the 2, the 0, and the ENTER (
) buttons,
which sets the low measurement reference to 20%. Observe that the rise-time
value has changed.
3. Press Remove Measrmnt (main) ➞ All Measurements (side). That returns
the display to its original state.
You have seen how to display up to four individual automated measurements on
screen. You can also pop up a display of almost all of the automated measure-
ments available in the Select Measrmnts side menus. This snapshot of measure-
ments is taken on the waveform currently selected using the channel selection
buttons.
As when displaying individual measurements, you must have a stable display of
your signal, and that signal must have all the segments necessary for the
measurement you want.
1. Press Snapshot (main) to pop up a snapshot of all available single waveform
measurements. (See Figure 2–17.)
The snapshot display includes the label Ch 1, meaning that the measure-
ments displayed are taken on the channel 1 waveform. You take a snapshot
of a waveform in another channel by first selecting that channel using the
channel selection buttons.
The snapshot measurements do not continuously update. Snapshot executes a
one-time capture of all measurements and does not update those measure-
ments unless it is performed again.
2. Press Again (side) to do another snapshot and update the snapshot measure-
ments.
3. Press Remove Measrmnt  (main) to remove the snapshot display. (You can
also press CLEAR MENU, but a new snapshot will be executed the next
time you display the Measure menu.)
