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.)
