Recalling a Waveform from SAVE REF
Once a waveform is stored in a SAVE REF memory location, simply press
the memory location button to recall or remove it from memory. The con-
tents will remain intact even after the power is turned off. There is no over-
write protection on these memories, however. Pressing the
SAVE REF and
memory location button will save a new waveform to that location and
overwrite the old.
Comparing Saved Waveforms
You can simultaneously display the contents of more than one SAVE REF
memory location. This enables you to compare one saved waveform with
another.
Step 1 : Press one or more memory location buttons to display their
respective contents.
Step 2: Change the position, horizontal magnification, or vertical gain of
the saved waveform display using the
Format reference menu. (Refer to
the following section.)
Step 3: Press the SELECT WAVEFORM button (next to the cursor
control) one or more times until the cursors appear on the waveform you
want to measure. An underscore appears under the selected
SREF
memory number at the top of the display.
Formatting Saved Waveforms
You can change the horizontal magnification, vertical position, and vertical
gain of a waveform in a
SAVE REF memory location.
Step 1 : Press the front-panel Setup REF button.
Step 2: Press the left Save Ref menu to indicate Format. The Format
Reference Menu appears (Figure 3-43).
Step 3: Select the Target Ref (Refl, Ref2, Ref3, or Ref4K) to indicate
the desired memory location.
