NOTE
When the horizontal scale is set to a rate faster than 25 ns/div, or
when using the ZOOM feature to expand waveforms horizontally,
interpolation occurs. (The filter type, linear or sin(x)/(x), depends on
which is set in the Display menu.) Otherwise, interpolation is not
needed. See Sampling and Digitizing starting on page 2-7 in the
Concepts
section for a discussion of sampling including interpola-
tion.
Graticule Type
To change the graticule:
Press DISPLAY
➞
Graticule (main)
➞
Full, Grid, Cross Hair, or Frame
(side).
H
Full provides a grid, cross hairs, and a frame.
H
Grid displays a frame and a grid.
H
Cross Hair
provides cross hairs and a frame.
H
Frame displays just a frame.
Format
There are two kinds of format: YT and XY.
YT is the conventional oscilloscope display format. It shows a signal voltage
(the vertical axis) as it varies over time (the horizontal axis).
XY format compares the voltage levels of two waveform records point by
point. That is, the oscilloscope displays a graph of the voltage of one wave-
form record against the voltage of another waveform record. This mode is
particularly useful for studying phase relationships.
To set the display axis format:
Press DISPLAY
➞
Format (main)
➞
XY or YT (side).
When you choose the XY mode, the input you have selected is assigned to
the X-axis and the oscilloscope automatically chooses the Y-axis input (see
Table 3-2).
