Setting the display format

The instrument can display waveforms in two different formats. Choose the format that best suits your needs.

Select Display >Display Format.

■

Select YT format to show a signal

amplitude as it varies over time.

■

Select XY format to compare the

amplitude of waveform records point by

point:

The following channels are compared on

instruments without ATI channels:

Ch 1 (X) and Ch 2 (Y),

Ch 3 (X) and Ch 4 (Y),

Ref 1 (X) and Ref 2 (Y),

Ref 3 (X) and Ref 4 (Y)

The following channels are compared on

instruments with ATI channels:

Ch 1 (X) and Ch 3 (Y),

■

Select XYZ format to compare the

voltage levels of the Ch 1 (X) and Ch

2 (Y) waveform records point by point as

in XY format. The displayed waveform

intensity is modulated by the Ch 3 (Z)

waveform record. XYZ format is

triggered. A -5 division signal (including

position and offset) on Ch 3 produces a

blank screen; a +5 division signal

produces full intensity.

Quick tips

■

XY format is particularly useful for studying phase relationships such as Lissajous Patterns.

■

XY format is a dot-only display, although it can have persistence. The Vector style selection has no effect when you select

XY format.
