DIGITAL DISPLAY

X versus Y

Similar to the analog mode, the digital mode allows you to display one trace as a function of another.

The source for vertical direction (Y) is selected by the TRACK control. It can be the acquired trace or a saved track in a memory location (e.g., m3).

For horizontal direction (X) you can choose from an active channel signal saved in memory (e.g., m3.1).

-Press the ANALOG key to select the digital mode.

-Press the DISPLAY key.

-Press the X vs Y softkey.

-Press the ’on off’ softkey to turn it on.

-Press the X SOURCE softkey to select ’ch1’.

Now two horizontal lines (Ch 1 against Ch 2) are displayed. Horizontal deflection is determined by the amplitude of the sine wave.
