HOW TO USE THE INSTRUMENT
DIGITAL DISPLAY
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.
The X vs Y submenu displays the selection menu for the X and Y sources.
Observe that you can select the Y source (REGISTER) using the TRACK control.
Use the softkeys to choose the X source.
- Remove the signal from channel 2.
