Displaying an Unknown Signal with Connect-and View™

The Connect-and-View™ function enables hands-off operation to display complex unknown signals. This function optimizes the position, range, time base, and triggering and assures a stable display on nearly all waveforms. If the signal changes, the setup will track these changes.

To enable the Connect-and-View™ function, do the following:

∙Connect the red test lead from red input A to the unknown signal to be measured .

Perform an Auto Set.

In the next example, the screen displays “1.411” in large numbers and “-0.103” in smaller numbers. A scope trace gives a graphical representation of the waveform.

The trace identifier (A) is visible on left of the waveform area. The zero icon (-) identifies the ground level of the waveform.
