Operating the N5102A Module in Input Mode

This section shows how to set the parameters for the N5102A module using the signal generator UI in the
input direction. Each procedure contains a figure that shows the softkey menu structure for the interface
module function being performed.

Refer to

“Connecting the Clock Source and the Device Under Test” on page 60

and configure the test setup.

Accessing the N5102A Module User Interface

All parameters for the N5102A module are set with softkeys on the ESG/PSG signal generator.

Press

.

This accesses the UI (first-level softkey menu shown in

Figure 4-15

) that is used to configure the digital

signal interface module. Notice the graphic, in the ESG/PSG display, showing a setup where the N5102A
module is generating its own internal clock signal. This graphic changes to reflect the current clock source
selection.
