Operating the N5102A Module in Output Mode

This section shows how to set the parameters for the N5102A Option 003 module in output mode using the front- panel keys. Each procedure contains a figure that shows the softkey menu structure for the interface module function being performed.

Setting up the Signal Generator Baseband Data

The digital signal interface module receives data from a baseband source and outputs a digital IQ or digital IF signal relative to the selected logic type. Because the PSG provides the baseband data, the first procedure in operating the interface module is configuring the PSG using one of the real- time or ARB modulation formats, or playing back a stored file using the Dual ARB player. For information on setting up real- time or ARB waveforms, or to learn about using the Dual ARB player, refer to the appropriate chapter in this guide.

1.Preset the signal generator.

2.Select the modulation format (TDMA, Custom, and so forth) and set the desired parameters.

3.Turn- on the modulation format.

Accessing the N5102A Module User Interface

Press Aux Fctn > N5102A Interface.

This accesses the UI (first- level softkey menu shown in Figure 11- 9) that is used to configure the digital signal interface module. Notice the graphic in the 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.
