446 Keysight EXG and MXG X-Series Signal Generators User’s GuideUsing the N5102A Digital Signal Interface Module for N5172B/82B with Option 003/004 and653/655/656/657Operating the N5102A Module in Input Mode2. Select the logic type required for the device being tested.A caution message is displayed whenever a change is made to the logic types, and a softkeyselection appears asking for confirmation.3. Refer to Figure 17-18. Press the Port Config softkey.In this menu, select either a serial, parallel, or parallel interleaved data transmission.4. Select the port configuration for the device being tested.Configuring the Clock Signal1. Refer to Figure 17-19. Press the Clock Setup softkey.Figure 17-19 Clock Setup Menu LocationFrom this softkey menu, set all of the clock parameters that synchronize the data between theN5102A module and the device. From this menu, the clock signal phase can be changed so theclock occurs during the valid portion of the data. Figure 17-20 shows the clock setup menu.If the device or external clock does not match the frequency, one of the following errormessages will appear on the signal generator:803 Digital module input FIFO overflow error; There are moresamples being produced than can be consumed at thecurrent clock rate. Verify that the digital module clockis set up properly.This error is reported when the digital module clock setup is notsynchronized with the rate the samples are entering the digitalmodule. Verify that the input clock rate matches the specifiedclock rate under the clock setup menu.Within the data and clock setup softkey menus, some softkeys function relative to the currentconfiguration. Softkeys that are grayed out are not available for the current setup. Refer to thehelp text to determine which parameter is causing the softkey to be unavailable. Press the Helpkey on the signal generator front panel and then the softkey that is unavailable.Accesses the Clock SetupMenu
