Digital Signal Interface Module (Option 003/004)
Operating the N5102A Module in Input Mode
9. Press the Clock Polarity Neg Pos softkey to Neg.
This shifts the clock signal 180 degrees, so that the data starts during the negative clock
transition. This has the same affect as selecting the 180 degree phase adjustment.
10. Make the clock polarity selection that is required for the device being tested.
11. Press the Return hardkey to return to the first- level softkey menu.
The clock source selection is also reflected in the first- level softkey menu graphic. For example, if
the device is the new clock source, you will see that the frequency reference is now connected to
the DUT and the DUT has an input clock line going to the N5102A module.
Selecting the Data Parameters
This procedure guides you through the data setup menu. Softkeys that have self- explanatory names
are generally not mentioned. For example, the Word Size softkey.
1. Refer to Figure 10- 21. Press the Data Setup softkey.
Figure 10-21 Data Setup Menu Location
This softkey menu accesses the various parameters that govern the data received by the signal
generator. The status area of the display shows the number of data lines used for both I and Q
along with the clock position relative to the data.
Figure 10- 22 shows the data setup menu
structure.
