Using the N5102A Digital Signal Interface Module for N5172B/82B with Option 003/004 and
653/655/656/657
Operating the N5102A Module in Input Mode
804 Digital module input FIFO underflow error; There are not
enough samples being produced for the current clock rate.
Verify that the digital module clock is set up properly.
This error is reported when the digital module clock setup is not
synchronized with the rate the samples are entering the digital
module. Verify that the input clock rate matches the specified
clock rate under the clock setup menu.
Figure 17-20 Clock Setup Softkey Menu for a Parallel Port Configuration
The top graphic on the display shows the current clock source that provides the output clock
signal at the Clock Out and Device Interface connectors. The graphic changes to reflect the
clock source selection discussed later in this procedure. The bottom graphic shows the clock
edges relative to the data. The displayed clock signal will change to reflect the following:
— clock phase choice
— clock skew adjustment
— clock polarity selection
2. Press the Clock Source softkey.
From this menu, select the clock signal source. With each selection, the clock routing display
in the signal generator clock setup menu will change to reflect the current clock source. This
will be indicated by a change in the graphic.
Inactive for Input mode
