12 Peripheral Devices
This chapter provides information on peripheral devices used with PSG signal generators. The
N5102A Baseband Studio digital signal interface module and extended frequency source module
operation and features are described in the following sections:

Clock Timing
This section describes how clocking for the digital data is provided. Clock timing information and
diagrams are supplied for the different port configurations (serial, parallel, or parallel interleaved
data transmission) and phase and skew settings. All settings for the interface module are available on
the signal generator user interface (UI).
Clock and Sample Rates
A sample is a group of bits where the size of the sample is set using the Word Size softkey. The clock
is the signal that tells when the bits of a sample are valid (in a non- transition state). The clock and
sample rates are displayed in the first- level and data setup softkey menus. The clock rate and sample
rate are usually the same. They will differ when serial mode is selected, or when there are multiple
clocks per sample.
