The Data Format Graph is an illustration that displays a graphic representation for the:
Digital Lines
Digital Signals, such as the clock, frame, and data
Data Formats, such as the word size and bit order
Each of the three portions of the this illustration is dynamic. They change as the various N5102A digital signal interface module settings change.
The Digital Lines portion of the Data Format Graph displays digital lines to or from the N5102A module. The clock line is a constant however the Frame and the data lines are changed to reflect the selected module settings. The settings that affect the Data Format are:
Direction (General Settings tab)
Port Configuration (Port Configuration tab)
Port Mapping/Serial Mapping
(Port Configuration tab)
Word Size
(Data Setup tab)
These settings change the types of lines displayed and their labels. They also change the number of lines designated with each line type.
The Digital Signals portion of the Data Format Graph displays digital signals from the N5102A module. The clock line is a constant however the Frame and the data lines are changed to reflect the selected module settings. The settings that affect the Digital Signals are:
Port Configuration (Port Configuration tab)
Port Mapping/Serial Mapping
(Port Configuration tab)
Clock Polarity
(Clock Setup tab)
Clock Phase
(Clock Setup tab)
Clock Skew
(Clock Setup tab)
Clocks Per Sample
(Clock Setup tab)
Word Size
(Data Setup tab)
Bit Order
(Data Setup tab)
Swap IQ
(Data Setup tab)
The Data Format portion of the Data Format Graph displays the size of a word in the data. It also displays the Least Significant Bit (LSB - denoted with "L" in the graphic) and the Most Significant Bit (MSB - denoted with "M"). The settings that affect the Data Format are:
Word Size
(Data Setup tab)
Word Alignment
(Data Setup tab)
Bit Order
(Data Setup tab)
General Settings
Port Configuration
Clock Setup
Data Setup
Clock Connection Graph
