Example: FlexRIO Ethernet Interface
For recording traffic over Ethernet, there are software solutions. However, if one needs to demonstrate the precise timing behavior of a control device down to the range of a few nanoseconds, software solutions are not sufficient. In this case, it is necessary to implement hardware that accesses the physical interface.
The FlexRIO-PXI cards from National Instruments have proven to be an excellent basis for this challenge. They can be easily integrated into the existing PXI test system at the customer site and are extremely powerful for the fast processing and storage of large amounts of data.
IRS developed an adapter module as an addition to the FlexRIO base, which allows testing of up to 4 Ethernet interfaces. Additionally, digital channels are available, each of which logs every edge change with a timestamp. This allows for temporal correlations to be determined between the exact timestamps of the Ethernet frames and digital switching operations. The Ethernet frames and digital switching operations can be continuously streamed to disk with their respective 20ns timestamps.
An analysis tool exists for offline analysis to visualize the received data.
Generation and detection of pulse signals
In-house development of a FlexRIO adapter module based on customer specifications.
Generation and recording of pulses with adjustable pulse width and period duration for different voltage levels (TTL, CMOS, etc.) in the nanosecond range.
