How Does the NI‑7935R Work?
The NI‑7935R divides system functions across the FlexRIO adapter module, Kintex‑7 FPGA and embedded real-time processor.
A simplified acquisition path is:
Signal or DUT → FlexRIO Adapter Module → Kintex‑7 FPGA → FPGA DRAM / DMA / SFP+ → Real-Time Controller or Remote System
During acquisition, the adapter module converts or interfaces with the incoming signal. The FPGA performs deterministic triggering, filtering, protocol processing or data reduction.
The resulting data can be:
- Buffered in the 2 GB FPGA DRAM
- Transferred to the real-time processor through DMA
- Streamed through the SFP+ ports
- Logged to compatible storage
- Transferred over Ethernet
For signal generation, data can travel from FPGA memory or the real-time application through the FPGA and installed adapter module to the connected DUT.
NI‑7935R Is a Controller for FlexRIO
The NI‑7935R is not a complete measurement instrument without an appropriate FlexRIO adapter module.
