The NI 6581 is a 100 MHz digital
adapter module for NI FlexRIO
field-programmable gate array (FPGA)
modules. This adapter module features
54 single-ended digital I/O lines with
software-selectable voltages of 1.8,
2.5, and 3.3 (5 V tolerant). You can also reference an external voltage (ranging from 1.8V to 5.5V independently for each of the two connectors). You can
combine it with an NI FlexRIO FPGA
module to create an NI FlexRIO digital
instrument (NI PXI-6581R) for a wide
variety of applications from high-speed communication with a device
under test to custom protocol emulation.
You can also use this adapter
module with an NI FlexRIO FPGA module for customized semiconductor testing, electronics testing and interfacing, and implementation and testing of custom digital protocols.
In addition, you can configure the digital I/O lines as custom
counter/timers, pulse-width modulation (PWM) channels, or communication
buses for user-defined protocols or applications requiring serial
triggering. You can even customize the communications with the
onboard DRAM for optimized streaming operations.
National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:
Significant cost savings compared to individual repair incidents
Fault location, diagnostics, and repair by NI any time the system product fails
All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications
NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.
Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
