Overview
Key Features
Intelligent DAQ is multifunction data acquisition that features user-
defined onboard processing as well as complete flexibility of I/O
timing and triggering. You can configure all device functionality by
creating NI LabVIEW block diagrams with the LabVIEW FPGA Module.
Your block diagram executes in hardware, giving you direct, immediate
control of all I/O signals on the PXI or PCI device. With R Series and
LabVIEW FPGA, you can configure user-defined hardware for a wide
variety of applications requiring precise timing and control such as:
• Data acquisition with flexible triggering and onboard processing
• High-speed analog and discrete control loops
Through programming in LabVIEW FPGA, you can control each of the
I/O signal lines independently or synchronize a line with other channels.
You can configure the digital I/O lines as custom counter/timers, PWM
channels, or communication buses for user-defined protocols. All
multifunction R Series devices have dedicated analog-to-digital
converters/digital-to-analog converters on every analog I/O channel.
This offers specialized functionality such as multirate sampling and
individual channel triggering, which are beyond the capabilities of
typical data acquisition hardware. You can sample every analog input
channel on an R Series device simultaneously at rates up to 750 kHz,
and you can program every analog output on an R Series device to
update simultaneously at rates up to 1 MHz. You can also store your
compiled LabVIEW FPGA application in the onboard flash memory of
any R Series device and configure it for automatic loading and/or
execution at power up.
• Pulse-width modulation (PWM) and encoder interfacing
• User-defined digital communication protocols
• Custom counters with up to 64-bit resolution
• Hardware-timed decision making at 40 MHz
