Board uses the full bandwidth of a PCI Express x4 lane to support up to 1000Mbit/s image acquisition rates and to provide two independent Gigabit Ethernet ports.
Acquisition cards perform many functions
Adlink's latest data acquisition cards provide a 10% increase in performance over the company's previous generation of multifunction DAQ cards.
When used with a bandpass filter and down conversion technology, the PXI-9820 can capture and analyse IQ signals in digital communications.
The PXI-9820 is a high speed, high resolution, high capacity DAQ card equipped with two analogue inputs and two synchronous digital inputs (SDI).
The product provides 14bit resolution and can maintain single- and dual-channel sampling rates of 130 and 65Msample/s, respectively.

Optimised for stability and packaged in a rugged format, the cPCI-3920 is built to withstand even harsh environment.
Mezzanine card brings server-class performance
AdvancedMC processor module combines a dual-core 64bit low-power processor and server-class 3100 chipset to optimise power consumption, computing power and I/O bandwidth.
Its input ranges (-1 to 1V or -5 to 5V) are selected via software and input impedance (50ohm or 1.5Mohm) is selected through solder points.
The PXI-9820 offers maximum analogue input flexibility for multiple front-end applications.
The PXI-9820 is equipped with standard SODIMM SDRAM for high-speed storage and easy upgrades.
The module exceeds the 33MHz, 32bit PCIbus bandwidth through its single-channel dataflow, so memory flexibility is very important.
The new product comes equipped with 128Mbyte of RAM, expandable to 512Mbyte, which can record several seconds of data at a single channel sampling rate of 60Msample/s.
Besides using SDRAM for storage media, the PXI-9820 provides DMA transmission to instantaneously transfer data to system memory when acquisition bandwidth is less than that of the PCIbus.
Other DAQ module manufacturers often use onboard RAM, whereas Adlink's PXI-9820 uses standard RAM modules, making upgrades cheap, easy, and simple.
The PXI-9820 is equipped with several triggering methods: software, analogue and digital.
Analogue triggering can be configured through numerous options, and digital triggering supports rising edge and falling edge triggering.
The PXI-9820 also implements PXI star trigger and PXI trigger bus to route timing and trigger signals between one or more PXI-9820 and other PXI modules.
Users can also choose between using the internal clock, the output of the onboard PLL with a reference clock from an external clock input, or the PXI 10MHz reference clock to synchronise multiple PXI modules in a system.
The PXI-9820's two synchronous digital inputs (SDI) allow digital input to be synchronously sampled with analogue input, making it ideal for mixed signal acquisition.
Like the Adlink PXI-2000 series, the PXI-9820's auto-calibration feature adjusts the gain and offset to a specified accuracy, eliminating the need to manually calibrate modules.
The PXI-9820 is available from stock.
