Adlink PCI9820
The Adlink PCI9820 is a high-sampling-speed data acquisition board, available now from Amplicon Liveline.
The Adlink PCI9820 is a high-sampling-speed data acquisitionboard, available now from Amplicon Liveline.
Offering two inputchannels with single-channel sampling at up to 130Msample/s in"ping pong" mode, it is ideal for RF applications suchas radar, vibration analysis, software radio applications, andthose requiring deep memory for storing data.
The board providestwo 14bit A/D pipeline convertors to digitise input signals, bothof which have a sampling rate of up to 65Msample/s.
When usingonly one channel, the signal can be set to "ping pong"between the two convertors enabling the sample rate to bedoubled.
The device has an internal 60MHz timebase for dataacquisition, or alternatively uses an external source for up to65MHz.
Its flexible input configuration includes programmableinput ranges and user selectable input impedance.
Offering a verylarge SDRAM of up to 512Mbyte enables very fast data to bedigitised and stored onboard before being transferred to the hostPC through means of the scatter-gather bus mastering DMA.Flexible triggering functions are also available, using bothanalogue and digital triggers.
The analogue trigger hasprogrammable trigger thresholds on rising or falling edges ofboth input channels.
With post-, pre-, delay and middle triggermodes, data can be captured at any moment.
The PCI9820 can belinked with up to four other identical boards, which enables themto acquire data from one trigger signal.
A synchronisation busroutes the timing and trigger signals between devices.
ThePCI9820 can be used with Windows 98, NT, 2000, XP and Linuxoperating systems and has drivers for LabView, VB, C++ and Delphialong with ActiveX controls.
A PXI version of this board will beavailable soon.
Amplicon provides full technical support for theboard, and can also give customers the added benefit of beingable to recommend a complete package which could includeindustrial computer and data communications products, in orderthat a total solution for each individual application isprovided.
