CompuScope 82GC product introduction
CompuScope 82GC is an 8 Bit, waveform digitizer card for the CompactPCI
TM
Bus, capable of 2 GS/s sampling
on one channel and 1 GS/s sampling on two simultaneous channels.
Recognizing that until very recently, almost all multi-MegaHertz data acquisition was done using Digital Storage
Oscilloscopes under GPIB control, Gage has ported all the features of these DSOs onto the CompuScope card.
This means that you do not have to rethink the solution in terms of a completely unknown data acquisition card.
You can simply develop the data acquisition system as if an oscilloscope were being used, but instead use a
CompuScope card to take advantage of its attractive price and performance.
Of course, CompuScope cards are much more than just another DSO under GPIB control:
•
CS82GC features deep acquisition memory of up to 16 MB.
•
Multi-card Master/Slave systems provide scalability from 2 to 4 channels of simultaneous A/D conversion.
•
Data transfer rates from CompuScope memory to PC memory or extended memory run as high as 80 MB/s
for the CS82GC as compared to a few hundred KB/s for GPIB.
•
CompuScope cards are easier to program, as Software Development Kits (SDKs) are available for C/C++,
MATLAB, LabVIEW and LabWindows/CVI.
•
CompuScope cards are installed inside the CompactPCI
TM
chassis, so there is no external box such as a
DSO.
•
The CS82GC cards have Pre-Trigger Multiple Record as a standard feature, which helps optimize the use of
the on-board memory by stacking data from successive bursts.
•
You can also write software for a multi-card system in which all the cards are not in a Master/Slave
configuration. Drivers supplied by Gage support all these multi-card configurations.
•
In case you do not want to program the CompuScope 82GC card(s), you can use the powerful GageScope
®
oscilloscope software to acquire, analyze and archive signals.
Special features on the CompuScope 82GC include:
•
Bus Mastering
CompuScope 82GC is fully capable of becoming a bus master in order to transfer data at the maximum rate
of 80 MB/s.
A bus Master is a card that can take control of the bus and transfer data to any PCI target device such as
system RAM without any involvement from the CPU.
•
External Clocking
CompuScope 82GC comes standard with external clocking capability that allows synchronization of the
digitizers with an external reference clock.
•
Trigger Output
CompuScope 82GC provides a TTL output on one of the front panel connectors. The rising edge of this
output signifies that a trigger event has been detected on the CompuScope 82GC.
•
Pre-Trigger Multiple Record
Pre-Trigger Multiple Recording allows CompuScope 82G to collect pre-trigger data when the card is in
Multiple Record mode. Up to 32 K points can be captured as pre-trigger data.
