64-channel, 16-bit PCI digital I/O lab board w/pattern generation
|
|
| |
| 64 digital I/O channels, high-speed pattern generation and digital streaming PCI digital I/O lab board. |
| |
| Characteristics: |
- For PCI bus
- 64 lines (5 V/TTL) of I/O in 16-bit ports
- Generate interrupts on any line
- Four separate high-speed IRQ lines (100 ns)
- User-defined power-up state in 16-bit groups (High, Low, Tri-stated)
- Two Enhanced Synchronous Serial Interfaces (ESSIs) for high-speed devices such as codecs
- Three clock/interrupt lines, three 24-bit counters/timers
- Onboard 16-bit FIFO: 2k samples
- High-speed pattern generation and digital streaming (2 MS/s to and from disk)
- PowerDAQ Software for Windows NT/2000/XP and Linux/RTLinux
