The DIO is a multimode digital source and capture module. In Low Speed Mode, the DIO provides a 20-bit parallel or 24-bit serial I/O capability running up to 50 MHz. In High Speed Mode, the DIO-200 provides a 16-bit parallel I/O capability up to 200 MHz. In both Speed Modes, the Clock is generated by a low jitter PLL source that can generate clocks from 2 kHz up to 200 MHz. In addition an external clock can be provided. The DIO offers 8 Pattern Bits to the user for DUT synchronization and control. The remaining 8 Pattern Bits are used for control and synchronization of the analog source and capture instrumentation through the ATX backplane. This allows for coherent mixed-signal measurements improving the accuracy of your measurement without need for post-process windowing.
