PAS 9740/DO : 16 Channel VME Pattern Generator Card

Links to printable product info:

• Product Manual

Precision Analog System's PAS 9740/DO "Pattern Generator" card outputs arbitrary data patterns on its sixteen data lines, based on information that is programmed into its FIFO memory. These data patterns can be programmed to change once every microsecond, which allows the card to simulate high speed pulse output devices, such as crankshaft position sensors. On board sequencer logic compares the time value that is stored in the FIFO with the time of the card's 1 microsecond clock.  When the times compare, the outputs are updated to the data value associated with that time.

The card contains FIFO's that are 32 bits wide and 512 locations deep.  The 1 microsecond clock registers are 32 bits wide.  In systems that contain several boards, one board can be designated the master and used to enable all of the other clock registers.  All of the clock registers can be incremented from the VME system clock or from their onboard oscillators.

Key Features

• Generates 16 channel output data pattern based on data loaded in on-board FIFOs

• 32 bit wide by 512 location deep FIFO buffers card from VME bus

• 1 MHz time base allows output data patterns to be generated with 1 uSec resolution

• RS-232 voltage level outputs with output enable / disable function

• VME format 160 mm x 233 mm card size

• VME access A32, A24, A16, D32, D16 slave

• Sysfail and board access LEDs, board identifier PROM

• Loop back Test Register allows verification of VME bus interface

• The PAS 9740/DO can be customized to meet the requirements of your application.   Please contact PAS for further information.
