GENERAL DESCRIPTION

The PAS 9915/AO provides thirty-two, twelve bit analog voltage output channels on a 6U VMEbus card. Eight, quad high speed voltage output DACs, with 10 uSec settling times provide a total of thirty two analog output channels. Voltage output signals are available on the a and c rows of the P2 connector.

Four analog output ranges are available, under program control, allowing the card’s output voltage to be tailored to your application. Bipolar ranges from +/- 10 volts to +/- 5.0 volts and unipolar ranges from 0 to 10 volts to 0 to 5.0 volts are supported. All output ranges provide a minimum of 10 milliamps of output current.

VME systems with A16, A24, or A32 addressing are supported, and data writes of 16 or 32 bits can be used. DIP switches configure the width of the address bus. Data bus width is specified by the instruction type.

External synchronization signals can be connected to the P2 connector through jumper plugs, if required.

Additional features include board identifier registers, control and status register, and DAC loop back registers.
