Functional Characteristics
Introduction: The VMIVME-4140 Analog Output Board provides 32 high
quality analog output channels with 12-bit resolution, and can source or
sink 10 mA at ±10 V. Each output has a dedicated D/A Converter (DAC)
assigned to it. The analog outputs can be disconnected from the field
wiring for offline testing. Calibration and self-test are initiated by a
VMEbus system reset or by execution of a software command. During
calibration, a table of offset and gain coefficients is compiled and
stored in RAM. There is an entry for offset and gain corresponding to
each of the 32 channels configured in each of the 6 output voltage
ranges.
Self-Test: Self-Test is run automatically after system reset. The SelfTest Register indicates success or failure and can indicate the channel
which has failed.
