Keysight DAQ970A User Guide

The multifunction module
The multifunction module (DAQM907A) adds two additional control output capabilities to the system:
digital output and voltage (DAC) output.
The multifunction module also contains digital input and event totalizer capabilities. For more details, see
"The Multifunction Module".
Digital output
The multifunction module has two non-isolated 8-bit input / output ports which you can use to output
digital patterns. Each port has a separate channel number on the module and contains 8-bits. You can
combine the two ports to output a 16-bit word.
Voltage (DAC) output
The multifunction module has two analog outputs capable of outputting calibrated voltages between ±12
V with 18 bits of resolution. Each DAC (Digital-to-Analog Converter) channel can be used as a pro-
grammable voltage source for analog input control of other devices. A simplified diagram is shown below:
