3 System Overview
98 Keysight 34970A/34972A User’s Guide
Control Output
In addition to signal routing and measurement, you can also use the 34970A/
34972A to provide simple control outputs. For example, you can control external
high-power relays using the actuator module or a digital output channel.
The multifunction module
The multifunction module (34907A) 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 which are described in more detail starting on page 96.
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.
