Agilent 34980A Mainframe User’s Guide 19
Voltage (DAC) Output
The 34951A module has four independent, isolated analog output
channels that can output dc voltage up to
 16V or dc current up to 
 20 mA. Each DAC (Digital- to- Analog Converter) channel can be used
as a programmable voltage source for analog input control of other
devices. A simplified diagram is shown below.
You can set the output voltage to any value between - 16 Vdc and +16
Vdc, in 500
V steps on any or all four channels.
You can set the output current to any value between - 20 mA and +20
mA, in 630 nA steps on any or all four channels.
