DAC Output Operations

The multifunction module (34907A) has two low-noise analog outputs
capable of outputting calibrated voltages between ±12 volts with 16 bits
of resolution. Each DAC (Digital-to-Analog Converter) channel can be
used as a programmable voltage source for analog input control of other
devices.
• On the multifunction module, the DAC channels are numbered "s04"
and "s05", where s represents the slot number.
• You can set the output voltage to any value between +12 VDC and -12
VDC, in 1 mV steps. Each DAC is earth referenced; it cannot float.
• Each DAC channel is capable of 10 mA maximum output current.
Note: You must limit the output current to 40 mA total for all three
slots (six DAC channels).
• A Factory Reset (*RST command), Instrument Preset
(SYSTem:PRESet command), and Card Reset (SYSTem:CPON
command) from the remote interface will reset both DACs to 0 VDC.
Note: A
from the front panel resets only the DAC currently
selected (both channels are not reset).
• Front-Panel Operation: After selecting the desired DAC, press
edit the output voltage. Press
voltage from the DAC channel.
• Remote Interface Operation: The following command outputs +2.5
VDC from the DAC on channel 05.
