DAC Output Operations

The multifunction module (HP 34907A) has two low-noise analog outputs capable of outputting calibrated voltages between ±12 volts with

16 bits of resolution. Each DAC (P”z”t44Mz Oxx) 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 “ 04”

and “ 05”, where 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; ”t y

Each DAC channel is capable of 10 mA maximum output current.

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 that a from the front panel resets only the DAC currently selected (both channels are not reset).

Sctxt”: After selecting the desired DAC, press

to edit the output voltage. Press again to output the specified voltage from the DAC channel.

exx Vxytvx bxt”: The following command outputs +2.5 Vdc from the DAC on channel 05.
