L4451A Example Program Segments
The programming examples below provide you with SCPI command
examples to use for actions specific to the DAC module.
The slot and channel addressing scheme used in these examples follow

the form 1ccc where ccc is the three- digit channel number. Valid
channels for this module are 001- 004. For information on specific
configurations, refer to the simplified schematic on
page 231 .
For detailed example programs involving multiple drivers and
development environments, refer to the L4400 Product Reference
CD- ROM (p/n 34989- 13601).
Level Mode
Example: Outputting a DC voltage level This command sets the output
voltage level for the specified DAC channels. After setting the desired
level, send the OUTPut:STATe command to close the corresponding
output relay and enable outputs from the specified channels. The
following command outputs +2.5 V DC on DAC channels 1 and 2.
SOURce:VOLTage 2.5,(@1001,1002)
OUTPut:STATe ON,(@1001,1002)
Example: Outputting a current level This command sets the output current
level on the specified channels on the DAC module. After setting the
desired level, send the OUTPut:STATe command to close the
corresponding output relay and enable outputs from the specified
channels. The following command outputs +5 mA on DAC channels 1 and
2 and closes the output relay.
SOURce:CURRent 5E-3,(@1001,1002)
OUTPut:STATe ON,(@1001,1002)
