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)
