DIAGnostic:DAC:GAIN

Parameters

Comments

DIAGnostic:DAC:GAIN[<channel>] <value> writes the specified value to the calibration gain DAC of the specified channel. This command is a factory diagnostic routine.

Input Signal Required: There must be a signal on the input for this command to work properly. Any offset value set by DAC:OFFSet <voltage> is used by the DAC when the DAC:GAIN command is sent. The gain is set on the specified channel.

DAC Outputs: A positive full scale input combined with a DAC gain value of 255 will result in a +2.5V output from the DAC. A negative full scale input combined with a DAC gain value of 255 will result in a -2.5V output from the DAC. A DAC gain value of 0 will result in 0V output in both cases.

Executable when initiated: NO

Coupled Command: NO

Reset (*RST) Condition: None
