Output Attributes:Digital Gain

Short Name: Digital Gain

Specifies a factor by which the signal generator should digitally multiply generated data before converting it to an analog signal in the DAC. For a digital gain higher than 1.0, the product of digital gain times the generated data must be inside the range ±1.0 (assuming floating point data). If the product exceeds these limits, the signal generator clips the output and an error results.

Some signal generators support both digital gain and an analog gain specified with the Amplitude property or Arbitrary Waveform Gain property. Digital gain has the advantage that it can be changed during generation without glitches that may occur when changing analog gains, due to relay switching. However, the output resolution of the DAC is a function of analog gain, so only analog gain makes full use of the resolution of the DAC.

Default Value: 1.0
