The old command
[:SENSe]:ADC:DITHer AUTO
is aliased to
[:SENSe]:ADC:DITHer:AUTO[:STATe] ON; because of this, the [:SENSe]:ADC:DITHer function
cannot be a true Boolean, so the query, [:SENSe]:ADC:DITHer? returns OFF or ON (not 1 or 0 like
a true Boolean)

Auto
Sets the ADC dither to automatic. The analyzer then chooses the dither level according to which is
most likely to be the best selection, based on other settings within the digital IF.
When in Auto, the analyzer sets the dither to Medium whenever the effective IF Gain is Low by
this definition of IF Gain = Low:
•
When Sweep Type = Swept, IF Gain = Low whenever Swept IF Gain is set to Low Gain, whether
by autocoupling or manual selection.
•
When Sweep Type = FFT, IF Gain = Low whenever FFT IF Gain is set to "Low Gain," which
cannot happen by autocoupling.
Whenever the IF Gain is not low by this definition, Auto sets the dither to Off.
