[ADC Dither
Auto Man]
● Menu description: to control opening/closing of ADC dither of the frequency acquisition circuit in the
analyzer. Under default mode, the signal/spectrum analyzer will automatically control whether the ADC
Dither is ON based on current working condition. When the ADC Dither is under Auto mode, the ON or
OFF status depends on the span, resolution bandwidth and sweep type (continuous swept or step sweep);
when it is continuous swept, the ADC Dither status will force to switch to Auto and turns off; when it is
step sweep, under Auto mode, if the span is 2 MHz or below, the ADC Dither is ON; if the span is below
2 MHz, the ADC Dither is OFF. Under Auto OFF mode, if the span is above 2 MHz, turning on the ADC
Dither may affect the measurement results based on selected dither status.
You can access the submenu for manual control You can access the submenu for manual control.

[Noise Correction
On Off]
● Menu description: activate or deactivate the noise correction function. When the noise correction
function is activated, 4051 first implements the noise correction under the current apparatus state to
obtain the correction data and then deletes the apparatus background noise from measuring result so as to
improve the measuring flexibility and dynamic range. When the measuring state of apparatus changes,
such as resolution bandwidth, frequency width, center frequency and so on, 4051 will implement the
noise correction under the new measuring state.
