Esc key to return to normal operation without changing the setting.
Trace Label
On Off: Press this submenu key to toggle the trace labels On or Off.
Meas Gain Range: Press this submenu key to open the Mode Menu.
Select Auto or Fixed.
Auto: Press this submenu key to set the Measurement Gain Range
Mode to Auto. In this mode, the instrument adjusts the gain
automatically to provide the best overall system performance
(dynamic range and high level noise).
Fixed: Press this submenu key to set the Measurement Gain Range
Mode to Fixed. In this mode, the gain of the instrument is always set to
the low gain setting. For most applications, Auto mode is
recommended. For certain types of filter measurements (mostly in the
range less than 500 MHz), the instrument may toggle between low
gain and high gain modes as the signal level rises from the noise to
the pass band of the filter, resulting in extra ripple. Setting the Gain
Range to fixed may address that problem.
