The Level function has 4 sub-menus.
Pressing the

Reference Level, that can be increased or reduced by steps of 5dB within
the range +60 dBµV to 130 dBµV (-45 to 25 dBm); in operating modes
Analyzer and Manual the min.-max. values of the reference level are in
function of the input attenuator and preamplifier settings.
The
Input button opens a submenu which is dedicated to the setting of the
input attenuator and to switch on-off the built-in preamplifier.
The PMM 9010 receiver takes automatically into account the settings of all
the Input parameters and always displays the correct value of the level.
The User is not required to make any correction to the readings.
