Setting the Reference Level
The reference level is set at the top of the graticule display. Measurements can only be made on signal peaks
that are below the reference level, so it is important to determine the approximate level of the signal peak and
appropriately set the reference level higher than the signals being measured.
1. Press the Amp icon on the main menu bar, or press the Amplitude key on the instrument front panel, to
display the Amplitude menu below:
2. Press in the Reference Level parameter field and use the keypad to enter the desired reference level, then
select the appropriate amplitude terminator from the fly-out menu.
