To specify the amplitude
1. Set the reference level, offset and position, using the Ref Level, Ref Level Offset and Ref Level
Position softkeys.
2. Select the level range and the unit for the level axis, using the Range Log and Unit softkeys.
3. Set the scaling, using the Range Linear and/or Grid Abs / Rel softkeys.
4. Set the attenuation, using the RF Atten Manual or RF Atten Auto softkeys.
Softkeys of the amplitude menu
The following table shows all softkeys available in the amplitude menu. It is possible that your
instrument configuration does not provide all softkeys. If a softkey is only available with a special option,
model or (measurement) mode, this information is delivered in the corresponding softkey description.

Ref Level
Opens an edit dialog box to enter the reference level in the currently active unit (dBm, dBMV,
etc).
The reference level value is the maximum value the AD converter can handle without distortion
of the measured value. Signal levels above this value will not be measured correctly, which is
indicated by the IFOVL status display.
