The attenuation can be set in two different ways. This section
describes how to set the attenuation by specifying the attenuation
factor and an offset (called a calibration factor).
“Selecting the Through-Power Mode” on page 70 describes how to
set the attenuation by specifying the power that gets through.
Entering the Attenuation Factor
The attenuation factor is shown at the top left of the display.

2. edit the factor using the Modify keys (see “Using the Modify
Keys” on page 29).
