Setting the Power Offset Applied to the Sensors
A power offset can be applied to the sensor in the manner described below.
1. Press the Sensor hard key and then the Offset soft key to display the [Offset] dialog.
2. Check that the correct sensor (A or B) is selected.
3. The dialog opens with the “Type” field pre-selected for user entry. Select the offset
type required from the soft keys as detailed below.
Item Meaning
Off No offset is applied to the sensor. This is the default
setting.
Fixed A fixed value specified by the user is applied to the
sensor. Press the down arrow on the keypad to select
the “Offset” item in the dialog and then enter the offset
using the Inc and Dec soft keys, or at the numeric
keypad in the normal manner.
Table The offset value applied is derived from the table that the
user has selected. When “Table” is selected the “Table”
item is enabled in the dialog, enabling the user to enter a
table number from the keypad or press Select Table and
make a selection from the dialog. Refer to Editing the
Sensor Offset Tables
later in this chapter.
Note: A positive offset adds a value to the power readings and can be used to
compensate for attenuators, couplers, limiters, and other lossy devices. A negative value
subtracts a value from the power reading and can be used to compensate for amplification
in the measurement path.
