Freq Offset
Allows you to specify the frequency offset value. When the frequency offset state is ON, an annunciator
is displayed on the main source view to indicate this state to the user.
When the frequency offset is set to zero (0) and you set a new offset value, the displayed frequency value
will change as follows and the RF output frequency will not change:
Displayed value = output frequency + offset value
Where:
output frequency equals the original frequency entered under Source>Frequency>Frequency
offset value equals the value entered under Source>Frequency>Freq Offset
When the frequency offset is set to a value other than zero (0) and you enter a new frequency value under
Source>Frequency>Frequency, the displayed frequency will be the same as the value entered and the RF
output frequency will be equal to the value entered minus the offset value as follows:
Output frequency = entered frequency – offset frequency
Displayed frequency = output frequency + offset frequency
Displayed frequency = entered frequency
Where:
entered frequency equals the frequency entered under Source>Frequency>Frequency
offset frequency equals the value previously entered and set under Source>Frequency>Freq Offset

Allows access to the menus for setting up the available modulation types: “ARB” on page 1173, “AM”
on page 1215, “FM” on page 1216, and “PM” on page 1217.
