15 Power Control Measurement
Source
Where:
reference frequency equals the original RF frequency entered under Source>Frequency>Frequency and
set as the reference frequency
entered frequency equals a new value entered under Source>Frequency>Frequency
In addition, the displayed frequency value will be the same as the value entered under
Source>Frequency>Frequency.
If Freq Reference is set to ON with a reference value set, entering a value under
Source>Frequency>Frequency and pressing Set Frequency Reference will add that value to the existing
Freq Reference value.
If you wish to change the reference frequency value to the new value entered under
Source>Frequency>Frequency, first you must set Freq Reference to OFF and then press Set Frequency
Reference.

Freq Reference
This key allows you to toggle the state of the frequency reference. When the frequency reference state is
ON, an annunciator is displayed on the main source view to indicate this state to the user.
When you use a frequency reference, the signal generator outputs a frequency that is set relative to the
reference frequency by the value entered under Source>Frequency>Frequency as follows:
Output frequency = reference fre entered frequency
Where:
reference frequency equals the original RF frequency entered under Source>Frequency>Frequency and
set as the reference frequency
entered frequency equals a new value entered under Source>Frequency>Frequency
