6 Input/Output
6.1 RF Source
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 frequency - 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
In addition, the displayed frequency value will be the same as the value entered
under Source>Frequency>Frequency.
NOTE
If Freq Reference is ON with a reference value set, entering a value under
Source, Frequency, Frequency and pressing Set Frequency Reference adds
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 set Freq Reference OFF then press
Set Frequency Reference.

6.1.9.5 Freq Reference
Lets you 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 frequency + 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,
