ration. (Note that the frequency is defined as the unsigned value of the equation, thus a
negative frequency is not possible.)
Example: Example for reverse sweep
F
AnalyzerStart
= 100 MHz
F
AnalyzerStop
= 200 MHz
F
Offset
= -300 MHz
Numerator = Denominator = 1
→
F
GeneratorStart
= 200 MHz
→
F
GeneratorStop
= 100 MHz
If the offset is adjusted so that the sweep of the generator crosses the minimum gener-
ator frequency, a message is displayed in the status bar ("Reverse Sweep via min. Ext.
Generator Frequency!").
Example: Example for reverse sweep via minimum frequency
