R&S ESU
– In the time domain (Span = 0 Hz) the generator frequency is derived from the
For the sake of clarity, the formula is also displayed in the table.
The offset setting can be used to sweep in the reverse direction. This can be
achieved by setting a negative offset in the formula above:
Example for reverse sweep:
F
F
F
Numerator = Denominator = 1
→ F
→ F
If the offset is adjusted in a way that the sweep of the generator crosses the 0 Hz
Frequency, it is indicated by the additional statement "via 0 Hz".
Example for reverse sweep via 0 Hz
F

Numerator = Denominator = 1
→ F

• RESULT
The frequency range of the generator resulting from the calculation formula. An
asterisk (*) after the upper limit indicates that the stop frequency of the R&S ESU
must be adapted when the generator is switched on in order not to exceed its
maximum frequency. In the following illustration, this is true for the upper
generator at a stop frequency of 3.2 GHz of the R&S ESU, whereas the lower
generator does not yet require an adaptation:
