R&S ESCI Tracking Generator - Option R&S FSP-B9
1166.6004.12 4.283 E-1
Frequency-Converting Measurements
For frequency-converting measurements (eg on converter units) the tracking generator is able to set a
constant frequency offset between the output frequency of the tracking generator and the receive
frequency of the R&S ESCI.
Up to an output frequency of 150 MHz the measurement can be carried out in both inverted and normal
positions.

FREQUENCY
OFFSET
The FREQUENCY OFFSET softkey activates the input of the frequency
offset between the output signal of the tracking generator and the input
frequency of the R&S ESCI. Possible offsets are in a range of ±150 MHz in
0.1 Hz steps.
The default setting is 0 Hz. Offsets <> 0 Hz are marked with the
enhancement label FRQ.
If a positive frequency offset is entered, the tracking generator generates
an output signal above the receive frequency of the R&S ESCI. In case of a
negative frequency offset it generates a signal below the receive frequency
of the R&S ESCI. The output frequency of the tracking generator is
calculated as follows:
Tracking generator frequency = receive frequency + frequency offset.
IEC/IEEE-bus command: SOUR:FREQ:OFFS 50MHz
