Figure 6-60. Typical
Setup for a Frequency Offset Measurement
Frequency
Offset In-Depth
Description
The source and receiver operate at two different frequencies in frequency offset operation.
The difference between the source and receiver frequencies is the frequency that you
specify.
The two user-defined variables in frequency offset are the receiver frequency, and the offset
frequency. The source frequency is automatically set by the
and equals
receiver frequency IF + or IF
The Receiver Frequency. You
can choose a CW value or start and stop values for the receiver
frequency. The stimulus values, which appear on the analyzer display, will affect only the
receiver.
The
Frequency
This frequency value is the difference between the source and
receiver frequencies.
Note
The analyzer’s source locks to the receiver the frequency, regardless of
the offset value you selected.
the source is phase-locked and sweeping, the analyzer’s source frequency
is not known precisely. As the frequency changes, the source tracks it to
maintain the receiver start/stop or CW frequency that you requested.
Frequency Hierarchy.
The source frequency can be greater than or less than the
frequency. That is, the analyzer can measure either the lower or upper of the two IF mixing
products when it is in the frequency offset mode.
Frequency
Ranges. Receiver frequency range: 300
to 3
(or 6
with Option 006)
Compatible Instrument Modes and Sweep
Types. Frequency offset is compatible with all
sweep types in the network analyzer mode.
