●
Synchronization of the generator to the analyzer when using an internal analyzer.
If the generator and analyzer of the R&S UPP are operated together, a generator
sweep should always be synchronized to the analyzer. This ensures that the gen-
erator is advanced precisely at the point when all measurement results are availa-
ble and have settled (where applicable also frequency, level monitor and input
measurements on the active channels).
●
Reducing the measurement points for low frequencies . Low frequencies require
longer measuring times than higher frequencies. The sweep axis should therefore
be divided in such a way that only a few low tones are used. This can be achieved
in the following ways:
Linear instead of logarithmic spacing
Increasing the lower sweep limit
List sweep
●
Reducing the measurement points. The duration of the sweep cycle increases
more or less linearly with the number of sweep points. The list sweep enables you
to set the distances between the individual sweep points and thus to carry out a
burst at locations of particular interest without increasing the total number drasti-
cally.
List sweep
Avoiding an unnecessarily small step size
Avoiding an unnecessarily large number of sweep points
Minimizing the measurement time
When using the internal analyzer, the required measurement time depends on the
selected measurement functions. Generally speaking, every measurement function
used should wherever possible be configured for high measurement speed; this, of
course, depends on the specific measurement function. For this reason, only a few
generally applicable rules are given below:
●
Only activate those measurement channels which are to be measured. An uncon-
nected measurement input can increase the measurement time considerably
because measurement is only completed when a measured value exists for this
channel. A number of measurement functions require considerably more time to
