Measurement time in hours
Level repeatability over time (with random frequency and level changes between measurements)
Precise output level
Precise and stable output levels
are essential in a microwave signal
generator. Furthermore, high resolution
is required when calibrating levels in
measuring receivers. Therefore, the
¸SMF100A offers high-precision,
frequency-response-corrected level
control across the entire level range.
Of course, the ¸SMF100A includes
outstanding absolute level accuracy.
But even more important is its level
repeatability, since absolute errors
can be compensated for by means of
the appropriate corrections. Particu-
larly in the case of repeatability, the
¸SMF100A sets new standards as
shown in the figure below.
High frequency resolution
To meet the high requirements of many
applications in research and science,
the frequency options offer a frequency
resolution of one-thousandth of a hertz
(0.001 Hz) as standard.
Digital frequency and level sweep
The digital frequency sweep makes
it possible to perform frequency
response measurements of microwave
applications. Start and stop frequencies
as well as step times are user-selectable.
A trigger input enables synchronized op-
eration with external equipment.
The level sweep across any level range
makes it possible, for example, to
measure the compression characteristic
of amplifiers or mixers.
Everything in one instrument
The ¸SMF100A base unit with
frequency option included already offers
the essential functions and interfaces.
This basic configuration can be adapted
to meet the requirements of further
applications by adding specific options.
The ¸SMF100A has outstanding
specifications. Additional options for
improving performance are not needed.
This gives you a decisive advantage as
the user. You no longer need to carry out
tedious option configurations in order to
increase performance.
The base unit with frequency options
included consists of the following:
¸SMF100A base unit plus ◆
¸SMF-B122 frequency option
(1 GHz to 22 GHz)
¸SMF100A base unit plus
◆
¸SMF-B144 frequency option
(1 GHz to 43.5 GHz)
With the optional ¸SMF-B2 fre-
◆
quency extension plus one of the fre-
quency options, the frequency range
starts at 100 kHz
This package contains the following as
standard:
Excellent spectral purity
Absolutely no compromises have been
made here. Everything technically fea-
sible has been implemented. Both the
SSB phase noise and the outstanding
suppression of harmonics and nonhar-
monics earn top grades. This is a must
for anyone working in the area of
scalar
network analysis, for example.
