¸SMF100A Microwave Signal Generator

Suitable for all

applications

Scalar network analysis

A common task in R&D or production is
the adjustment of filters or the character-
ization of components. With its integrated
List mode or its optional analog ramp
sweep, the ¸SMF100A directly offers
two ways of performing the measurements
quickly and accurately. A major advantage
in both modes is that frequency and
linearity errors can be eliminated, as
frequency generation is implemented
in a synthesized (digital) manner.

A third brand-new approach to scalar
network analysis is provided by the
power sensor connectivity of the
¸SMF100A plus the ¸SMF-K28
power analysis option.

List mode
Especially when the ¸SMF100A mi-
crowave signal generator is used together
with a Rohde & Schwarz spectrum analyzer
(¸FSP-B10 option), scalar network
analysis can be performed selectively and
very quickly. The distinguishing aspect
is a large dynamic range with which,
for example, filters in the passband and
stopband can be measured even at small

levels. An adjustable frequency offset is
also available for measuring frequency-
converting DUTs. (Note: The List mode
in combination with the ¸FSP-B10
option requires that the ¸SMF-B83
removable GPIB option be installed.)

Analog ramp sweep
For the "realtime adjustment" of filters
or components, very high sweep speed
and sweep accuracy are required. The
¸SMF100A meets this requirement
by means of the optional ¸SMF-K4
analog ramp sweep. This solution
furthermore offers a higher frequency

Scalar network analysis on a external bandpass filter (with ¸SMF-K28 power analysis option plus
¸NRP-Zx power sensor)

resolution than the List mode mentioned
earlier.

Scalar network analysis with an
¸NRP-Zx power sensor
In the absence of spectrum or network
analyzers scalar network analysis can be
performed by means of the ¸SMF100A
microwave signal generator with the
¸SMF-K28 power analysis option
plus an ¸NRP-Zx power sensor. One
example is to measure the passband
characteristic of a bandpass filter.
