FSEM/K21/31 (corresponding to
FSEM/K20/30 with option FSE-B21)
allow frequency range extension by
means of external mixers. Continuous
automatic signal identification, which
is used to suppress unwanted image
frequency bands and mixture prod-
ucts, ensures fast and easy measure-
ments. Due to the built-in diplexer,
three-port as well as two-port mixers
can be used.
The external mixer measurement func-
tion features great ease of operation:
• Definition of frequency range and
harmonics by selection of a
waveguide band
• Definition of all important parame-
ters for each waveguide band
separately
• Frequency-dependent consideration
of mixer conversion loss
• Storage of parameters on hard disk
Measurement functions
• Up to 8 markers
• Marker functions for the direct
measurement of
– phase noise and
phase power density
– NEXT MIN/PEAK, NEXT MIN/
PEAK RIGHT, NEXT MIN/PEAK
LEFT
• Frequency counter with selectable
resolution
• LOW NOISE, NORMAL and LOW
DISTORTION modes to cater for
low-intermodulation and low-noise
operation
• Plotting or printout in background
operation or file saving in standard
graphic format
• Simultaneous display of four traces
• Selectable colour setup
• Numerous level and frequency lines
• Split-screen display with independ-
ent windows
• Quasi-analog display
• Frequency zoom
Overview of configurations and options
The analyzers of the FSE family are of modular design throughout. In the table below the right solution tailored to the needs
of the various applications can be found. Except for the Colour Display FSE-B1 all options can easily be retrofitted (
1) Cannot
be retrofitted, factory-fitted only).
Note: max. two of the options -B4, -B7 can be fitted in FSEM20

• Adjacent-channel power measure-
ment for up to 7 channels
• RMS detector
Operation
A combination of hardkeys and
softkeys makes for extremely fast and
easy operation. The operating conven-
ience based on a wide variety of eval-
uation routines and marker functions
can be accessed via the menus. Com-
plicated tree structures could be
avoided by using menus of lateral
structure and fixed control keys. Com-
plete setups and traces, limit lines as
well as macros can be stored on the
hard disk or on floppy disks.
