High-performance analyzers
for digital mobile radio and
universal applications
FSEK30 (photo 42756)
Brief description
FSEA, FSEB, FSEM and FSEK are
advanced, high-speed and high-performance analyzers tailored to the
requirements of modern digital communication systems. They can also be
used as general-purpose analyzers for
many applications. High measurement speed, modular design and
excellent technical features make for
an excellent price/performance ratio.
In addition to measurement functions
for digital communication systems,
such as 2 µs sweep time in ZERO
SPAN mode, pretrigger and trigger
delay, gated sweep and adjacentchannel power measurement, these
spectrum analyzers feature a wide
dynamic range, a very low measurement uncertainty of 1 dB and a lownoise synthesizer.
FSE analyzers have low inherent noise
and a wide dynamic range, so that for
instance measurement of GSM power
ramps is no problem.
An extremely wide intermodulationfree dynamic range of 110 dB (with
10 Hz resolution bandwidth) ensures
reliable measurements on highly linear amplifiers as well as correct analysis of broadband complex signals.
From the available frequency ranges,
the basic models 20 and the high-performance models 30 the right instrument can be chosen for every application. Models 20 can easily be
upgraded to give the full range of functions of models 30.
To ensure correct measurement of time
variants or pulse-modulated signals,
the FSE features digital resolution filters (10 Hz to 1 kHz) with a response
corresponding to that of analog filters.
It additionally provides FFT bandwidths down to 1 Hz (models 30).
Main features
• Resolution bandwidths 1 Hz (up to
10 MHz), adjustable in steps of
1/2/3/5/10
• Displayed noise floor down to
−160 dBm (FSEA)
Type Index
• 3rd-order intercept point >+15 dBm
• 1 dB compression point of RF input
>+10 dBm
• Phase noise at 20 kHz from carrier:
down to −123 dBc (FSEA)
• Intermodulation-free dynamic range
110 dB
• Measurement uncertainty up to
1GHz: 1dB
• Headphones connector and built-in
loudspeaker for AM/FM
• Internal RF trigger for GATED
SWEEP measurements
• Speed records:
– Shortest FULL SPAN sweep time
is 5 ms (for 3.5 and 7 GHz span)
with a fully synchronized sweep
– added speed is not at the
expense of frequency accuracy
but even enhances it
– Shortest ZERO SPAN sweep time
is 1 µs (100 ns/div) – ideal for
high-resolution measurements on
pulse edges
– More than 20 sweeps/s – an
optimal prerequisite for fast
alignments or applications in production

From AF to microwave
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 products, ensures fast and easy measurements. Due to the built-in diplexer,
three-port as well as two-port mixers
can be used.
The external mixer measurement function features great ease of operation:
• Definition of frequency range and
harmonics by selection of a
waveguide band
• Definition of all important parameters 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

• 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 independent windows
• Quasi-analog display
• Frequency zoom
Type Index
•Limit lines
• User-configurable menu and keyboard macros
• Adjacent-channel power measurement for up to 7 channels
•RMS detector
Operation
A combination of hardkeys and
softkeys makes for extremely fast and
easy operation. The operating convenience based on a wide variety of evaluation routines and marker functions
can be accessed via the menus. Complicated tree structures could be
avoided by using menus of lateral
structure and fixed control keys. Complete setups and traces, limit lines as
well as macros can be stored on the
hard disk or on floppy disks.
