Brief description
FSEA, FSEB, FSEM and FSEK are
advanced, high-speed and high-per-
formance analyzers tailored to the
requirements of modern digital com-
munication systems. They can also be
used as general-purpose analyzers for
many applications. High measure-
ment 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
µ s sweep time in ZERO
SPAN mode, pretrigger and trigger
delay, gated sweep and adjacent-
channel power measurement, these
spectrum analyzers feature a wide
dynamic range, a very low measure-
ment uncertainty of 1 dB and a low-
noise 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 intermodulation-
free dynamic range of 110 dB (with
10 Hz resolution bandwidth) ensures
reliable measurements on highly lin-
ear amplifiers as well as correct anal-
ysis of broadband complex signals.
From the available frequency ranges,
the basic models 20 and the high-per-
formance models 30 the right instru-
ment can be chosen for every applica-
tion. Models 20 can easily be
upgraded to give the full range of func-
tions of models 30.
To ensure correct measurement of time
variants or pulse-modulated signals,
the FSE features digital resolution fil-
ters (10 Hz to 1 kHz) with a response
corresponding to that of analog filters.
It additionally provides FFT band-
widths 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)
• 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
1 GHz: 1 dB
• 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 µ s (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 pro-
duction
