Vector analysis for digital
communication
The analyzers of the FSE family combine
the capabilities of high-end RF or microwave spectrum analysis with those of
universal digital-signal demodulation and
analysis. This becomes possible with the
vector signal analyzer option. The spectrum analyzer function offers the wide
dynamic range necessary for many measurements on digitally modulated signals
(e.g. burst measurements), and the vector
signal analyzer option adds demodulation
capability to bit stream level for signals
such as
◆ 1 dB compression point of RF input
+10 dBm
◆ Phase noise at 10 kHz from carrier:
–123 dBc (Hz) (typ.) (FSEA 30)
◆ Total level measurement uncertainty
up to 1 GHz <1 dB, up to 7 GHz 1.5 dB
◆ AM/FM audio demodulator (with
built-in loudspeaker and headphones
connector)
Modularity safeguards investments

design throughout. From the wide variety
of options, you can choose exactly those
needed for your particular application
(see also fold-in page).
You thus get an instrument tailor-made to
your requirements and pay for no more

High speed increases efficiency
The high speed of FSE increases efficiency in development and production:
◆ FSE features a minimum full-span
sweep time of 5 ms (FSEA/B) with a
fully synchronized sweep. This means
that added speed is not at the expense of frequency accuracy but even
enhances it
◆ The shortest zero-span sweep time is
1 µs (100 ns/div) – ideal for highresolution measurements on pulse
edges
◆ Up to 25 sweeps per second is an op-
timal prerequisite for rapid and easy
alignments and for applications in
production
With its high measurement speed and
great ease of operation, FSE will solve
even highly complex measurement
tasks in next to no time.

FSE makes measuring easy for you
through a large number of convenient
test functions:
◆ 4 markers, 4 delta markers
◆ Marker functions for direct measure-
ment of
– phase noise and noise power
density
– NEXT MIN/PEAK, NEXT MIN/PEAK

◆ Hardcopy at a keystroke
◆ Simultaneous measurement of four
active traces
◆ Level, frequency and user-definable
limit lines as evaluation help with
pass/fail information
◆ Split screen with independent mea-
surement windows
Frequency accuracy –
to the point
Tuning on FSE is absolutely synchronous
to the reference frequency for each span
including full span. This means that every
point on the frequency axis is determined
with the accuracy of the internal reference frequency and the pixel resolution.
Thus, when reducing the span for
detailed signal analysis, the tiresome
readjustment of the center frequency is
no longer needed.
FSE in its basic configuration includes an
AM/FM audio demodulator. Unknown
signals can easily be identified via headphones or the built-in loudspeaker. Modulation measurements are possible using
the optional Vector Signal Analyzer FSEB7.
Limit lines facilitate checking whether
results are within predefined tolerances.
Virtually any number of limit lines can be
defined with high accuracy by means of
50 points to meet even the most exacting
requirements.
Scalar network analysis
The optional tracking generators (see
data sheet for FSE-B8/9/10/11
PD 0757.3434) are an ideal tool for determining frequency response, attenuation
or VSWR and feature the following characteristics:
◆ Wide dynamic range for attenuation
measurements (up to 120 dB)
◆ Frequency range from 9 kHz to
3.5/7 GHz
◆ Frequency offset up to ± 200 MHz for
measurements on frequency-converting modules
The tracking generators with built-in I/Q
modulator are ideal for generating digitally
modulated signals. An external two-channel Arbitrary Waveform Generator (e.g.
AMIQ from Rohde& Schwarz) serves as
modulation source.
By adding the optional Vector Signal Analyzer FSE-B7, FSE can be expanded to a
test assembly enabling direct measurement of the influence of amplifiers or filters on phase error for instance.
Operation – as you like it
Despite their comprehensive functionalities the analyzers feature great ease of
operation. Basic functions and frequently
used help tools such as markers can be
called at a keystroke. The full operating
convenience based on a wide variety of
evaluation routines and marker functions
can be accessed via the menus.
All essential parameters and results can
be seen at a glance. All test data, scale
factors and setting parameters are logically arranged and therefore easy to find.
Setups, traces and graticules displayed in
colour make for error-free analysis of
complex results.
All models are equipped with a large
24 cm (9.5") TFT colour display with VGA
resolution (640 x 480 pixels).
The USER key allows the FSE operation to
be tailored to your specific requirements.
With this key, you can compile the functions mainly needed for your measurement tasks, which does away with frequent menu changes and speeds up measurements on the whole.
Test results –
perfectly documented
FSE affords uncomplicated logging of
results. It supports a wide variety of printers such as:
◆ Printer with HP-PCL4 and HP-PCL5
◆ HP Deskjet/HP Laserjet
◆ Postscript
Print files cannot only be output via an
interface but can also be stored on diskette or the internal hard disk. With PCX,

Moreover, with optional Controller
FSE-B15 and a second IEC/IEEE-bus card
(option FSE-B17), FSE can be used as a
controller for test systems, thus eliminating the need for further units and saving
space in the system cabinet.
Page 9
Calibration routines
Built-in calibration routines ensure that
FSE remains within defined tolerances
and thus maintains its accuracy of measurement. The routines are not performed
automatically by the instrument but can
be started by the user, thus avoiding
ongoing measurements to be interrupted.
The results of calibration routines are output by FSE in the form of comprehensive
correction tables. Comparing these tables
over an extended period of time, the user
can detect changes early and take corrective steps in time. This enhances confidence in the unit’s reliability and measurement accuracy.
A particular asset in system applications
is the internally selectable, high-precision
level calibration source, which reduces
the number of cables required.
Selftest –
the built-in diagnostic system
The instrument selftest rapidly locates
any faults down to module level. Defective modules can be replaced nearly without adjustments or extra test equipment
being required. This in conjunction with
the quick spare parts service from
Rohde&Schwarz reduces any repair or
downtime costs that might arise. The low
operating costs go easy on your budget.
Modular design –
easy retrofitting of options
The modular concept of the most important options such as Vector Signal Analyzer and 7 GHz Frequency Extension, as
well as the alignment-free incorporation
of the remaining options make it possible
to retrofit the instrument with a minimum
of downtime or installation costs being
involved.
Quality management at
Rohde&Schwarz
Lasting customer satisfaction is our primary objective. The quality management
system of Rohde&Schwarz meets the
requirements of ISO9001 and encompasses largely all fields of activity of the
company.

General-purpose RF measurements
Two-tone measurements (1)
FSE facilitates intermodulation measurements with its wide intermodulation-free
dynamic range, which reduces measurement errors. This feature is enhanced by
the LOW DISTORTION mode, which
ensures optimum RF attenuation. Evaluation of results is rapid and easy by means
of markers and delta markers.
Harmonics measurements with split
screen (2)
The split-screen function has been provided for the convenient analysis of
results. In harmonics measurements, for
example, the fundamental and the first
harmonic can be displayed simultaneously with high resolution.
Low noise floor even in the microwave
range (3)
Thanks to fundamental mixing FSEM features the same constantly low noise floor
as an RF analyzer up to 26.5 GHz. As a
consequence, FSEM offers not only a
wide dynamic range, but also a considerably increased speed for measuring small
signals in the microwave range: Larger
resolution bandwidths and high sensitivity reduce sweep time while maintaining
the S/N ratio. This is of great advantage
when measuring spurious and harmonics
alike.

FSE phase noise as a function of carrier
spacing (4)
With a phase noise of –123 dBc (Hz) at
10 kHz from the carrier, the synthesizer
incorporated in FSEA 30 is ideal for measuring the phase noise of oscillators or
the adjacent-channel power of radio
equipment.

Noise Measurement Software FS-K3 (5)
FS-K3 turns your FSE into a noise measurement system offering the advantages
of an analyzer (see also data sheet
PD 0757.2380):
◆ Wide variety of resolution bandwidths
for every application, even for measurements on narrowband DUTs
◆ If results are doubtful, the analyzer al-
lows the test setup to be checked for
radiated interference or nonharmonics
◆ Lower frequency limit of 100 kHz
◆ Measurements on frequency-convert-
ing DUTs supported by external
generator
Phase Noise Measurement Software
FS-K4 (6)
With FS-K4 (see also data sheet
PD 0757.4201), FSE can be used as a
phase noise analyzer. The phase noise of
an input signal can easily be measured
over several decades and displayed on a
logarithmic frequency axis. The residual
FM or PM can be determined conveniently within freely selectable limits.
RMS detector: power measurement
without correction factors (7)
In the example, the power of a CDMA signal in the transmission channel and the
adjacent channels is measured. The two
traces show the influence of the DUT on
the adjacent-channel power. Measuring
power and adjacent-channel power of
digitally modulated signals requires a
spectrum analyzer to be equipped with
special detectors and test routines. FSE is
the first spectrum analyzer that features a
real power detector with wide dynamic
range – the RMS detector. Like a thermocouple power meter, this detector guarantees stable and accurate test results
without any correction factors. Considerably higher test throughput is achieved
than with the usual sample detector.
Using the available default settings for
ACP measurements in line with common
standards (NADC, PDC, CDMA, WCDMA,
etc) precise test results are obtained easily and fast.

Mobile radio –
digital and analog
RF power trigger replaces external trigger (no illustration)
An internal broadband level detector
(center frequency ±50 MHz) with a fixed
switching threshold of approx. –20 dBm
at the first mixer is used as a trigger
source. With this detector it is possible,
for example, to perform "spectrum due to
switching" and "spectrum due to modulation" measurements to GSM specifications without an external trigger. The
detector replaces the external trigger
needed in the gated sweep mode.
Gap sweep: simultaneous measurement of pulse rise and fall times with
high time resolution (8 and 9)
The fast sweep time of 100 ns/div as well
as the gap sweep and pretrigger functions of Spectrum Analyzer FSE make it
possible to measure the rise and fall
times of an RF pulse simultaneously and
with high time resolution. The center of
the pulse, which is of no interest, is
blanked. Even at a resolution bandwidth
of 1 MHz FSE offers a dynamic range of
over 80 dB thanks to the high 1 dB compression point of +10 dBm.
10
11
Gated sweep (10 and 11)
The gated sweep function is indispensable for analyzing TDMA signals used in
modern communication systems. With
this function, the spectrum of burst signals can be investigated without any
interference being caused by switching
the signals on and off. The selected gate
time determines over what interval a
pulse is to be analyzed. Selection of the
gate time is easy and convenient in the
time domain display (zero span) of the
pulse.

Vector signal analysis
Universal analysis of digital signals
Spectrum Analyzer FSE in conjunction
with the optional Vector Signal Analyzer
FSE-B7 is ideal for demodulating and
measuring digitally modulated signals
with frequencies up to 3.5 GHz, 7 GHz,
26.5 GHz or 40 GHz. This universal tool
offers a wide variety of settings:
◆ Demodulation of all common mobile-
radio signals
◆ Symbol rates up to 2 MHz
◆ Typ e of filter
◆ Roll-off factor or BT product of filter
◆ Synchronization bit sequences
◆ Predefined, application-specific set-
tings for all common standards, e.g.
GSM, PCS1900, NADC, CDMA (IS95)
Versatile display of results
◆ Inphase and quadrature signals
◆ Magnitude and phase
◆ Vector and constellation diagrams
◆ Eye and trellis diagrams
◆ Sum fault: amplitude, frequency,
phase, vector
Power ramp measurements
To perform power ramp measurements to
standards on TDMA systems such as
GSM or DECT, reference must be made to
synchronization sequences (pre- or midamble) in order to establish a time reference. Making such measurements to
standard is not possible using conventional analyzers – but it is no problem
with FSE!
Accurate AM, FM and PM measurements
Featuring high-accuracy measurement of
the modulation depth and frequency
deviation coupled with the display of
demodulated signals in the time domain,
FSE not only enables testing of analog
and dual-mode radio equipment but also
the determination of the transient
response in frequency and amplitude (see
data sheet PD 0757.2167).
Spectrum Analyzer FSE and the
optional vector signal analyzer provide
universal test capabilities in one unit.

Impedance50 Ω
For maximum bandwidth set instrument to 10 MHz RBW. The output level is a
function of the mixer level, which equals the input signal level minus the set RF
attenuation.
The typical loss between mixer level and IF output is 2 dB for FSEM/K, and 0 dB
for FSEA/B.
