Precompliance Test Receiver/Spectrum Analyzer

R&S®ESPI...

◆ Optimized operating concept owing to

decades of experience in EMI test
receiver development

◆ Very high measurement speed

◆ High measurement accuracy

With the two ¸ESPI test receiver
models, the well-known advantages of
the ¸ESIB high-end compliance test
receivers/analyzers have been systemati­cally implemented for the upper middle­end.

Due to a common platform system, the
user has the additional benefits of the
¸FSP spectrum analyzer family which
is already in place. These benefits by far
exceed the capabilities and functions of
conventional precompliance test equip­ment.

The ¸ESPI defines the vital criteria,
such as functionality, measurement speed
and accuracy for middle-end equipment.

The use of innovative techniques, such as
the VLSI frontend and largely digital
signal processing, together with ASICs
developed by Rohde & Schwarz, has
resulted in a product with top-class
specifications and high reliability.

Precompliance has a name: R&S®ESPI3 and R&S®ESPI7

Features

The ¸ESPI 3 and ¸ESPI 7,
which are suitable for all commercial EMI
standards in line with CISPR, EN, ETS,
FCC, ANSI C63.4, VCCI and VDE, have
been specially designed for precompli­ance measurements in development. The
aim is to perform EMC diagnostic mea­surements on the devices under test as
quickly as possible and as accurately as
necessary and to document the results.

9 kHz 3 GHz

The final compliance test will then be
purely a formality. The advantages of test
receiver accuracy and selectivity com­bined with the measurement speed of a
spectrum analyzer define the crucial per­formance features for a new class of test
receivers.

¸ESPI 3: 9 kHz to 3 GHz
¸ESPI 7: 9 kHz to 7 GHz

These two models make it possible to
take products through the critical stages
of development and the EMC test plan
and still be on schedule for approval and
market launch.

¸ESPI 3

¸ESPI 7

7 GHz

The precompliance measuring instru­ments from Rohde & Schwarz provide the
functions that are required for in-house
test sequences:

◆ Manual measurement of EMI spectra

owing to the receiver-oriented
operating concept

◆ Semi-automatic measurements with

predefined scan and sweep tables
allowing interactive interruption

◆ Individual evaluation of critical fre-

quencies using markers and addition­al detectors assigned to the markers
which are simultaneously displayed

◆ Fully automatic interference measure-

ments in conjunction with external
EMI software packages from
Rohde & Schwarz, including, for in­stance, determination of the worst
case by automatic switchover of the
phase and protective ground settings
via the USER port for remote-con­trolled line impedance stabilization
networks

Test Receiver ¸ESPI 3

Accuracy and reproducibility are also key
parameters for all applications of the
¸ESPI test receiver family.

The combination of test receiver and
spectrum analyzer provides an optimum
concept for precompliance measure­ments in development environments.

Standard-conforming EMI
measurements

Fitted with the optional preselector/pre­amplifier (¸ESPI-B2), all ¸ESPI
models feature an excellent dynamic
range compared with other precompli­ance solutions and are, therefore, able to
perform precise interference measure­ments with pulse repetition frequencies
(PRF) from 10 Hz in line with
CISPR 16-1-1.

¸ESPI-B2: preamplifier and preselection filters up to 3 GHz

The input stages of precompliance test equipment, which often feature
a rather poor overload capability, would be hopelessly overdriven
without a preselection unit. This is different with the ¸ESPI where,
in combination with preselection filter units, a low-noise preamplifier
comes after the filter module but before the mixer stage. It must be
possible to switch the preamplifier on/off as required, since in the case
of high signal levels, the dynamic range would be reduced by an amount
numerically equal to the gain. Where low signal levels are to be
expected, it is best to switch in the preamplifier. Since the Test
Receivers ¸ESPI operate both in the spectrum analyzer mode and in
the test receiver mode, both modes offer the choice of switching the
preamplifier on or off. In the receiver mode, the preselection filter
setting is fixed, whereas in the analyzer mode it can be selected.

Measurements to commercial EMI stan­dards such as CISPR, EN 550xx, ETS, FCC,
ANSI C63.4, VCCI or VDE can be carried
out directly by comparing the EMI spec­trum with the associated limit lines and
switching on the appropriate detectors
(PK, QP, CAV, AV, RMS-AV, RMS).

The detectors

Depending on the operating mode of the
¸ESPI 3 and ¸ESPI 7, i.e. spec­trum analyzer or test receiver, the follow­ing detectors are available:

◆ Analyzer mode: MaxPeak, MinPeak,

AutoPeak, Sample, Quasi-Peak,
Average, CISPR Average, RMS,
RMS Average

◆ Receiver mode: MaxPeak, MinPeak,

Quasi-Peak, Average, CISPR Average,
RMS, RMS Average

Spectrum analyzer mode with selectable preselection filters and preamplifier switched on

Up to 3 detectors can be activated simul­taneously and the results displayed.

The bargraph display, with current detec­tor value and MaxHold display, clearly
shows the results of manual circuit
adjustment when the DUT cabling is
arranged for maximum emissions and
when the antenna is aligned relative to
the DUT for a maximum reading.

In the receiver mode, the QP detector is
coupled with the time constants, pre­scribed by the standard, as a function of
the frequency range. This ensures that
the correct time constants and IF band­width are used for signal weighting in the
CISPR bands. This means much greater
ease of operation for the user.

4 Test Receiver ¸ESPI

The measurement bandwidths

The measurement bandwidths of the
¸ESPI are designed for a large variety
of applications:

The analyzer mode provides all –3 dB
bandwidths from 10 Hz to 10 MHz
(in 1/3/10 sequence). In the receiver
mode, the –6 dB bandwidths can also be
selected by softkey: 200 Hz, 9 kHz,
120 kHz plus 1 MHz bandwidth.

Moreover, approx. 40 digital channel
filters are available.

Like the detectors, the standard-conform­ing CISPR bandwidths can be coupled as
a function of the frequency range. If
necessary, the coupling can be disabled.

The preselector/preamplifier option
(¸ESPI-B2) is available as a protec­tion against overloading by pulsed, high­power signals and for ensuring the valid­ity of signal evaluation in the linear oper­ating range of the measuring instrument.
The advantage of this option is that, in
the analyzer mode, the preselection fil­ters or the preamplifier can be switched
on or off as required.

SCAN table

User-selectable parameters in
up to 10 subranges

The basis for all reproducible measure­ments is a scan table with up to ten sub­ranges and user-programmable fre­quency parameters such as START, STOP,
STEP SIZE, resolution bandwidth, mea­surement time per frequency as well as
RF attenuation setting at a constant value
or coupled to AUTO RANGE overload
monitoring. For sensitive measurements
(if low signal levels are expected), the
preamplifier can be switched on or off as
a function of the subrange.

Test Receiver ¸ESPI 5

Diagram and graphics display can most
easily be defined via ADJUST AXIS.

Marker functions and
split-screen display

In addition to normal FULL SCREEN
display, a second window is opened in
the SPLIT SCREEN mode for bargraph
display with current detector values and
MaxHold display. By activating "Tune to
Marker" the receive frequency and the
amplitude of the detectors coupled to the
marker are displayed as a bargraph and
numerically. This makes things consider­ably easier for the user.

The split-screen display in the analyzer
mode makes it possible to resolve fine
spectrum detail. By coupling the marker
frequency (in screen B) to the center fre­quency of screen A, parameters such as
bandwidth, span, RF attenuation can be
selected separately to detect spurious
which are close to the signal and cannot
be seen in the overview spectrum.

Additional applications –
extra performance

Modern communications systems are
required to achieve optimum spectral
efficiency at high data rates. For the 3rd
generation CDMA mobile radio systems
currently under development, this is
achieved by a number of measures, for
example high-precision power control.

The ¸ESPI is the ideal measurement
tool for diagnostic measurements,
development, precertification and post­certification owing to its excellent RF
characteristics:

◆ Total measurement uncertainty

– Spectrum analyzer mode: 0.5 dB

(without preselection)

– Receiver mode: <1.5 dB

◆ Displayed average noise level of

typ. –155 dBm (1 Hz) without
preamplifier

◆ Phase noise of typ. –145 dBc (1 Hz) at

an offset of 10 MHz providing opti­mum conditions for ACPR mea­surements on WCDMA systems

The resolution bandwidths of up to
100 kHz are fully digital and provide –
in addition to high selectivity – an ideal
basis for accurate (adjacent-)channel
power measurements owing to a
maximum bandwidth deviation of 3 %.

Test Receiver ¸ESPI 7

The

R&S®ESPI comes as standard with a large variety of

functions

Fit for the future

Owing to its modular design, the
¸ESPI is optimally equipped to
handle today’s measurements and the
measurements of the future. The design
already takes into account both hardware
and firmware extensions so that the
¸ESPI will meet all requirements in
the years to come as well. A safe invest­ment for the future.

Ergonomics&design

The ¸ESPI sets the new standard in
the precompliance class. The 21 cm (8.4")
color display makes it easy for the user to
read results and provides an overview of
the parameters which have been
selected.

Vertical and horizontal rows of softkeys
make it easy to perform even complex
measurements. Parameters such as fre­quency and amplitude are entered by
means of dedicated hardkeys and unit
keys.

Wide dynamic range

Featuring the lowest displayed average
noise level in its class (DANL typ.
–145 dBm at 10 Hz RBW), the ¸ESPI
measures even small signals precisely,
when using the optional Preselector/Pre­amplifier ¸ESPI-B2 from 9 kHz to
3 GHz even down to –153 dBm (10 Hz
RBW). Together with the high intercept
point, this yields an intermodulation-free

Displayed

level in receiver
mode with
preselector/
preamplifier
switched on

range of typ. 100 dB – an excellent value
even for higher middle-end instruments.

Phase noise

The ¸ESPI’s minimal phase noise
makes it suitable for demanding mea­surements both close to the carrier
(typ. –113 dBc (1 Hz) at 10 kHz) and far
from the carrier (typ. –125 dBc (1 Hz) at
1 MHz). The ¸ESPI is therefore opti­mally equipped for performing spectral
analysis and ACPR measurements on nar­rowband systems such as IS-136 or PDC
as well as on wideband systems such as
IS-95 or WCDMA.

Spectrum analyzer application,
ACPR measurements

Measurement of the adjacent-channel
power ratio (ACPR), which many mobile
radio standards stipulate for components
and units, is performed in the ¸ESPI
analyzer mode by automatic test routines.
All settings, measurements and filters
required for a selected standard are
activated at a keystroke.

In addition to a large number of prepro­grammed standards, the channel width
and channel spacing can be selected as
required.

Due to its excellent dynamic range, the
lowest phase noise in its class and its
RMS detector, the ¸ESPI sets the
new standard for the upper middle-end –
even for ACPR measurements.

TOI measurement

Test routines for TOI, OBW, etc
are standard

The ¸ESPI offers fast test routines for
a multitude of typical laboratory mea­surements. The routines make postpro­cessing superfluous and supply results
directly:

◆ Determination of TOI

◆ Occupied bandwidth (OBW)

◆ Burst power with peak, average and

RMS indication as well as standard
deviation

◆ Modulation depth of AM signals

◆ Phase noise

◆ Bandwidth marker

Of course, these functions can also be
used via the fast GPIB interface.

Test Receiver ¸ESPI 9

Optional tracking generator
9 kHz to 3 GHz

The optional Internal Tracking Generator
¸FSP-B9 up to 3 GHz and External
Generator Control ¸FSP-B10
enhance the two ¸ESPI test receiver
models to yield scalar network analyzer
functionality. Gain, frequency response,
insertion and return loss are measured
using a selective method with a wide
dynamic range without being affected by
harmonics or spurious from the genera­tor. The Internal Tracking Generator
¸FSP-B9 can be used in both
¸ESPI models and covers the fre­quency range from 9 kHz to 3 GHz. A fre­quency offset of ±150 MHz can be set for
measurements on frequency-converting
modules. The tracking generator can be
broadband-modulated by an external I/Q
baseband signal.

Optional LAN interface

With the aid of the optional LAN Interface
¸ FSP-B16, the ¸ESPI models can
be connected to common networks such
as 100Base T so that functions such as
file logging on network drives or docu­mentation of measurement results via
network printer are available. The
¸ESPI can also be remote-controlled
via the LAN interface. Control is via a soft­panel that behaves exactly as if it were
part of a real instrument. The LAN inter­face has a clear speed advantage over
the IEC/IEEE bus – in particular when
large blocks of data are transmitted.

Easy generation of reports
owing to PC compatibility

◆ PC-compatible screenshots, no

conversion software being required

◆ Windows printer support

◆ LabWindows driver

◆ LabView driver

◆ SCPI-compatible

◆ ¸FSE/ESIB-compatible GPIB

command set

◆ Customized training

10 Test Receiver ¸ESPI

R&S®ESPI-K50 – external trigger for measuring field-strength profiles

To measure the coverage field strength of
a communications or broadcast network,
continuous level measurements have to
be performed at a high measurement rate
and the results must be forwarded to an
evaluation unit.

When a displacement sensor/GPS system
is used, the external trigger input of the
¸ESPI can be used to start the single
measurements. The level values can thus
be accurately assigned to the measure­ment site.

Lab model or robust portable
unit

Whether as a desktop model for the lab,
in a 19" rack, or as a robust unit with edge
protectors and carrying handle for
portable use – the ¸ESPI always
looks good.

The coverage measurement function is
only available in the receive mode and in
the case of remote control. The ¸ESPI
performs the coverage measurement in
two different ways:

◆ All measurements are performed on a

discrete frequency
(sample rate >100 ksample/s)

◆ A channel list with up to 1000 chan-

nels is cyclically processed, i.e. a new
frequency is set for each measure­ment

Additional channel filters

In addition to the channel filters included
as standard in the ¸ESPI, the option
provides filters with bandwidths of

5.6 MHz to 8 MHz for DVB-T signals as
listed below:

◆ 5.6 MHz: ISDB-T (Japan)

◆ 6.0 MHz: ATSC (USA, Korea)

◆ 6.4 MHz

◆ 7.0 MHz: DVB-T (Europe, Australia)

◆ 8.0 MHz: DVB-T (Europe)

Environmental compatibility

◆ Fast and easy disassembly

◆ Small number of materials

◆ Mutual compatibility of materials

◆ Easy identification of substances

through appropriate marking
(plastics)
