Military and civil monitoring from 9 kHz to 3 GHz
ITU-compliant measurements
The Monitoring Receiver R&S ESMB is
ideally suited for military monitoring tasks
and spectrum monitoring in line with ITU
recommendations as well as for use in
radio investigation services.
The range of applications includes:
◆ Signal detection
◆ Signal search in frequency and
memory scan mode
◆ Spectrum occupancy measurement
◆ RF and IF analysis
◆ Coverage measurements (option)
◆ Field-strength measurements
General
The R&S ESMB is a monitoring and test
receiver for all radio detection and
radiomonitoring
tasks in line with ITU-R,
and for radio investigation services. The
compact and sturdy design combined
with low weight makes the R&S ESMB a
versatile and universal unit for stationary
and mobile use.
Applications
The following measurements in line with
ITU-R specifications can be performed by
the R&S ESMB:
◆ Frequency and frequency offset to
ITU-R SM 377
◆ Field strength to ITU-R SM 378
◆ Modulation to ITU-R SM 328
◆ Spectrum occupancy and identifica-
tion with external PC to ITU-R SM 182
◆ Bandwidth to ITU-R SM 328
The optimized features of the R&S ESMB
allow fast performance of the following
additional tasks in military radiomonitoring and radio investigation services:
◆ Frequency scan with predefined
frequency ranges
◆ Memory scan of up to 1000 memory
channels
◆ RF frequency spectrum (option)
◆ Audio monitoring of CW, AM, SSB
and FM transmissions
◆ Identification
Description
As a ½ 19" unit, the R&S ESMB is ideal
both for mobile use and for rackmounting. It contains the following
functional units:
◆ A/D and DSP module with digital IF
filters, digital demodulators for CW,
AM, LSB, USB, PULSE, FM, PM, IQ
and ISB, parameter measurements
and FFT processing of IF panoramic
display
◆ Band and tracking preselection
◆ RF frontends for converting the
antenna signal into an IF of 10.7 MHz
◆ Fast synthesizer
◆ Processor system
◆ Display and control unit
◆ Remote control interface
◆ DC/DC converter
Digital IF section
The R&S ESMB covers a frequency range
from 9 kHz to 3 GHz. A large number of IF
bandwidths is required to process the various signals with optimum signal-to-noise
ratio. Maximum quality in a minimum of
space can only be ensured by using ultramodern digital signal processing throughout.
The R&S ESMB is equipped with 18 IF
filters from 150 Hz to 300 kHz, and up to
1 MHz in the IF panoramic mode.

Operation
The Monitoring Receiver R&S ESMB
features full remote control capability as
well as manual control via the front panel.
The operating concept meets all the
demands made on a state-of-the-art
spectrum monitoring receiver, i.e. all the
main functions such as type of modulation, bandwidth, etc can easily be set
directly via labelled keys.
Menu control is organized in priority
levels so that signal processing is not
interrupted by menu changes and the
user has an optimized view of current
operations.
In conjunction with the
Digital Direction Finder
R&S DDF190, the
Monitoring Receiver
R&S ESMB forms a
monitoring system with
excellent price/performance ratio
◆ Step width
◆ Signal threshold (dBµV)
◆ Dwell time
◆ Hold time
◆ Number of scans
◆ Signal-controlled continuation
◆ Suppression (individual frequencies
or search ranges)
Memory scan
The R&S ESMB uses 1000 definable
memory locations. A complete data set
such as frequency, mode of demodulation, bandw
idth, squelch level, etc can be
assigned to each memory location. The
content of any memory location can be
transferred to the receiver manually using
the RCL key.
Emissions detected can be seen at a
glance. Aural monitoring of the information is possible by simply pressing a softkey. The R&S ESMB then goes to the DIGI
Scan listen mode. The stored spectrum is
displayed in the background, and the
emission of interest can be selected and
monitored by marking it with the
frequency cursor.
Location of miniature transmitters at
close range is possible in the differential
mode of the DIGI Scan option. In this
mode, the displayed spectrum is stored as
a reference. Current spectra are superimposed on the reference spectrum, and
any new signals or variations in signal
strength are clearly discernible as peaks.
If the measurement is carried out while
walking across the room, the field
strength of transmitters at close range
varies to a greater extent than that of
transmitters located far away. This differential display ensures fast and reliable location of miniature transmitters even in the
case of spread-spectrum transmission.

Frequency scan
It is possible to define a frequency range
to which a complete data set can be allocated. In addition to receiver settings, the
following scan parameters are included in
the data set:
Frequency spectrum
Fitted with the frequency spectrum
option DIGI Scan, the R&S ESMB scans
the frequency range of interest with
digital control and displays the associated spectrum.

Interfaces
For system applications, the receiver is
equipped with a number of important
interfaces:
device functions as well as data output, but
also transmission of the digital AF. With the
aid of the DIGI Scan option, data for 20 000
channels/s can be output in the scan mode.
Modulation measurement
When equipped with the R&S EB200CM
option, the R&S ESMB can also be used
for coverage measurements. In this configuration, it is possible to perform up to
2000 triggered level measurements on
one frequency or up to 200 multichannel
measurements (with any frequency hopping). This option is only available via the
remote-control interface.
The R&S ESMB together with the R&S
ROMES software form a coverage
measurement system with excellent
price/performance ratio.

Designed to meet the standards
State-of-the-art design
The receiver is designed for both mobile
and stationary operation. Careful screening and filters in all the input and output
lines ensure extremely low spurious emissions and high interference rejection.
BITE
The receiver is permanently monitored by
built-in test equipment (BITE). If deviations from the nominal specifications are
detected, an error message is output with
a code indicating the type of error.
Serviceability
Modern design and the use of plug-in
modules ensure short repair times. All the
modules can be replaced without any
recalibration or adjustments being
required.

Use in computer-controlled
systems
Full use of the performance features of
the receiver can be made in the remotecontrol mode via LAN using a suitable
PC and the Spectrum Monitoring
Software R&S ARGUS or R&S RAMON.
R&S RAMON, which is primarily used in
military and security applications,
enables fast frequency detection and
transfer to support monitoring receivers
(concentration on interactive operation
and signal identification).
R&S ARGUS is intended for applications
focusing on measurements, and is therefore particularly suitable for frequency
management tasks.
For basic tasks, the R&S ARGUS MON
software is available for remote control of
the R&S ESMB. The functionality of this
software, which features a favourable
price/performance ratio, is optimally tailored to the capabilities of the R&S ESMB.
It allows remote control of all settings,
measurement and scan functions as well
as saving of mea
quency, level, offset,
sured data such as fre-
date and time. The
basic R&S ARGUS MON software can be
Scan with 3D waterfall diagram
upgraded to R&S ARGUS for use in more
complex systems. The pictures above
show how easy-to-use and user-friendly
R&S ARGUS MON is. The R&S ESMB
together with R&S ARGUS MON is a costefficient basic system that fulfills all the
ITU recommendations.
