Brief description
Miniport Receiver EB200 with Active
Directional Antenna HE200 is a portable unit for radiomonitoring in the
wide frequency range from 10 kHz to
3 GHz. Whether used for monitoring
In case of power supply interruption,
all the data is stored. Operation can
thus be resumed immediately after the
power supply is restored.
• Location of close-range to medium-
range targets with the aid of Handheld Directional Antenna HE200
• Detection of undesired emissions
including pulsed emissions
• Detection of unlicensed transmitters
communicating illegally or interfering with licensed transmission
emissions, detecting interference or
locating mini-transmitters irrespective
of their position, EB200 offers features
unrivalled in its class. The favourably
priced and compact receiver with LAN
interface may also be used in computer-based stationary systems.
The EB200 is characterized by high
input sensitivity and frequency setting
accuracy throughout the frequency
range from 10 kHz to 3 GHz.
Its small dimensions and low weight as
well as a sturdy, pickup-proof die-cast
aluminium housing with well-protected
integrated operating elements make
the EB200 ideal for use in places
which cannot be reached with a vehicle. Its low power consumption permits
battery operation typically of four
hours. The EB200 battery pack is easily accessible and can be exchanged
quickly.
EB200 fulfils the following tasks:
• Monitoring of given frequencies,
eg storage of 1 to 1000 frequencies, squelch setting, constant monitoring of one frequency or cyclical
scanning of several frequencies
• Searching in a frequency range
with freely selectable start and stop
frequency and step widths of
1 kHz to 9.999 MHz

• Protection against tapping by detecting miniature spy transmitters
(bugs)
• Monitoring of one's own radio exercises in a service band
• Monitoring of selected transmissions
• Remote-controlled operation via
modem and PC in coverage measurement and monitoring systems

Digital IF section
The EB200 covers the wide frequency
range from 10 kHz to 3 GHz. Processing all signals available with optimum
signal-to-noise ratio requires a large
number of IF bandwidths. This problem cannot be solved by means of
analog filters as space is limited. The
solution is a digital IF section in which
a wide variety of different filters can
be implemented in a relatively small
space with the aid of DSP. The EB200
has 12 IF bandwidths between
150 Hz and 150 kHz. The following
digital demodulators are available:
AM, FM, LSB, USB and CW. If the
receiver is fitted with the IF panorama
option, the number of bandwidths is
increased to 15 up to 1 MHz. Bandwidths over 150 kHz are for level and
deviation measurement as demodulation is not possible.
Scanning modes
Frequency scanning
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 may be included in the
data set:
• Step width
• Signal threshold (dBµV)
• Dwell time (s)
• Hold time (s)
• Signal-controlled continuation
• Suppression (individual frequen-
cies or search ranges)
a scanning run. The content of any memory location can be transferred to
the receiver manually
using the RCL key, by turning the setting knob or
automatically by activat-

ing the memory scanning
process.
Frequency spectrum
Fitted with the frequency
spectrum (DIGI-Scan)
option, EB200 scans the
frequency range of interest
... listen mode ...
with digital control and displays the associated spectrum. Emissions detected
can be seen at a glance.
Aural monitoring of the
information is possible by
simply pressing a softkey.
EB200 then goes to the
... differential mode
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 made with the distance, 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 case of spreadspectrum transmission.
Memory scanning
The EB200 uses 1000 definable memory locations. A complete data set,
such as frequency, mode of demodulation, bandwidth, squelch level, etc,
can be assigned to each memory location. The memory content can be
edited or overwritten with the results of

Overview
IF panorama
Level (zoomed)
Function
The EB200 is a superhet receiver with
a third intermediate frequency of
10.7 MHz. In spite of its compact
size, it was possible to implement an
advanced receiver concept. The
receiver input is equipped with a highpass/lowpass combination or tracking preselection, as required, to
reduce the signal sum load. Intermodulation suppression equals that of
many receivers used in stationary
applications.
The low degree of oscillator reradiation is a result of large-scale filtering. A
modern synthesizer concept featuring
very low phase noise permits switching times of less than 3 ms. Effective
frequency and memory scanning is
thus possible.
For every task
the optimized view ...
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 guarantee
extremely low spurious as well as high
interference rejection.
BITE
The receiver is permanently monitored
by built-in test equipment. If deviations
from the nominal are detected, an
error message is output with a code
informing on the type of fault.
Serviceability
Modern design and the use of plug-in
modules guarantee short repair times.
All the modules may be exchanged
without any recalibration or adjustments being required.
Remote control
All the receiver functions can be
remote-controlled via the serial
RS232C interface of a controller. For
measurement tasks, the LAN option
provides a hundred times faster speed
as well as easy connection and control
of multiple receivers from a PC. With
these different versions the user can
select the type of remote control to suit
his tasks.
Operation
The operational concept of the EB200
meets all the requirements of a modern
radiomonitoring receiver, ie all the
essential functions, such as modes of
demodulation, bandwidths, etc, can
be set via labelled keys directly.
Settings that are not used during current operation are available in submenus. The hierarchy of menu control
is implemented according to priorities
for ease of use.

Handheld Directional Antennas
Uses
The handy and highly broadband
Active Directional Antenna HE200 in
conjunction with portable receivers
(eg EB200) is ideal for locating transmitting and interfering sources. The

direction is found by pointing the
antenna towards the direction of maximum signal voltage. The overall frequency range from 0.01 MHz to
3000 MHz is covered by 4 exchangeable broadband antenna modules
each with a distinct directional pattern. A low-noise broadband amplifier
may be added to increase sensitivity
in the active mode. The amplifier is
bypassed in the passive mode and in
this case the antenna may also be
used in the vicinity of strong transmitters.
• Unambiguous direction finding*),
ie directional pattern with the receive maximum pointing to the
front in the frequency range
20 MHz to 3 GHz
• The maximum of the antenna output signal serves as a direction
criterion (maximum direction
finding)
• Handy size despite very wide
broadband characteristic
• Weight is kept to a minimum due
to material used and antenna
design
• Can be used for vertically and
horizontally polarized signals in
the frequency range 20 MHz to
3GHz
• Wide dynamic range due to
switchable passive and active
mode
*) For the unambiguous determination of the angle
of incidence of a signal, at least two different
sites are required. The transmitter is to be located
at the intersection point of the DF beams.

200 MHz bis 500 MHz
Description
A broadband cardioid directional pattern is obtained in the frequency
ranges 20 MHz to 200 MHz and
200 MHz to 500 MHz by using a
loaded loop antenna in two different
sizes. A log-periodic dipole antenna
covers the range 500 MHz to
3000 MHz with a directional pattern.
A loop antenna is available as an
option for the lower frequency range
of 0.01 MHz to 20 MHz.
The four RF modules can be
exchanged by means of a quickrelease catch provided at the supply
and display unit. The supply and display unit comprises the following modules:
• Antenna electronics made up of
low-noise amplifier as well as active/passive switchover circuit
• Active/passive switchover by
means of relay
The low-noise amplifier is bypassed in
passive mode and has no supply voltage. Passive mode is thus also possible without batteries and external voltage supply. The antenna should only
be switched to active mode if there are
no strong transmitters in close vicinity
and if the sensitivity of the receiving
system (antenna with receiver) in the
passive mode is not sufficient to detect
the signal. When the amplifier is activated, a yellow LED on the rear of the
supply and display unit indicates
whether the supply voltage from battery or external source has fallen
below the permissible range.
