o Manual operation or automatic

screen and report of results on print
er or plotter
* Operation from AC supply or battery
Test Receivers ESN and ESVN are
used to measure and demodulate both
(DSB, SSB,
pulse) and frequency-modulated sig-
amplitude-modulated
nals as well as narrowband and
broadband interference in the range
from 20 to 1000 MHz (ESVN 20/30),
9 kHz to 2050 MHz (ESN) and 9 kHz
to 2750 MHz (ESVN 40).
Their high overload capability, wide
dynamic range, high measurement rate
and versatile evaluation capability
make the test receivers ideal tools for
e all applications in the fields of ra-
diomonitoring and radio network

vant standards

measurements in manual and auto-
matic operation

Manual operation
The test receivers perform the measure-
ments at a fixed frequency with the de-
sired bandwidth, attenuation, meas-
urement time and mode of indication.
The following measurements are car-
ried out simultaneously:
* level measurement
e modulation and deviation measure-
ment
e frequency and frequency-offset
measurement
Thanks to the simultaneous measure-
ments, the parameters of the receive
signal can be determined in a single
test cycle. The level is indicated both
on a digital LC display and an analog
meter. This is ideal for alignments or
for the determination of maximum sig-
nal strength, eg for manual direction
finding of transmitters or interference
sources. The results of modulation and
frequency measurements are digitally
displayed on the screen.
IF analysis |
While measurements are taking
place, IF analysis allows the spectrum
to be examined about the receive fre-
quency. Measurement of level, modu-
lation and frequency, and signal as-
sessment using the built-in loudspeaker
are made at the center frequency of
the extended spectrum. The following
settings are available for the frequen-
cy spectrum analyzed via the receive
channel:
— span: 10 kHz to 10 MHz
— resolution bandwidth: 1/3/10 kHz
— level display range: 80 dB
— sweep time: 50 ms to 20 s
Two test waveforms can be displayed
simultaneously on the screen. The dis-
play mode for the two curves can be
selected independently from one an-
other to suit the task:
— Max Hold: to locate pulse-shaped or
brief signals
— Max/Min: to locate CW signals, eg
in TV channels (the CW signal
stands out in the min curve)
— Average: to suppress broadband
signals and thus highlight narrow-
band signals
These display modes allow fast identi-
fication and measurement of useful
and interference signals in a signal
spectrum. Marker functions are provid-
ed for the rapid evaluation and meas-
urement of the signals identified in the
receive channel:
— Marker — Peak: The maximum level
of the spectrum is determined.
— Marker — Center: fast measurement
of the desired signal in the receive
channel
The integrated TV demodulator allows TV program identification via an external TV monitor
Automatic operation
RF analysis
The receive frequency range is
scanned and the result displayed as a
spectrum on the screen. Free selection
of the measurement parameters such
as start frequency, stop frequency, IF
bandwidth, measurement time, attenu-
ation, indication mode is possible. Sin-
gle or recurrent scanning can be se-
lected. It is possible to display two test
curves simultaneously. For comparison
measurements waveforms can also be
loaded from a floppy.
Three different modes are available
for frequency scanning:
Overview: Scanning over the desired
frequency range is at a maximum
speed and with fixed attenuation. It is
quasi-continuous and at a high sweep
rate so that all signals are covered.
Scan: Scanning is quasi-continuous,
the step size and measurement time
being selectable. Thanks to automatic
attenuation setting, an extremely wide
dynamic range is available at full
measurement accuracy. Up to five sub-
scans with free selection of the test pa-
rameters can be joined to ensure opti-
mum setting for each subscan.
Channel: The receivers perform a scan
over a defined frequency data set with
up to 400 different frequency values.
The channel mode is ideal for radio-
monitoring. The measurement can be
triggered at a specific frequency by an
adjustable threshold with defined
dwell time which in turn switches a
carrier-operated relay (COR). The re-
sults (level, modulation, frequency off-
set) can be output automatically to-
gether with the time of the day as lists
on a printer. Thus it is possible to use
the ESN or ESVN alone without an ex-
ternal computer for unattended radio-
monitoring over long periods of time.
4 Test Receivers ESN/ESVN
Thanks to the builtin preselection fil-
ters, a high overload capability, band-
widths to CISPR16 and VDE 0876 and
quasi-peak and average value weight-
ing to standard from 150 kHz on, the
receivers can be used for the fields of
civil RFI measurements in addition to
radiomonitoring and high-precision
useful-signal measurements. Nonvola-
tile storage of 22 limit lines with up to
50 values is possible, two of them can
be displayed on the screen at any giv-
en time.
The results can be made available in
graphical form or as lists via a plotter
or printer or stored on a floppy with
the associated complete receiver set-
up. Any relevant information can be
added to the test report either by en-
tering it via a line editor or, more con-
veniently, via an external keyboard.
Parameters stored in the receiver such
as date, time and receiver settings are
automatically recorded. Results load-
ed from a Hoppy will be processed,
compared with a measurement or
documented in the same way as
measured values.
Radiomonitoring
The test receivers are able to perform
all important radiomonitoring and
measurement tasks in manual, semi-au-
tomatic and fully automatic operation:
o Field-strength measurements to
CCIR Rec. 378-4 with R&S test an-
tennas and direct display of the
results
From shortwaves to microwaves: ESN or ESVN together with an appropriate
antenna is upgraded to a fully automatic radiomonitoring system without the
use of an external controller
* Frequency and frequency-offset
measurements with internal or ex-
ternal precision reference
e Modulation depth, frequency devi-
ation and phase deviation mea
surements
* Visual spectrum monitoring with RF
and IF analysis
e |F analysis with aural check of the
received signal using AM, FM and
SSB demodulators with selectable
AF bandwidthds and AF squelch or
using a TV monitor for indentifying
TV signals
Use in computer-controlled
systems
Full use of the high measurement rate
of the test receivers is possible only in
the remote mode using a high-speed
controller. In the determination of field-
strength profiles, the test receivers are
able to furnish 5000 measured values
per second after being triggered by a
positioning system or a time base.
3000 measured values with a dynam-
ic range of up to 100 dB are available
when the special autorange function is
used.
The field strength can be determined at
different frequencies within a particular
frequency band at a rate of 2.5 ms per
measured value. With cellular networks
it is thus possible to measure for in-
stance the field strength of several base
stations according to Lee's statistical
method using a single receiver at the
normal speed of the test vehicle.
For radiomonitoring, up to 10,000 fre-
quencies can be stored in the receivers
and combined to give a maximum of
100 segments. A set of 20 different re-
ceiver setups at the most can be as-
signed to each segment. The modula-
tion limit values can be defined sepa-
rately for each segment. The measure-
ment results (level, modulation, frequen-
cy) are output to the controller either by
blocks, continuously or depending on a
limitvalue violation automatically de-
tected by the receiver (alert mode). Au-
tomatic user-port control with program-
mable wait time allows even complex
test sequences involving several anten-
nas to be carried out.
Interfaces
For further signal analysis and for driv-
ing or feeding add-on units, the test re-
ceivers have the following interfaces:
* Coding and supply socket (AN-
TENNA CODE) for active antennas
and other accessories
e 10.7-MHz IF output, switchable be-
tween regulated and unregulated IF

tion finder (external access to the

nal) output for connection to a TV
monitor, switchable between posi-
five and negative video polarity,

cess to the internal LO
* AM/FM output for the demodulated
(DC-coupled} AF for evaluation of
an audio signal on an oscilloscope

ulation, eg for connection to A/D
converters and further processing

nal computer

Design
The service-friendly modular design of
ESN and ESVN and the strict compli-
ance with EMC rules ensure excellent
specifications regarding RFI emission
and immunity.
Comprehensive selftest functions allow
troubleshooting down to the function-
al-block level signalling to the user the
impaired function. Thus the faulty mod-
ule can easily be found and replaced
with a minimum of effort and without
affecting the other modules.
