Information
                                    9	kHz to 30 MHz -30 to +137 dBiaV

Radio-interference (EMI) measurements to CISPR, VDE and FCC
regulations

Interference (EMI) measurements to MIL and VG regulations

Radiomonitoring,

remote frequency measurements

Selective voltage measurements in laboratory and test department

The Test Receiver ESH 3 demodulates and measures AM
double-sideband, single-sideband, PM and FM signals, as well
as sinusoidal and impulsive interference, over the range

9	kHz to 30 MHz. High overload capacity, wide dynamic range,
manifold measuring and evaluation capabilities, and numerous
available accessories make the ESH 3 suitable for selective
voltage and two-port measurements - also in automatic test
systems - and for all applications in the field of
radiomonitoring (page 5) and EMC (electromagnetic
compatibility - EM! measurements - page 4),
Selective voltmeter. Its wide measurement range of -30 to +
137 dB(W permits the use of the Test Receiver ESH 3 as an
automatic high-precision selective voltmeter in the labo-
ratory, test department and service workshop without any
accessory units. For high*impedance test items the Active
Probe ESH 2-Z2 can be supplied. The Clamp-on RF Current
Probe ESH 2-Zt is available for measuring RF current in
electric conductors. Excellent receiver selectivity makes it
possible to measure signals of targe level differences to a
high degree of accuracy even when there are many signals
present. Possible applications: SSB two-tone measurements,
measurement of harmonics, non-harmonic spurious signals and
sideband noise on generators, intermoduiation and
crossmodufatson measurements on RF modules. In all these
applications the ESH 3 can be set either to low-noise or
low-distortion measurement. Automatic linearity testing
permits an inherent non-linearity to be distinguished from
that of the test item.
Other features

•	Synthesizer-based design offers frequency setting.and
readout to crystal accuracy - resolution 100 Hz

•	Automatic frequency scanning with selectable stai.rt and
stop frequencies and step sizes - recording of measured
results on printer and/or XV recorder {VDE/FTZ/Mi.L chart
paper can be used)

•	Accuracy in compliance with CCiR recommendations

•	Automatic calibration of level and frequency offset
measurements; frequency response and bandwidth correction
values are automatically taken into consideration, making
for optimum speed and accuracy of level measurements

•	Automatic measurement of voltage, field strength, current,
pulse spectral density, and two-port attenuation, with
indication of respective physical unit; conversion factors
for probes and test antennas and bandwidth correction values
are automatically taken into consideration

•	Digital data output in p.V to V, dBjiV, dBm and
corresponding units for current field strength, and pulse
spectral density

•	High overload capacity, outstanding overall selectivity,
automatic indication when overdriven; automatic linearity
test triggered at thè push of a key

•	Programmable measuring times of 5 ms to 100 s for
average-vaiue and peak-vaiue indication; determination of RF
input levei variation (MAX./MIN. as in cases where fading
occurs) with programmable measuring times

•	Two*port and remote frequency measurement capability

•	Additional signal evaluation capabilities;
frequency-offset, modulation-depth and frequency deviation

•	Storage of 9 complete device settings and 5 range limits
for automatic frequency scanning; stored contents and last
device setting are preserved when the receiver is switched
off or the current supply is interrupted

•	Remote-controlinterface conforming to IEC 625-1 {IEEE 488}
for universal application; Talk-Only Mode fordata output to
IEC(IEEE)-bus-compatible printer without using a controller

Calibration generator. The calibration generator output
providing SOdBjiV ±0.5dB into 50 Q at receiver centre
frequency is ideally suited for measuring the frequency
response of amplifiers and fillers. The attenuation
measurement range extends to 110 dB and the gain measurement
range to 57 dB. The RF Current Probe ESH 2-Z1 permits easy
measurement of the shielding effectiveness of cables. The
return loss of two-terminal networks (e. g. antennas) and cf
four-terminal networks can be measured with the calibration
generator in conjunction with a VSWR bridge.

In the remote frequency mode it is possible to connect a
frequency counter to the generator output for exact (remote)
frequency measurement of the signal received by use of the
reconversion principle.
Signai evaluation

© Four switchable IF bandwidths: 0.2/0.5/2.4/10 kHz

® Average, peak and puise weighted {CISPR PubL 1 and 3)
indication with programmable measuring times

© Switch-selected demodulation modes A0, A1, A3, A3J (USB,
LSB), F3 - built-in loudspeaker and phones output

© Analog indication of level and frequency offset in
addition to the digital data output

® Indication of RF input overload or overloading of other
essential stages and automatic linearity test at the push of
a key

#	Broadband 75-MHz IF output forconnection of panoramic
adapter or spectrum analyzer

@ Narrowband 30-kHz IF output for connection of oscilloscope

#	AM and FM demodulator outputs

® Recorder outputs for level and frequency offset

S Generator output for signal frequency measurement

@ Digital measurement of modulation depth, frequency offset
and deviation
attenuation curves can be readily output on an XY recorder
(Figs. 1 and 2). The start and stop frequencies and maximum
and minimum levels set on the ESH 3 define the recorder
writing area. The frequency axis can be either linear or
logarithmic. VDE/FTZ/MIL or the user’s own chart paper can
be used.
