ESD
simulation
The simulation of
electrostatic discharges is
an important part of EMC
tests for all types of
electronic equipment. Many
test standards require pulse
voltages of a few kV to 15kV
while the automotive
industry has even higher
requirements (voltages of up
to 30kV must be applied to
determine the immunity
level). TESEQ’s ESD
simulators are characterized by a compact
and user-friendly design. The NSG 435 and
NSG 438 both feature a large, easy to read
LCD display that shows the user all
necessary parameters during tests. They can
be operated either from rechargeable
batteries or from a mains power supply.
Product highlights
- Air and contact discharge
operation 200V to 30kV
- Touch screen display
- Battery-powered
- Compliant with industry
standards (IEC, ANSI, SAE, ISO,
etc.)
- Interchangeable network modules
- Adjustable discharge detection
- ISO self-test function
Comprehensive immunity
testing
Transient pulses
superimposed on power
and data cables, power
interruptions, and
Electromagnetic fields
often cause malfunctions
in electronic circuits.
Immunity testing can
ensure that components,
instruments, and systems
function properly during
routine operation in
conformance with product
standards. TESEQ offers
an extensive range of
pulsed immunity
generators as well as
coupling networks,
antennas, variable
transformers, and
accessories to ensure
that interference
phenomena can be safely
and reliably reproduced.
TESEQ’s new NSG Series
Immunity Generators and
EMC Suite test software
simplifies testing
procedures and test file
processing, deliver
flexible and adaptable
test reports, and offer
remote operation.

RF Amplifiers
for EMC testing
Teseq has a
complete range
of broadband RF
Amplifiers
suitable for EMC
test loads.
EMC RF immunity
testing is a
harsh
environment. RF
Amplifiers are
often operated
at their limits
and into poor
VSWR match. All
RF Amplifiers in
the Teseq range
are solid state,
Class A
configured and
therefore
mismatch
tolerant. Teseq
RF Amplifiers
can withstand
all of their
power being
reflected back
into their
output without
any risk of
damage.
Low harmonic
levels are also
an important
specification
during RF
immunity
testing. Teseq
RF Amplifiers
offer harmonic
levels >20dBc
below the
fundamental,
making them
suitable for the
EMC test
environment.
Teseq RF
Amplifiers are
available in the
following
frequency bands.
- 10kHz – 100MHz
- 100kHz – 1GHz
- 150kHz – 230MHz
- 1MHz – 400MHz
- 10MHz – 1GHz
- 80MHz – 1GHz
- 800MHz – 3.1GHz
- 2GHz – 6Ghz
Various power
levels are
available for
each RF Power
Amplifier
frequency band
to ensure the
desired field
strength is
achieved when
combined with
the customers
EMC test
configuration.
Power levels of
up to 1kW are
available.
With many years
of experience in
design,
manufacture and
supply of
broadband RF
Power Amplifiers
to the EMC
market
worldwide, Teseq
is sure of the
long term
performance and
reliability of
their product.
So confident in
fact, that Teseq
are now offering
a 3 year
warranty on all
new purchases of
RF Amplifiers.
EMC antennas
achieve better
results faster
TESEQ provides
an extensive
range of EMC
antennas. The
well-known BiLog®
antenna, the
first ultra wide
band EMC
emission
measurement
antenna,
represents an
important
milestone in the
development of
EMC measuring
instruments. The
BiLog® is a
unique
combination of a
sophisticated
matching network
and innovative
design that
provides
significant
advantages over
conventional EMC
antennas. As a
result,
measurements can
be performed in
one pass without
changing the
antenna,
resulting in a
potential test
time savings of
up to 30%.
Subsequent
measurements are
also easier to
conduct and more
reliable. With
its X-Wing® antennas, TESEQ has applied the
advancements of the BiLog® antenna to
immunity testing. The advantage of running a
complete immunity test with a single antenna
provides significant time savings. TESEQ
also offers loop antennas, biconical
antennas and broadband horn antennas.
