Battery voltage variation and noise simulation generator

Radiated immunity test system

The ITS 6006 consists of an integrated RF signal generator, a RF switch and EUT monitoring interfaces. The unit is designed for various radiated EMC applications in the 80MHz to 6 GHz frequency range. In addition to the generator, the system includes the AM and PM modulators necessary for EMC testing. Other modulators can be connected to the external modulation input of the ITS 6006. The RF signal can be switched to one of four outputs, where up to four power amplifiers can be connected directly. Additional
RF switches are available for combining two amplifier paths into a single antenna connection.
Two of these relays are included for the four amplifier paths.

Product highlights

Multifunction immunity testing system

The NSG 4070 is TESEQ’s next-generation multifunctional immunity test system. It replaces the NSG 2070 and offers expanded functionality while adding new features. The NSG 4070 has a broader frequency range of 9kHz to 1GHz and a modular design which accommodates both internal and external amplifiers. The system can be used in a wide variety of applications, including tests according to IEC/EN 61000-4-6 and various BCI applications. The NSG 4070’s signal generator and power meter can also be used to implement test systems for other applications such as IEC/EN 61000-4-3, IEC/EN 61000-4-20, and IEC/EN 61000-4-21.


Powerful and easy-to-use firmware allows the NSG 4070 to be operated independently. However, it can also be controlled by an external PC and control software. The USB port in the front panel can be used with a standard USB memory stick to download test and measurement data for documentation purposes.

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.

• Emission testing
• Immunity testing
• Wide frequency range
• Individually calibrated
• Optional accredited calibration

GTEM and TEM cells

TESEQ provides GTEM/TEM test cells for EMC emission and immunity testing in a shielded environment in accordance with IEC/EN 61000-4-3 and IEC/EN61000-4-20. Pre-certification tests can be conducted during development in compliance with IEC/EN 55022, VDE0871, and other standards. TESEQ's GTEM/TEM cells generate largely homogeneous and simple to calculate fields with an excellent VSWR over the entire frequency range.

• High field strengths at low amplifier output
• No need to measure reflected power
• Only simple single-channel power meters required
• Reduced test time
• Customized configurations
• Frequency range DC to 20GHz

Compact reverberation chambers

Reverberation chambers (RCs) are modern EMC test environments in addition to the established methods like semi- or full anechoic rooms (SAR/FAR), open area test sites (OATS) or (G)TEM cells. They can be used for emission, immunity and shielding effectiveness testing.
A reverberation chamber basically consists of a shielded room and a stirrer
which changes (“stirs”) the electromagnetic field inside the chamber. The chamber itself behaves like a multi mode resonator. The main benefit of RCs is the low input power requirement for generation of high field strengths.
Teseq offers two new types of reverberation chamber models. The chamber XS, with the size of 2.7 x 1.5 x 1.3, has a starting frequency of approx. 500 MHz and chamber 2XS, with the size of 1.5 x 0.8 x 1.0 m, starts from approx.
800 MHz.
Chambers XS and 2XS are equipped with an optimized stirrer and a special stirrer motor to achieve the maximum performance.
