DGA 9552 N is a bidirectional attenuator, i.e. the attenuation and power capability specification is valid for both directions.

There is a large variety of applications for this attenuator: The measuring range of a spectrum analyzer can be increased. Any kind of meter can be protected against overload; it can be used to control the linearity of a meter reading. It can minimize measurement uncertainty caused by mismatched impedances. During an EMI receiver calibration, an attenuator directly at the pulse generator output is inevitable.

Gtemcell offers an innovative shielding product made of a highly conductive double layer of aluminum with internal reinforcing mesh in polyester for the coating and creation of shielded environments within pre-existing structures.  The application frequencies range from a few Mega Hertz to several GHz with an electric field attenuation of 45-80dB. The great advantage is ease of application even on curved and complex surfaces and lower costs which make this application particularly attractive. GTEMCELL supplies the shielded fabric or performs all the environmental shielding work. The aesthetic finishes are the responsibility of the customer.
The construction includes a preliminary inspection to evaluate all the "critical" aspects such as the openings present: doors. windows, air conditioning systems, electrical connections and consequently draw up an economic evaluation of the costs.

VRC (Reverberation tent chamber)

This product is a chamber made of a flexible metal fabric tent assembled as a cavity that provides a periodic electromagnetic environment that is randomly polarized, spatially uniform, and isotropic.

The walls of the chamber are inducted in mechanical vibration between 5 and 20Hz, able to reflect the electromagnetic waves inside the tent with a reverberation effect. VRC finds applications to create an electromagnetic environment for immunity and emission testing. The reverberation tent chamber offers the advantage of higher field-to-input power ratios and faster test throughput times than other test methods.

The IEC 61000-4-21:2003  is a comprehensive standard for performing electromagnetic testing with a reverberation chamber.

The modular construction of the tent fabric allows customized dimensions assembly to meet space limitations e/o including the device under test.  The VRC is supplied complete with a technical panel and optional filters.

Linear polarized Stacked Logarithmic Periodic Broadband Antenna with N- or 7/16connector for Receive and Transmit Applications. Main Application: Generation of defined field strength levels for radiated immunity testing. Further the cross-polar rejection of the STLP 9128 F is excellent.

The optoUART system can be used for the optical transmission of UART-signals up to a data rate of 1 Mbit/s.

It can be used to transmit UART-signals over long distances or to handle ground potential problems. With the optical transmission and the shielded case, the system is well equipped for EMI and EME tests.

ptoTTL 5-3-u is used for the optical transmission of TTL (Transistor-Transistor Logic) 3.5 & 5 V TTL signals digital signals. Up to 16 digital signals with a sampling rate of 40 MS/s (each channel) can be transmitted. The system consists of a transmitter supplied by batteries, a simplex-62,5/125µm-multimode optical cable, and a receiver – which has integrated batteries as well.
