These Open TEM-cells are well suited for immunity testing of small objects according to European (CE) and automotive standards (SAE J1113-25) or for biological experiments. The advantage of these OTEM cells is that they are open and it is very easy to control the functions of the EUT (Equipment Under Test). The applications are for instance the immunity testing of watches, pagers, telephones or PCB’s.
Transverse ElectroMagnetic (TEM) cell or Crawford cell (named after its inventor) is used to generate accurate electromagnetic waves over a wide frequency range: DC (0 Hz) to GHz. EM waves generated in the cell propagate in transverse mode and have the same characteristics as a plane wave. It can be used to calibrate E-field broadband probes for testing radiated E-field immunity as well as for measuring radiated emission from a product with a spectrum analyzer/EMI receiver.
Double Transverse ElectroMagnetic (DTEM) cell or Double Crawford cell (named after its inventor) is used to generate accurate electromagnetic waves over a wide frequency range: DC (0 Hz) to 4 GHz and measure attenuation through materials in a very predictable and accurate way. EM waves generated in the cell propagate in transverse mode and have the same characteristics as a plane wave. It can be used to calibrate E-field broadband probes for testing radiated E-field immunity as well as for measuring radiated emission from a product with a spectrum analyzer/EMI receiver.
Linear polarized Logarithmic Periodic Broadband Antenna combined with a 4:1 Broadband Dipole (Aluminium tubing) for Receive and Transmit Applications.
The VARISTOR-TESTER PG 6-250 is a compact test generator for testing the surge current capability of varistors. The unit contains a combination wave generator and a surge voltage generator acc. to CCITT, ITU-T.
The high-voltage impulse generator PG 6-364 generates standard impulse voltages with waveforms 1.2/50 µs and 10/700 µs. The Output voltage is adjustable between 0.2 kV and 6 kV. The polarity of the output voltage is selectable. Positive, negative or alternating polarity of the output voltage can be preselected. The generator is designed for dielectric testing of components and systems as well as testing of the electromagnetic compatibility of electronic systems and devices acc. to CCITT K17/K20/K22, ITU-T/K44, IEC 61000-4-5, VDE 0847.
The Combination Wave Generator PG 10-504 is a combined impulse-current-/impulse-voltage generator which, for high-impedance loads, RL > 100?, delivers a standard impulse voltage with waveform 1.2/50µs and, for short-circuited output, a standard impulse current with waveform 8/20µs. The generator allows surge testing of components and devices, the galvanic coupling of surges to cable shields, shielded enclosures and cabinets as well as testing electromagnetic compatibility, EMC, of electronic devices and systems against pulsed and conducted interference.
The Combination Wave Generator PG 12-804 is a combined impulse-current-/impulse-voltage generator which, for high-impedance loads, RL > 100?, delivers a standard impulse voltage with waveform 1.2/50µs and, for short-circuited output, a standard impulse current with waveform 8/20µs. The generator allows surge testing of components and devices, galvanic coupling of surges to cable shields, shielded enclosures and cabinets as well as testing electromagnetic compatibility, EMC, of electronic devices and systems against pulsed and conducted interference.
The Surge Test Generator PG 24-2500 is a combined impulse current-/impulse-voltage generator which, for high-impedance loads, RL > 100?, delivers a standard impulse voltage with waveform 1.2/50µs and, for short-circuited output, a standard impulse current with waveform 8/20µs, as defined by IEC 60. The peak value of the pulse output voltage can be adjusted from 0.5 kV to 24 kV. The peak short circuit current amplitude is 12 kA.
The front-chopped-wave generator IPG 506 is used for measuring dc spark-over voltage and impulse spark-over voltage of over-voltage protectors according to CCITT / ITU-T, K12. DC spark-over voltage: A linearly rising voltage, rate of rise 100 V/s up to 640 V, simultaneous plus and minus, is connected to the device under test. The spark-over voltage of these two simultaneous impulses is measured and shown in the display. Impulse spark-over voltage: A linearly rising impulse voltage, simultaneous plus, and minus, rate of rise 100 V/µs up to 5000 V/µs, open loop amplitude 5000 V, is connected to the device under test. The spark-over voltage is measured by use of a peak detector. The results of these two simultaneous impulses are shown on the display. The picture is shown with PA 503 Option.
