Electromagnet

Strong magnetic fields in a precisely defined test gap.

Generate magnetic fields from DC to approximately 1 MHz for experimental applications. The AGEM 5521-23 combines a 23-turn coil, a split toroidal ferromagnetic core and a built-in monitor loop in a compact aluminum housing.

Balanced VHF-LISN

A balanced RF termination for reproducible mains-cable conditions.

The VHFB 8801 provides a defined RF termination for the EUT AC mains cable during radiated-disturbance measurements. It offers balanced live and neutral impedances and is described as an alternative to a CMAD in CISPR 16-1-4, Edition 5 test configurations.

Unbalanced VHF-LISN

A controlled, unbalanced RF termination for the EUT mains cable.

The VHFU 8802 provides unequal terminal impedances during radiated-disturbance measurements of AC-mains-powered equipment. This defined imbalance creates controlled differential-mode to common-mode conversion and offers a VHF-LISN alternative to a common-mode absorption device (CMAD).

Frequency-specific compensation for the AGEM 5521-23

The Schwarzbeck NFCN 9732-x nF reduces the series impedance of the AGEM 5521-23 electromagnet at a customer-selected frequency up to 1 MHz, enabling high coil currents with generator voltages below 20 V RMS under compensated operating conditions.

Specify your working frequency when ordering. Connection cables are optional.

Capacitive EFT/burst injection for signal and data cables.

The Haefely IP4B couples electrical fast transient and burst pulses onto cables connected to peripheral equipment for IEC/EN 61000-4-4 testing. Its 1 m active coupling length accommodates cable diameters from 4 to 40 mm according to the V2026.06 datasheet. Coupling is capacitive, so the injected disturbance depends on the cable and its placement..

Diode Pulse Limiter with built-in 10 dB high power attenuator and fuse lamp to protect sensitive measuring equipment when measuring spectra with high energy. Thanks to the built-in fuse lamp, serious overload situations of sensitive equipment can be recognized fast and reliably. A replacement bulb is placed inside the unit. The pulse limiter prevents expensive equipment defects. The very flat frequency response allows high measurement accuracy, even if only a few sample values are used for correction.

The Multiple Control Device NCD is suited for the operation of optionally up to 8 devices with multiple axis of motion. Those devices can be any combinations of antenna masts, turntables, cable guide rails or any other positioning equipment.  

This controller NCD permits the operation in manual, semi-automatic and remote-control mode via IEEE 488.2 (GPIB bus), or optionally other interfaces, of multiple devices simultaneously.
