SY 9223-439 – Broadband Transformer 1:2

Frequency range (nominal): 30 kHz - 1 MHz

The SY 9223-439 transformer causes a voltage transformation Uin / Uout = 1 / 2 and is designed for operation with hand-held field coil – e.g. FESP 5132 when performing tests according to IEC 61000-4-39. For this purpose, the field…

SY 9223-7637-4-100 W Balun 9 kHz to 50 MHz

SY 9223-7637-4 – 100 W Balun acc. to ISO-7637-4

Frequency range (nominal): 9 kHz - 50 MHz

The SY 9223-7637-4 is a balanced-to-unbalanced transformer (abbr. balun) – transforming an unsymmetrical RF signal into a symmetrical one while not transforming the impedance. A bidirectional direction of operation is possible. The SY 9223-7637-4 has a low insertion loss, a…

SY9223-100 - Broadband Balun 50 Ω to 100 Ω

SY 9223-100 – Broadband Balun 50 Ohm to 100 Ohm

Frequency range (nominal): 9 kHz - 60 MHz

The balun transforms an unsymmetrical signal at a 50 Ω source impedance into a galvanically isolated symmetrical signal at 100 Ω impedance in a wide frequency range. Thus measurements on symmetrical quadripoles which have an impedance of 100 Ω can…

SY 9223-120B - Broadband Balun 50 Ω to 120 Ω

SY 9223-120B – Broadband Balun 50 Ohm to 120 Ohm

Frequency range (nominal): 9 kHz - 60 MHz

The balun transforms an unsymmetrical signal at a 50 Ω source impedance into a galvanically isolated symmetrical signal at 120 Ω impedance in a wide frequency range. Thus measurements on symmetrical quadripoles which have an impedance of 120 Ω can…

SY 9501 Balun

SY 9501 – acc. to EN 55015 (CISPR 15)

The balanced to unbalanced transformer SY 9501 is designed according to the standard EN 55015 (CISPR 15). This balun is used to measure the attenuation of luminaires (lighting equipment) up to 1.605 MHz. Luminaire attenuation measurements require a 50 Ω…

Broadband isolation transformer SY 9223-17

SY 9223-17 – Broadband Isolation Transformers

Frequency range (nominal): 1 kHz – 300 kHz

Filters for power supply lines are measured according to CISPR 17, annex C (respectively DIN EN 55017, annex C). Two wideband transformers are required to transform the typical impedance of measurement devices from 50 Ω to 0.1 Ω or from…

Broadband balun SY 9223-120

SY 9223-120 – Broadband Matching Balun 50 Ohm to 120 Ohm

Useable Frequency range: 10 MHz - 900 MHz

The SY9223-120 is a balun including a resistive adaption part. It transforms an asymmetrical 50 Ω signal (N-connector) into a symmetrical 120 Ω environment (screw terminals). This balun can be used for transmission measurements according to IEC 61643-21. It is…
