Traditional "Humbucker" and Isolation Transformer approaches to interference are not applicable to SDI signals. Mains hum is well below the SDI signal frequency spectrum and (unlike analogue video) the SDI signal is not sensitive to near-DC attenuation. However, the problems of signal distortion and operator shocks caused by a voltage difference between two pieces of equipment connected by a SDI signal feed still exist.
These LEN Ground Isolators use a broadband highpass filter to provide DC electrical isolation between the two pieces of equipment, whilst permitting the full bandwidth of the SD-SDI, HD-SDI or 3G signal to pass. This method outperforms all other broadband transformers for SDI signals currently available.
Also known as the SDI DC Isolation Highpass Filter, they are non-inverting and suitable for ASI format.
