The HVIT0x0B ASI, 3G, HD, and SD SDI Isolator is a transformer based solution that provides reduction and elimination of hum and noise. This noise can interfere with digital video transmission. It is caused by the difference in ground potential, especially those above 20 volts, or induced currents in long cable runs.
This common mode noise results in the degradation of the bit timing of high speed digital signals. This leads to bit errors. These bit errors will reduce the quality of the video and data content within the transmission signal. Digital signals do not degrade gracefully as they often suffer from a cliff effect. This will cause the digital signal to be lost altogether.
However, the singular most common symptoms of hum in digital signals is intermittent horizontal black streaks. These streaks are often one line in thickness.
The SDI Isolator can also provide crucial ground protection. This occurs when ground or earth potential differences exist between equipment. These potential differences often result in permanent damage to video equipment. This damage can be costly and take a crucial video signal off-air. Both 1kV and 4kV isolation voltages are available. The 4kV unit is ideal for non broadcast applications such as industrial, medical, oil and gas.
The HVIT0x0B SDI Isolator comes in a compact standalone unit. For a rack mountable version that is fitted with an XLR plate, see the HVIT0x0R.
