The DVIT175P Digital Video Isolating Patch Panel for ASI, 6G, 3G, HD, and SD-SDI 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 Digital Video Isolating Patch Panel 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 DVIT175P Digital Video Isolating Patch Panel comes in a compact 19″ 1RU rack mounting unit. These units have BNC connectors as standard, other connector types are available, contact us for more details.
