Description
ASI and 3G/HD/SD SDI Isolator
The HVIT SDI isolators are critical components for implementing ground isolation, protection and noise reduction. The SDI isolator is usable as an ASI isolator, or a 3G-SDI, HD-SDI, SD-SDI isolator.
Highlights:
- Eliminate noise and hum from digital video signals
- Protect Equipment from ground voltages
- Standard isolation better than 1kV and extended isolation up to 4kV
- Supports all 3G, HD, SD SDI formats
- Compatible with ASI video signals
- Passive device
- High performance and wide bandwidth design
- Ultra-compact and lightweight
- Standalone unit and rack mountable versions
Description:
The HVIT0x0 range of Isolation transformers is a transformer based solution providing the reduction and elimination of hum and noise caused by differences in ground potential, especially those above 20 volts, or induced currents in long cable runs. As a result, these ground problems manifest themselves as signal noise on the digital video transmission.
Hence, the resultant common mode noise causes degradation of the bit timing of the high speed digital signal leading to bit errors. a consequence of the bit errors is a reduction of 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 causing the 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.
Installing an isolation transformer is crucial in implementing ground protection. This occurs when ground or earth potential differences are in existence between equipment. As a result, permanent damage to video equipment is often the consequence. Damage of this nature is not only costly but, crucially, could also take a video signal off-air.
The isolator is usable as an ASI isolator or a 3G-SDI, HD-SDI, SD-SDI isolator.
Both 1kV and 4kV isolation voltages are available and the 4kV unit is ideal for non-broadcast applications such as industrial, medical, oil and gas.
The HVIT0xo range of Isolators is available in two compact packages, a standalone unit and rack mounting unit. The rack mounting version has a standard XLR mounting profile allowing it to be mounted on to a XLR rack mounting plate.
