The **SVB-4W0-R/E** is a professional-grade, high-performance **video splitter and extender** typically used in industrial, security, or professional AV environments. It is designed to take a single video source and distribute it to multiple outputs while maintaining signal integrity over distance. Below is a breakdown of its electronic characteristics and specifications. ### 1. Core Functional Specifications The device acts as a distribution amplifier, ensuring that the signal strength does not degrade as it is split into four separate channels. | Feature | Description | | :--- | :--- | | **Input Channels** | 1 Channel (Primary source) | | **Output Channels** | 4 Channels (Distributed outputs) | | **Interface Type** | Typically BNC or VGA (Common in SVB series) | | **Signal Type** | Analog Video (Composite) or High-Resolution VGA | | **Power Supply** | DC 12V / 500mA (Standard) | --- ### 2. Key Electronic Components & Features The internal circuitry of the SVB-4W0-R/E is engineered for stability and long-term operation. * **Amplification Circuitry:** Unlike passive splitters that weaken the signal, this unit uses active transistors/ICs to boost the signal to 1Vp-p, ensuring the image remains bright and sharp on all four screens. * **Impedance Matching:** The device uses precision resistors to maintain a standard **75-ohm impedance**. This prevents signal reflection and "ghosting" effects on the display. * **ESD Protection:** Most industrial units in this category include Electrostatic Discharge (ESD) protection diodes to prevent damage from power surges or static buildup during cable plugging. * **Bandwidth Management:** It supports high bandwidth (typically up to 10MHz or higher depending on the specific sub-model), which is critical for maintaining resolution in high-definition analog signals. --- ### 3. Application Use Cases Because of its "R/E" (Rack-mountable/Enhanced) designation, it is often found in the following setups: 1. **CCTV Surveillance:** Distributing a single camera feed to four different DVRs or monitoring stations. 2. **Public Information Displays:** Sending a PC output to four different monitors in a lobby or terminal. 3. **Production Studios:** Feeding a master video signal to multiple preview monitors. --- ### 4.
