L-Band RF Video Switcher

上市日期: 2019-07-01

YUK-SW02-L 1U rack-mounted L-band RF switch is an RF  switching system suitable for satellite signal transmission systems. This device supports automatic and manual switching. In the automatic switching mode, the switching level threshold of each channel can be set individually. In the manual switching mode, channel switching can be forced, and the level switching threshold of the working channel can be set. After reaching the switching threshold, it can automatically switch to another channel or force no switching.

YUK-SW02-L equipment support unified network management and point-to-point remote control (point-to-point remote control needs to purchase a remote control terminal separately).

This device has a complete horizontal and vertical power supply function.

Product Feature

❖ Working RF frequency: 950MHz~2750MHz.

❖ RF input level has a wide operating range.

❖ Horizontal polarization H/vertical polarization V switching.

❖ LNB tuner power supply on/off control.

❖ Low power consumption design, low heat, high stability, meet the requirements of environmental protection.

❖ Automatic switching and manual switching function, forced manual switching function.

❖ The front panel has a test port for RF output -20dB.

❖ With buzzer alarm and monitoring parameters and report to the network management system.

❖ Intelligent design, configuration parameters can be set locally/remotely, and can be connected to the system network management or point-to-point remote control.

❖ The display screen actively displays the current working channel and the level value of each channel.



Transmitter Introduction

❖ The RF input port of the YUK1000L-T L-band optical transmitter can provide operating voltage to the Ku-band or C-band downconverter (satellite tuner LNB) connected outdoors through the panel control, and can complete the conversion of horizontal and vertical polarization received by satellite by this device.

❖ YUK1000L-T L-band optical transmitter can be set to automatic or manual working mode. In the automatic working mode, the gain of the whole machine can be automatically adjusted according to the input signal level, so that the laser excitation level always works within the optimal range. Manual working mode allows users to customize the laser excitation level (non-professional users please use the automatic working mode directly).

❖ The front panel of YUK1000L-T L-band optical transmitter provides an input signal monitoring port (main signal -20dB)

❖ YUK1000L-T L-band optical transmitter can provide one loop-out signal interface (optional).

❖ YUK1000L-T L-band optical transmitter has a complete RJ45 network interface, which can be connected to the network management through SNMP or TCP/IP protocol (optional).

❖ YUK1000L-T L-band optical transmitter is equipped with high-quality power supply, and optional dual power supply to improve system reliability.

❖ YUK1000L-T L-band optical transmitter has 10MHz signal transmission version (optional).


Operation Mode


Depending on the actual application, the user can choose from several working modes. These modes can be divided into automatic switching control or manual switching control.


Auto Switch Mode

In the automatic switching mode, the switching level threshold of each channel can be set independently. The main and auxiliary channels can be set, and it can be set to allow or not allow the main channel to automatically switch back to the main channel after the signal is restored.

 

Manual Switch Mode

In manual mode, the working channel can be manually set according to user’s needs, and can be forced to switch to another channel.

Mode settings are stored in the module's non-volatile memory. When powered up, the module will revert to the operating mode settings it was in before the last power outage. When the power is turned off, the A channel of the device can transmit signals normally, but other functions are unavailable.

 

Fast Switching Function

The device has a fast switching function. Press and hold the corresponding button for 3 seconds to perform a fast channel switching function.
