Two Channel RF L-band Switcher

——     YUK-SW02-L     ——

    Overview                                                                                                                                                                                 

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.

    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.
