INTRODUCTION
The MT-305A 3G/HD/SD-SDI to HDMI & Audio Scaler Converter with 3.5” LCD Monitor & local
loopout is an advanced SDI monitor with multi-format and multi-pattern support. Not only receiving SDI
signal, MT-305A can also bypass SDI input to SDI output. It is equipped three buttons and 3.5” panel to
ease the control. With 3.5” panel, the output signal can be monitored and controlled through OSD, such
as the resolution and image adjustment. This device can also be used as a tool for scanning eye diagram
to check the quality of input SDI cable. In addition, it provides a variety of test patterns, which can be
used as a simple SDI pattern generator. MT-305A provides a cost effective way to monitor video devices
and displays.
