Atlona Technologies AT-3GSDI500 3G/HD/SD-SDI Pattern Generator is an advanced SDI pattern generator with multi-format (3G/HD/SD) and multi-pattern support. Besides still and moving video test patterns, other features such as audio (SMPTE-291M) are also provided. The AT-3GSDI500 can support up to 8 channel AES compliant audio with 48KHz sample rate. Another attractive feature of AT-3GSDI500 comes from bypassing the HDMI input and allowing users more testing patterns for connected displays, or treats the AT-3GSDI500 as an advanced HDMI to SDI converter with 3G capability. With portable size, the AT-3GSDI500 is equipped with four buttons and a LCM screen to ease the control. This device provides a cost effective way to calibrate and test SDI enabled video devices and displays.
