1. INTRODUCTION

The MONTEST-HD4K Signal Generator & Analyzer is an advanced and handy

tool for generating, testing and verifying the signal path within your 6G
HDMI ecosystem. With 88 built-in resolutions, 55 test patterns and over

a dozen types of A/V analysis functions, this unit provides an enormous

range of testing options. HDMI data packet, EDID and HDCP analysis
is supported along with EDID upload and emulation. Additionally the
Status and Control Data Channel (SCDC) can be monitored, allowing
HDMI 6G signal detection and analysis. Up to 8 channels of LPCM
audio test tones can be generated with a wide range of frequencies.

The unit also supports the ability to upload up to 2 user-generated

graphic les which can be used as additional test patterns. The use of

multi-function and multi-color backlit buttons allows for easy operation
of the unit’s wide variety of functions and a clear OLED display
provides a way to quickly view the current signal status information. In
addition to the front panel buttons, the unit can also be controlled via
RS-232, Telnet and IR providing a complete range of control options.
