Recently, the new Murideo 8K Seven-G field HDMI generator was entered into DPL Labs’ Certification Program. Almost identical in looks to the previous 4K 6G, this new 8K SEVEN (7G) model is now housed in a complete metal case with much more weight and a rugged design. It has all the necessary goodies to solve just about any system failure and is compatible with 8K and 10K.
While field service technicians have a wide assortment of tools to complete and troubleshoot all kinds of installations, home entertainment has become more challenging over the years. As we all moved into the digital space, the typical tools used for video troubleshooting have long gone extinct.
Back in the day, one could use the display as a test tool to determine problems such as bandwidth, noise, signal levels, and even sound to a certain extent. But not with digital video.
Sometimes intermittent and other times sparkles can appear on the screen, which does not give us enough data to sink our teeth into. Now with the increase to 8K and 10K resolution devices, it requires very sophisticated equipment to do any type of troubleshooting.
The on-screen menu has been improved since the 4K 6G with better hotkeys to HDCP without having to search in the menu. The menu is easier to use with better pull-downs, upgraded built-in screen, and of course all the calibration tools to address any display system.
As before, troubleshooting is easy by just running the generator at whatever resolution you need to test for and positioning the device at the input side. By simple top-down logic, the user can move the generator downstream to each device in the chain providing a step-by-step system analysis. Let’s look at some of the most important numbers.
Both TMDS and FRL digital modulation schemes are provided with a seamless and stable output. The generator can switch digital rates instantly with few to no hiccups. Eye Patterns are robust with near-perfect symmetry.
The most impressive is the notorious DDC channel that tends to haunt each troubled system. Its sharp 92ns rise times and dynamic voltage thresholds can identify some of the weakest interface problems that can be found in the field.
The onset of more fiber installations can put a heavy demand on the system’s 5-volt bus voltage. The need for accurate power management is mandatory with circuitry that can hold and maintain the necessary current in line with the spec for active devices.
The new Murideo 7G has a solid power supply that can hold to the HDMI voltage level and still maintain a 4.8 voltage. This allows integrators to see and understand how their systems are holding up from voltage demands on the bus — important due to the huge amount of AOC cables used for long-distance applications.
On the downside, it would have been nice if the device had a way to display the voltage on the bus while in test. This would indicate high current consumptions and voltage variations that can also raise havoc with any AOC device. However, this can be calculated by process of elimination if the user is well-versed with some DC (direct current) background.
Overall, the Murideo 7G received high scores in both performance and ergonomic design. It uses a power supply brick and DC connector to charge the on-board batteries or if the unit is used for bench work. Nice job, Murideo, for sure DPL Labs has a home for this new 8K generator.
