1. Introduction
The AVerMedia 4K HDMI Signal Detector CT130 is designed to check and report DC
voltage level of each HDMI signal pin and quickly tests the continuity of all HDMI
features.
This tester connects a source and a display to verify whether all digital signals are
being transmitted properly, and it also ensures that the source HDMI signals are
compliant with the specifications.
Two modes are used to check the signals, first mode is TMDS signal only with
automatic detection, second mode is all the HDMI signals and sending voltage values
to a dedicated PC program.
2. Package Contents
1. 4K HDMI Signal Detector CT130
2. USB Cable
3. Features
1. Support HDMI 2.0b display up to 4Kp60.
2. Low power consumption

7. Introduction of Modes
The CT130 is an HDMI-signal-measuring and HDMI-signal-validating toolkit. To
measure the TMDS differential signals, the CT130 integrates a signal switch that can
direct the TMDS signal to either an output port (path 1) or a MCU (path 2).
Figure 7-1 TMDS switch
The CT130 provides two modes for HDMI output signal validation:
1. MODE 1 - Auto Test Mode:
In Auto Test Mode, the TMDS path is switched to path 2 (MCU) for
measurement, then the CT130 detects whether an HDMI cable is plugged in or
not. After an HDMI cable is plugged in, the CT130 starts to measure the DC
voltages of HDMI signals (TMDS, power 5V). If all signals pass the validation,
the TMDS switch changes to path 1 and the LED indicator turns blue.
Otherwise, the TMDS path remains at path 2.
2. MODE 2 - PC-Operating Mode:
In PC-Operating Mode, users can send a command to measure specific HDMI
signal and then receive the measurement result or even perform an HDMI “hot
plug action”via USB connection from a host PC.
