RECEIVER AND AN ANALYSER FUNCTION
4. Testing Digital Audio on an display or A/V Receiver
An audible test beep is available and can be set via the Tone menu.
The PCM Sine Wave facility allows users to set up the audio resolution and assign bits per sam-
ple (e.g. 16bits/24bits etc), sample rate (e.g. 44.1Khz/ 96Khz etc), level as well as the desired au-
dio channel (e.g. L, C, R, RL, RC. RR. SW etc).
The AT4K has is able to generate a sine wave to offer installers the means to ensure audio signal
is correctly transmitted via the HDMI connection tested.
To activate the test tone please follow the steps listed below
Please connect the HDMI input of the DUT to the HDMI OUT on the AT4K

HDCP TESTER
Set as receiver the AT4K can verify HDCP of video player (e.g 4K disc player/4K set top box) as well as
other DUT (Device Under Test).
The AT4K provides three options HDCP 1.4 / HDCP 2.2 / no HDCP for users to select from and confirm the
HDCP authentication of DUT.
1. As HDCP Receiver
Set as transmitter the AT4K can transmit HDCP encrypted video. It also provides three modes
HDCP 1.4 / HDCP 2.2 / no HDCP (both shown under HDCP-2.2-0) to select from.
Upon completion of initial tests user is able to repeat HDCP encrypted video. To do so users need
to select the Auto-Restart button.
HDCP test Procedure:
1. Connect the AT4K HDMI output port to HDMI input port on the display.
2. Select HDCP Test from the Sink Test Menu.
3. Touch Enable HDCP 1.4 or Enable HDCP 2.2 buttons on the 4.3” touch screen display of the
AT4K.
If and when a test-pattern is generated the choice of HDCP will indicate if the display is fully com-
patible, if the HDCP assigned is not supported by the screen the screen will loose connection with
the AT4K and the test pattern disappear.
2. As HDCP Transmitter

HDCP TESTER (Cont.)
Set as transmitter the AT4K can transmit HDCP encrypted video. It also provides three modes
HDCP 1.4 / HDCP 2.2-0/ HDCP 2.2-1 to select from.
Upon completion of initial tests user is able to repeat HDCP encrypted video. To do so users need
to select the Auto-Restart button.
HDCP test Procedure:
1. Connect the AT4K HDMI output port to HDMI input port on the display.
2. Select HDCP Test from the Sink Test Menu.
3. Touch Enable HDCP 1.4 or Enable HDCP 2.2 buttons on the 4.3” touch screen display of the
AT4K.
If and when a test-pattern is generated the choice of HDCP will indicate if the display is fully com-
patible, if the HDCP assigned is not supported by the screen, the screen will loose connection with
the AT4K and the test pattern disappear.

EDID ANALYSER
The AT4K offers the most convenient way for users to analyse EDID accuracy and stability. You can verify,
view and acquire the EDID of an HDMI device through its connections and links (e.g. Tx/Rx settings etc)
EDID Analysis Procedure:
▪ Connect the output port of chosen device to the AT4K HDMI output.
▪ Select EDID Analyse from the Sink Test Menu.
▪ Touch the Read button to get the EDID information of DUT.
EDID acquisition Procedure from Rx/Sink:
▪ Connect the output port of chosen device to the AT4K HDMI output.
▪ Select EDID Analyse from the Sink Test Menu.
▪ Touch the Learn from RX button on 4.3” screen to acquire the EDID. The EDID will be saved in the
AT4K’s input port

P14
LOOP TEST
The AT4K offers the unique estimator for evaluating the quality of cables or chosen devise. Users
can simply connect the cable or DUT (Device Under Test) to the AT4K to form a loop, it will exam-
ine the HDMI bitstream pixel by pixel. The measurement statistics will be displayed on the AT4K’s
screen and offer useful information for secure a stable and accurate transmission chain.
Procedure of Loop Test:
▪ Please note: The Loop Test only support 1080p@60, 4K 30Hz and 4K 60Hz resolutions
▪ Connect the AT4K and the DUT or cables.
▪ Select Loop Test from the Loop Test Menu.
▪ Set the Test Time. A minimum of 5 seconds is recommended for all tests, and touch the
START button on the AT4K’s touch screen. The AT4K will capture the signal from its transmitter
through the loop and evaluate the transmission quality.
Evaluation criteria:
Tx
Rx
Test Result Definition
Pass The value of Bit Error Rate is less than 1
Fail The Bit Error Rate is more than 1
Please ensure that when an active cable is tested the correct end of the cable is assigned
to the input and output of the AT4K. In cases where the connection is reversed the AT4K
will not be able to generate a reading.
