6. Press and release the B key to analyze the number of pixel errors detected per color
component of the received HDMI/DVI signal on the LCD (see example below).
R: G: B:
0 21
To stop the analysis, press and release the B key again. The light on the key
extinguishes and the analysis stops.
7. Press and release the ACS key to analyze pixel error rate (in errors per billion) and
number of pixels measured (in billions) in the received HDMI/DVI signal on the LCD
(see example below).
Note: When the number of pixel errors becomes very large, the text "Very high" is
displayed in the bottom row of the LCD (replacing the numbers).
PER: pels/billion
4.255 0.88
To stop the analysis, press and release the ACS key again. The light on the key
extinguishes and the analysis stops.
8. Press and release the DCS key to view the expected and measured values for the first
pixel error detected from the received HDMI/DVI signal (see example below).
original: 40018C
1st error: FFFFFF
To stop the analysis, press and release the DCS key again. The light on the key
extinguishes and the analysis stops.
9. To test the cable at a different frequency, return to step 4.
You can verify the analyzer's ability to correctly analyze pseudo-random noise.
The procedures below provide instructions for testing the accuracy of the analyzer through
the front panel. Note that you can also perform these procedures through the command
line. For procedures using the command line refer to
To verify the analyzer's pseudo-random noise analysis capability:
1. Connect the HDMI/DVI Tx connector to an HDMI/DVI display.
2. Using the Format knob, select an appropriate format for the connected HDMI/DVI
display.
