HDBaseT Link Quality Test
The HDBaseT Link Quality Test will check the HDBaseT link is stable over a sustained period of time There are two
drop down menus, the first is the output you are testing, the second is the type of test you are doing.
The Mean Square Error test is the ratio (in dB) of the signal power in relation to the originally transmitted signal
vs the received and it is an analogue measurement. This reading is directly affected by kinks, termination & other
cable issues Each Channel has a colour that represents the same colour in the twisted pair in the Cat cable All
four of these Channels should each be below the -15dB line Otherwise, the cable quality will be marked as “Poor”
Also, all four of these Channels should be within 3dB’s of each other, for example, -21dB -20dB -21dB & -19dB
Otherwise, the cable quality will be marked as “Poor”
The Channel Errors test is a measurement of the number of digital errors on the channel, such as packet loss
and bit errors Each Channel has a colour that represents the same colour as the twisted pair in the Cat cable
All four of these Channels should be below the 40-line Otherwise, the cable quality will be marked as “Poor”
Also, all four of these Channels should be within 3 of each other, for example, 35 36 35 34 Otherwise, the cable
quality will be marked as “Poor”
It is also possible to check the link quality remotely by logging into your installer account at monitoringpulse-

Note: If any of the above criteria is broken at any time but it then recovers to normal, this can still indicate an issue
in the cabling so the matrix will remember this information and will continue to mark the cable as “Poor”. This can
explain if your cables look to meet the MSE test criteria but are still marked as “Poor” then it is likely to be caused by
a momentary “bad spike” (reading below MSE criteria) happening in the past.
