NOTE
When monitoring performance, the transmitter controls are always displayed on the left side, the receiver
controls are always displayed on the right, as shown below in Figure 22.
Figure 22: Performance Monitoring Screen. MaxErr Screen
–
Displaying Graph & Data.
The screen appears, displaying receiver (Rx) data. To display transmitter data, tap on a Tx button.
Note the yellow and red horizontal lines in the display. These are performance thresholds:
◼
Yellow
. The link is unstable.
◼
Red
. The link is faulty, with a high probability of errors.
Two types of measurements are tracked by the system:
◼
MaxErr
. The per-channel maximum recorded value of the residual error for PAM-8/16.
The Max Error measurement is the absolute value of the maximum distance between the
input signal on a given channel and the decision threshold in the HDBaseT modulation
detection scheme. This measurement behaves as a peak detector, so the value read is
always the maximal error witnessed on the channel.
◼
MseErr
. The per-channel mean square of the residual error for PAM-8/16.
The actual MSE value is a fractional negative number of db. The higher the absolute value
of the MSE, the better the quality of the HDBaseT signal (i.e. -19.8 is better than -18.3).
To display data, tap on the
MaxErr
or the
MseErr
button on the Transmitter or Receiver side. The
background of the tapped button appears in gray.
