Note
Some configuration options are dependent on each other. In this case,
selectable values are highlighted in white, non-selectable values in
gray.

Fill level
The data rate of the sender may vary depending on the image contents and on the transmission quality. To ensure an undisturbed
reception, a reserve must absolutely be observed.
We recommend you to set the maximal fill level to 95%.
If the current fill level exceeds the maximal fill level, it may cause image disturbances, e.g. mosaic images.
If the net data rate of the signal exceeds the net data rate of the output channel, the modulator overflows. This overflow leads to
disturbances. If the modulator overflows, the status LED on the front side of the device lights in red.
Filtering the programmes reduces the net data rate of the input signal. Subsequently, the net data rate of the output signal is also
reduced. The data rate depends furthermore on:
•
channel bandwidth (7 or 8 MHz)
•
error correction rate (FEC)
•
modulation rate
•
guard interval
•
transmission mode
Device Redundancy
If a device is used as a
backup device
for another device, it will indicate that the modulators are disabled and no levels will be
displayed.
