Setting the QAM modulation

Inverting the user signal

In this menu, you can set the QAM modulation and for excep-
tional cases and “older” digital cable receivers invert the
spectral position of the user signal “

inverse

”.

Setting the QAM modulation
• Use

to set the QAM modulation (“

4

” … “

256

”).

—> For higher QAM modulation, the output symbol rate is

lowered. An output QAM modulation of > 64 QAM
places a large burden on the cable network. Due
to noise, delay and frequency response problems,
reception of the converted output signal can be im-
peded.

Inverting the user signal
• Use the

buttons to place the cursor under “

• Use

to set the spectral position to “

inverse

”.

• Press the

button.

vated.
