11.4.1
Modulation On/Off
The Modulation on/off parameter sets the modulation mode of operation.
NOTE:
The Modulation on/off setting through the front panel is parallel supported using the [F2] shortcut key
on the touch-pad.
The available options are:
■
Off
– Modulation is disabled. Shortcut combination is
F2 + Down
.
■
On
– Modulation is enabled. Shortcut combination is
F2 + Left
.
The Modulation on/off default value is
On
.
Front Panel
To set the Modulation on/off parameter on the front panel:
❖
Navigate
Root > IF
or
L-Band Modulation > Modulation on/off
.
Web Manager
To set the Modulation on/off parameter in the Web Manager:
❖
