Output Configuration
The IF output settings include:
The output can be set as active or mute.
When muted there is no modulator output.
The output frequency is selectable between
57 & 145 MHz (SMD910). Set to 70 MHz to
feed the SMD 920 L-Band upconverter.
The level for the IF output is adjustable
between -30 to -5 dBm
. The SMD 920’s
optimum input level default is -10 dBm.
The tilt adjustment allows a user to adjust the
overall slope of the output spectrum. The
range is selectable from -3 to +3 dB
If the RF L-Band SMD 920 option is installed in the
SMD 989 bay, the ability to configure the RF output is
shown.
The output can be set to active or mute.
When muted there is no modulator output
.
The output frequency is settable at an L-band
frequency of 950 to 2150 MHz if the LO
Offset is set to 0 MHz.
To enter a satellite frequency, first enter the
Satellite Frequency followed by the entry of
the block upconverter frequency
– press
Enter. If the difference is not in the L-band
The Modulator Configuration menu contains an
output configuration selection. When selected it leads
to settings for the IF output and RF output. This
section overviews the IF Output and RF Output
menus.
