value of L-band transmit frequency is within 950’000 – 1’750’000 kHz. If LO value is set as
zero (by default) all transmit frequencies in profiles should be set in L-band frequencies.

IMPORTANT! FREQUENCIES SETTING PRINCIPLE SHOULD BE THE SAME FOR ALL NETWORK ROUTERS – EITHER ACTUAL
OR ZERO LO VALUE SHOULD BE SPECIFIED
Power Receive
Turns on LNB power 18 VDC on the demodulators (see max current in the specification);
Power Transmit
Turns on BUC power 24 VDC on the modulator (see max current in the specification);
10 MHz
Turns on 10 MHz signal on modulator or TDMA demodulator;
SpInv
Spectrum inversion on RX or TX ports;
Frequency adjust
Manual frequency adjustment (used to compensate minor frequency shifts);
Carrier search bw
Defines a search range (+/- around the central frequency) in which the carrier is searched by
the demodulators. Broader range slows down the search; narrower range can result in
impossibility to achieve carrier lock.
Identification
Not used in this configuration
Once Site Setup is configured it should be applied to take effect.
2.3 Profiles
Profile is a pre-configured group of UHP settings that defines the mode of operation and the general RF
configuration. This manual describes only one configuration supported by UHP operation mode: SCPC modem.
UHP router may have multiple profiles with various modes of operations or/and different RF settings.
Command menu “Profile” displays all the configured profiles and allows modifying it or creating a new one (see
Figure 9).
