Receive settings
You need to specify the receive frequency and enable the RF ports that will receive input from
downconverters. You should also check the other receive settings and, if necessary, apply a gain boost for
selected downconverters if the RF reception is poor.
From the main menu, select
Receive
and configure as follows.

Setting
Description
Receive Frequency
Sets the receive frequency assigned for your event.
Update Remote Tx
Parameters
When selected, keeps the receive and transmit frequency at the same
value. If you change the receive frequency, the remote transmitter
frequency automatically changes to the same value.
It is recommended that you link these parameters, but during diagnostic
testing you might want to not change the transmitter frequency but change
the receive frequency setting to look at another camera.
Receive Input Enable
Enables input streams for live RF ports in Slot A and Slot B with a
downconverter attached. It is recommended that you select all RF ports.
Note that enabled input streams are fed to the diversity switch, which
connects the downconverter antennas to the receiver. Disabled inputs are
tuned but ignored.
Receive BNC Power
Enables power to selected BNC connectors in Slot A (RF1
–4) and Slot B
(RF5
–8). It is recommended that you turn off BNC power to unused ports.
Downconverters connected directly by coax cable require power (DC
power over coax), downconverters connected through the Real Freedom
fiber system do not.
BNC power is required to be enabled if the Real Freedom Active UHF
Splitter is attached as the Real Freedom fiber alone is protected against
DC power.
Note that an electrical short or overcurrent automatically disables power
on selected BNCs.
Receive Gain Boost
Activates high gain mode for selected downconverters in Slot A and Slot
B.
Select the check boxes to apply a receive gain boost of 20 dB. You
may wish to do this for extra long cable runs where signal loss is
anticipated or where the RF reception level is poor.
page to determine whether you need to
enable receive boost.
LO Frequency
Only required when using third-party downconverters.
Defines the Local Oscillator (LO) frequency used to convert the transmit
frequency down to the frequency range required by the receiver. The
required value is usually marked on the downconverter.
Note that if you are using Real Freedom downconverters, the required
frequency is automatically populated and cannot be changed.
Receive Band
Specifies the frequency range for signal reception. Choose the band that
encompasses the receive frequency for the downconverters.
If you change the receive band, the receive frequency will change if the
value that you have set is out of the selected band.
Modulation Scheme
Defines the modulation scheme.
The default value is ‘DVB-T’, a European
digital video broadcasting standard.
In
‘BSI control’ mode, the selected scheme syncs with the transmitter.
