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.

Table 1. Receive settings
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.

Refer to the Receive Status 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.

Dual Pedestal

Specifies whether you want to use a double-capacity wireless link.

‘Single Stream’ creates a single video link with double capacity.

‘Dual Stream’ creates two independent video streams.

In ‘BSI control’ mode, the selected setting syncs with the transmitter.

Bandwidth

Defines the bandwidth of the RF transmission.

In ‘BSI control’ mode, the selected value updates the camera back transmitter. If the bandwidth is not correct, the system will still work if under ‘BSI control’, but if not, you will need to match the value to the transmit parameters.

ASI Input

Defines which rear panel RF inputs are diversified with the rear panel ASI input.

This is always RF1–8, unless you have selected ‘Dual Stream’ mode, where you can select which set of RF inputs are diversified with the ASI input.
