Powering on and getting started with SapphireTX
Transmitter
With the primary connections in place as described previously, the SapphireTX Transmitter
is ready to be powered.
The SapphireTX Transmitter can be powered on by connecting a battery to the battery pate
(Anton Bauer or VLock) or by powering through the DC input on the base.
After approximately 45 seconds the front panel will move from its ‘Initialising’ screen to the
‘Status’ Menu.
For successful transmission the following key parameters must be correctly set to match the
video source and to match the RF parameters to the receiver. Incorrect setting of these
parameters may result in errors in the encoder stream or possibly no stream at all.
The key parameters can be set in the Configuration Menu (See Front panel Menu Structures
for more details).
Key Parameters
Mode 1: 4K Ultra HD Mode
VIDEO FORMAT: The Video Format must match the video source eg. 2160p50 or 2160p59
SAMPLE FORMAT: The Sample Format must match the video source eg. SQD (Square
Division) or 2SI (two sample Interleave)
FREQUENCY: The frequency must match the frequency set at the receiver
RF OUTPUT: Must be set to ON
RF POWER: Must be sufficient to transmit to the receiver typically this is set to 100mW
MODULATION: Must be set to match the receiver typically this is set to DVBT
BANDWIDTH: Must be set to match the receiver typically this is set to 8MHz
CONSTELLATION and FEC: Must be set to match the receiver and also to give sufficient
bitrate for the video being encoded, for UHD this might be 64QAM FEC1/2
PIDS: All the PIDs (video, Audio, PRC and PMT) should match between the SapphireTX
Transmitter and decoder. The decoder does have an auto service mode to simplify this
process.
Mode 2: HD Quad Mode
