2.3 The WiNRADiO ETC kit (WR-ETC-100)
The ‘WiNRADiO ETC kit’ (hereafter referred to as the 'ETC Kit') provides coherent
synchronization capability between multiple WR-G35DDCi receivers operating in ETC mode.
A single ETC kit is needed for each WR-G35DDCi receiver. In other words, the number of
required ETC kits is equal to the number of coherent receivers.
The ETC kit converts coherent synchronization signals from the Digital synchronization
connector of the WR-G35DDCi (described in Section 2.1 and shown in the Picture 2-2) into
signals carried over standard 50 ohm coaxial SMA cables. This enables the receivers to be
installed while distributed in different PCs. The ETC Kit consists of the following components
(shown in Picture 2-15):
1. The Extended topology configuration board (ETC board)
2. Digital synchronization cable for the ETC board
3. The 30 cm SMA sampling clock patch cable
4. The CLOCK SMA coaxial cable for external connections of the sampling clock
5. The SYNC SMA coaxial cable for external connections of synchronization
