Reference Presence
– the only reference available for
the IPG-4901 is the Universal Reference Signal (URS)
generated by the GV Node frame controller’s reference
module.
The reference may be available in 50 Hz and/or 59.94 Hz – a green icon indicates the presence of each format.
4.4.2 Reference Panel – PTP tab
IPG-4901 extracts PTP (Precision Time Protocol) data for streaming (RTP Timestamp) and AES-67 reception. The
card still needs the GV Node’s URS reference.
