SDI Inputs (BNC)
The Physical Layer input connection for eye and jitter is the rightmost BNC (when viewed from the rear) with a
red nut. This provides the multirate eye and jitter connection from 1.5G HD-SDI to 12G-SDI. There are four 12G-
SDI capable input BNCs for the analyzer: SDI IN A, B, C, D.
Up to four SDI inputs may be connected at any one time, however the system will automatically determine
the signal set to analyze - be it single link, dual link, or quad link - based on the SMPTE ST 352 packets
present. The algorithm looks to ‘SDI IN A’ first and then determines the overall standard.
If the SMPTE ST 352 packets are known to be incorrect then the user has the option to select ‘Ignore
payload identifier packets (ST 352)’ in the ‘Analyzer - Video Standard’ window.
This software release introduces SDIBNC In -to- SDI BNCOut signal passthrough via the 'Loop' feature in
'System IO', making the input SDIsignal(s) available on the SDI BNCoutput connection.
SDI Outputs (BNC)
The generator provides up to four SDI output signals which must form part of the same video signal set.
When 'SDI BNC Out - Generator Output Copy' mode' is enabled it will provide either:
l x4 single link
l x2 dual link
l x1 quad link
‘SDI OUT A’ is always present and carries the first signal in the group. ‘SDI OUT B’ is active for dual link
standards, and ‘SDI OUT C’ and ‘SDI OUT D’ are active for quad link standards.
If ‘Output Copy’ mode is not enabled, a single instance of a link standard will be generated:
l x1 single link
l x1 dual link
l x1 quad link
When the ‘Loop’ feature is enabled, the Qx generator wil be disabled, and instead, the SDI BNC Outputs will
be provided as output signals the SDI BNC Input signals the Qx is receiving. The 'SDI BNC Out - Loop SDI BNC
In' internal passthrough signal routing works as follows:
l ‘SDI BNC In A’ -> ‘SDI BNC Out A’
l ‘SDI BNC In B’ -> ‘SDI BNC Out B’
l ‘SDI BNC In C’ -> ‘SDI BNC Out C’
l ‘SDI BNC In D’ -> ‘SDI BNC Out D’
Note: The 'Output Copy' feature cannot be used at the same time as the 'Loop' feature. Enabling the 'Loop'
feature disables the generator activity on the SDI BNC outputs, and overrides 'Output Copy'.
Note: The 'Loop' feature is available when both the 'SDIInput Source' and 'SDI Out' are set to 'BNC' only.
('System IO' SDI connector configuration: BNC in / BNC out.)
SDI SFP Connections Overview
The Qx has two available SFP slots that can be used for SDI SFPs. These slot are labelled SFP+A and SFP+B.
Each slot can house an SFP that itself has one or two signal lanes.
The signal lane can either be an Rx (receiver/input) or Tx (transmitter/output).
