Note: VIB-X cards shipped before August 2011 (cards with SN < 10018473) only support LED
diagnostics but do not support enhanced diagnostics, which provides card serial number information
and a video test pattern generator.
The VIB-X replaces the older video cards VIB-TX and VIB-RX, including filter daughtercards, with a single
assembly that is switch configured to behave as a VIB-TX card (video input) or VIB-RX card (video output).
VIB-X cards are backwards compatible with the older VIB-TX and VIB-RX cards and may be paired with them
for standard video signal formats. Although designed to take advantage of -X backplanes, VIB-X cards are
also backwards compatible with older Model 903 backplanes. The only difference between the VIB-X versions
of VIB-TX and VIB-RX cards is the factory switch setting.
4.2.1.1 Input/Output
VIB-X video inputs and outputs are compatible with standard composite signals (NTSC, PAL), Y/C or S-video
formats, and component video formats RGB (sync on G) and YPrPb. Inputs and outputs have 75-ohm
impedance with ESD protection and should be used with high quality, 75-ohm coaxial cables, such as
RG-179. Mating connectors should be "Mini" 75-ohm SMB plugs, though 50-ohm SMBs are compatible and
acceptable for video bandwidth signals. Inputs should be standard video levels, typically 1.0 to 1.2 Vpp.
Signals will start to clip at 1.4 Vpp, and absolute maximum levels are 3 Vpp. Input bandwidth is limited to
6 MHz by anti-aliasing filters.
