Changeover
LT 4448
LThe LT 4448 is a changeover unit that automatically switches the signal from the primary signal to the backup signal when problems are detected in the primary signal.Two systems of input signals (primary and backup) are connected to the LT 4448, and the LT 4448 detects errors in the amplitude of the primary input signal.A single LT 4448 provides 11 pairs of BNC and LTC channels. These channels can receive SDI, NTSC/PAL black burst, HD tri-level sync, AES/EBU digital audio, word-clock, and LTC signals.It can be used in combination with the LT 4610 (Sync Generator).

Advanced Test Platform
980 12G
The Teledyne LeCroy quantumdata 980 12G-SDI Video Generator / Analyzer module supports video and audio functional testing of next gen broadcast monitors, conversion devices and sources up to 12G-SDI. The module is equipped with four (4)12G-SDI-capable output ports. The output ports can be aggregated for Dual link HD-SDI and Quad link 3G-SDI operation. A genlock input supporting both SD analog black burst and HD tri-level to sync the output clocks with a "house sync" but the module can also run off its internal clock. The module's four (4) SDI input ports can also be aggregated for Dual link HD-SDI and Quad link 3G-SDI operation. For single link operation only port 1 on the input or output is functional.

Sync Generator
LT 4610
The LT 4610 is 1RU full-rack size sync signal generator that can output triple-rate SDI (3G-SDI/HD-SDI/SD-SDI) signals. It employs two power supply units for redundant operation to protect against power supply failures. The genlock function for external sync signals enables SDI signals, six sets of analog black burst sync signals, and audio word-clock signals to be output synchronously. The genlock function is equipped with a STAY IN SYNC function that maintains the phase when errors occur in the input signal, making it possible to provide stable sync systems.In addition to test pattern output including color bars and SDI check fields, the LT 4610 can embed ID characters, QVGA logo marks, safety area markers, and embedded audio in a SDI signal output.
