LEADER’S MODULAR MULTI-FORMAT VIDEO & SYNC-PULSE GENERATOR
Leader Instruments is introducing a multi-format video and sync pulse generator to its broadcast test equipment range. Integral to the design of the LT8900 is an extensive library of reference and test signals that meet current signal standards, and will be developed to accommodate the future standards to match the fast pace of progress in global broadcast markets.
Developed both for testing broadcast systems and as a master timing reference, the 1RU instrument supports a selection of optional features that can be activated or upgraded locally or remotely.
The LT8900 can generate 1080/720 HD and 625/525-line standard definition reference and test signals simultaneously, with independent timing control for all outputs to simplify system integration. HD and tri-level sync formats are accommodated either within the base unit or by fitting the appropriate option board. HD test patterns are available in all recognised 1.485 gigabit/s standards or, with the optional 3G output board, in any of the extended 2.970 gigabit/s formats. Externally generated test patterns and logos can also be imported.
A plug-in GPS receiver module available as a hardware option provides a stable and robust method for accurately locking multiple units. GPS can also be used as a precise timing reference for the LT8900’s linear timecode, vertical interval timecode and Network/Precision Time Protocol (NTP/PTP) outputs.
Remote status monitoring of critical functions can be achieved via Serial Network Management Protocol (SNMP). Accurate GPS referencing is managed either via the receiver module or by locking to an external source of one pulse per second and NMEA serial data, guaranteeing the synchronisation of all video, audio, PC-based devices and system clocks.
Special attention has been paid to the audio section with multiple audio generators assignable for AES, embedded HD/SD, wordclock and analogue stereo audio.
The Vector remote configuration browser is included in all LT8900 models and allows remote adjustment and monitoring of all system parameters, in addition to managing software and feature upgrades.
Dual LT8900 units can be deployed as a main and reserve pair for enhanced security, together with a Leader LT8910 intelligent changeover module, which monitors the integrity of the main and reserve reference signals and automatically switches to the reserve unit if necessary. Optional boards for detection of tri-level sync, LTC, AES and SDI can also be fitted.
Individual options available for the LT8900 include a reserve power supply module, full field test pattern software, linear timecode software, GPS receiver and software, GPS antenna and universal mount, unbalanced AES output card, tri-level sync module, NTP server support, SNMP support and 3G high-definition output card. Four pre-packaged versions offer a combination of these options.
The LT8900 will make its debut at the NAB show in Las Vegas, April 13 to 16.
