Leader Showcases LV5770 Broadcast Signal Analyser At BVE North

Leader Instruments has selected BVE North in Manchester as the UK launch venue for a new audio card for the LV5770 Multi-Monitor.
The company will be represented on stand D39 by Chris Margrave-Gregory and Alex Small from Leader's UK master distributor Thameside TV.
The OP43 audio card incorporates loudness measurement, lip-sync timing analysis and surround-sound monitoring. These new features double the total number of audio capabilities currently available for the LV5770 which already include 16-channel AES/EBU embedded audio input/output, Dolby Audio evaluation and decode as well as 8 channel discreet or embedded digital to analog signal conversion.
Leader's LV5770 departs from the expensive pricing associated with high-definition test equipment over the past decade. The new OP43 option reinforces the LV5770's position as the most affordable and the most versatile signal analyser in the broadcast industry. The module's loudness measurement capability allows camera crews, post-production staff and playout supervisors to ensure that content is compliant with the demands of the US Commercial Advertisement Loudness Mitigation Act and its European equivalent, EBU Recommendation 128.
Lip-sync timing will be appreciated throughout the production, post and playout chain, given the wide disparity between video and audio processing times that can arise between initial signal acquisition and the moment of transmission. Surround sound analysis is also incorporated for use by audio balancers during live mixing and in post-production.
Leader’s LV5770 is a compact broadcast signal analyser supporting 3G, HD dual link, HD-SDI and SD-SDI signal formats. Its modular design allows easy customisation to meet a user’s specific needs. Signal amplitudes, vector, data, colour bars and programme picture can be viewed individually or in quad-split mode on the instrument’s integral 6.3 inch XGA LCD screen. Video frames can be captured manually or on an automated error-detection basis. Video display options include eye pattern and jitter waveform. Eye pattern rise time, amplitude, fall time, timing jitter, current jitter, rising-edge overshoot and falling-edge overshoot can be measured automatically.
An Ethernet interface can be used to control the LV5770 remotely over Telnet, detect remote system errors via SNMP, forward files via FTP or perform other operations from a connected PC. The remote control connector can be used to load presets, switch the input signal, and transmit error logs.
The OP43 audio card for Leader’s LV5770 Multi-Monitor is available now.
