For immediate release

See Leader on Booth C5109 at 2016 NAB Show, Las Vegas Convention Center, April 18-21

Fullerton, California, March 18, 2016:
Leader Instruments, a wholly owned subsidiary of Leader Electronics Corporation, Yokohama, Japan, announces two new options for its LV7390 rasterizer. These comprise full 4K signal measurement capability plus a plug-in digital audio module providing up to 16 channels of de-embedded SDI audio which can be viewed on screen and output as discrete AES3 feeds.

Both options will be introduced and demonstrated on the Leader Booth (C5109) at the 2016 NAB Show in Las Vegas, April 18-21.

The LV7390 is a 3G/HD/SD-SDI rasterizer which can be used to monitor up to four sources at the same time. Compatible with 3G/HD/SD-SDI, and now optionally 4K, the unit can also monitor up to eight channels of embedded audio as standard. The instrument incorporates full-resolution 3G/HD-SDI and DVI-I rasterized outputs which allow detailed video and audio measurements to be checked on a separate monitor in full 1920 x 1080 HD resolution.


Waveform, vector, picture, audio and SDI status can be viewed full screen or in a multi-display. The multi-display layout is user-customizable and can be configured with a standard USB mouse, then saved for fast recall. 60 user-definable presets are standard. These can be labeled and displayed on-screen. The LV7390 can also be controlled remotely using a USB mouse.

A screen capture function allows the LV7390 operator to save the displayed image and measurements as a BMP file on removable USB memory. This feature can be used for matching cameras or documenting a shot for purposes such as continuity or technical trouble-shooting.

Transmission line measurement for each SDI input can be displayed numerically in terms of equivalent cable length, allowing the safety margin to be checked quickly.

Video Engineer controls are provided for use in camera setup during shading.

The integral Leader CINELITE® feature allows the user to measure luminance levels at up to three different points in a scene. CINEZONE® uses false colors to indicate luminance levels in a scene and is particularly suited to green-screen chroma-key virtual-set alignment.

Additional features include error logs and alarms, format and timecode displays, SDI analysis plus a data dump and information on a variety of error monitoring functions such as CRC, TRS position, illegal code,  line number SDI errors, checksum and parity ancillary data errors, BCH, DBN, inhibit, and embedded audio errors. Ethernet connectivity allows remote control via an internet or extranet connection. The LV7390 supports TELNET, FTP, HTTP, and SNMP protocols.

The LV7390 Viewfinder option provides separate SDI inputs which can display signals from up to four cameras, or the camera menu. This feature allows camera operators to monitor the settings of remotely located cameras, from a studio control room or mobile production truck.

The LV7390 operates on 90-250 volt 50/60 Hz. Power consumption is 90 watts maximum. Just 1 RU in size, it can be deployed for desktop or rack-mounted operation.

Leader Instruments Corporation

Leader Instruments Corporation produces high-quality future-proof test and measurement equipment. Since its establishment more than 60 years ago, Leader has earned a worldwide reputation for designing and manufacturing some of the most reliable and practical electronic instruments available. Leader products were originally developed for production testing and servicing. These are applications in which ease-of-use and highest reliability are essential. By expanding into a broad line of industrial and video instruments, Leader was able to add to these fundamental qualities a degree of cost-performance excellence unequalled in the industry.

Quality is built in every step of the way using the finest components for optimum reliability. Sub-assemblies are separately tested before being integrated into the finished product, which is then further tested. Less than 1% of all Leader products made are ever returned for warranty repair or adjustment. Leader products, ranging from 4K waveform monitors to rasterizers and video test equipment, are specified for research, development, broadcast, production and service applications.
