Bexel Selects Leader's LV5490

News Image
Bexel has announced it has invested in Leader's LV5490 4K/HD/SD waveform monitor. The instrument is an important element of the 4K engineering support resource at Bexel's headquarters in Burbank, California.

"Demand for 4K is slowly catching on and we see it as having a great future given to the increasing affordability of 4K production equipment and 4K home television displays," comments Tom Dickinson, Chief Technology Officer at Bexel. "It is also a natural format for digital film and video content producers keen to preserve the value of their content. In the long term, 4K will upconvert to 8K far better than any HD original when the Super Hi-Vision display format begins to fly around 2020."

"We have a lot of Leader products in our test racks and in our rental fleet," adds Bexel's Director of Engineering, Edd Bonner. "They work very well, especially on location where their compact size and rugged build are a definite advantage. The LV5490 is an ideal tool for anyone serious about delivering the full sharpness, contract ratio and colour depth of 4K. Having UHD, HD and standard definition capabilities in a single unit is also very useful in post-production as we can compare transcodes in detail on the LV5490 screen or side-by-side in multi-display mode."

Equipped with eight input connectors, the Leader LV5490 accepts up to two 4K signals simultaneously. In the 4K video format mode, 3G-SDI dual link or quad link is supported. Up to four 3G-SDI dual link 4K video inputs or up to two 3G-SDI quad link 4K video inputs can be displayed (selectable). Two sets of HD-SDI dual link signals can be displayed (selectable). In the SDI mode, up to four signals can be displayed simultaneously. The LV5490 is also equipped to handle video signals via two-sample interleave as well as square division. Two-sample interleave is the approved standard for 4K.

The LV5490 can be operated in a wide selection of test and measurement roles; these include waveform, vector, picture monitoring, SDI signal status (which looks for cyclic-redundancy-check errors and embedded-audio errors), an event log, data dump and four-channel timing display. Leader's CINELITE II toolset also comes as a standard feature, which includes CINELITE and CINEZONE, allowing easy assessment of relative exposure and overall luminance.

Waveform, vector and picture display can be viewed simultaneously on the LV5490 screen. Simultaneous display and overlay display of multiple SDI inputs is possible. Size and location of individual channel displays can be adjusted using a USB mouse. The LV5490 can also be controlled remotely using standard KVM tools.

In addition to its video test and measurement capabilities, the LEADER LV5490 incorporates a selection of audio monitoring and analysis tools, which are available with the Digital Audio option. These include 4 x 4 channels of SDI audio de-embedding, lissajous display, surround sound display and volumetric display. Up to 16 channels of de-embedded SDI audio can be displayed on screen and output as discrete AES3 feeds.

Additional features of the LV5490 include video frame capture, instrumentation screen capture, timecode display, ID display and a 4K pattern generator, with embedded audio. Eye pattern, including jitter waveform display and Dolby decoding, can be ordered as optional facilities along with a CIE 1931/1976 colour space chart, which can display BT.709, DCI (P2) plus BT.2020 which is the 4K standard's full ITU recommended color space.

LV5490 operators can adjust the size of up to four displays on the screen to suit specific tasks. This allows magnification and inspection of detail on the instrument's 9 inch 1920 x 1080 HD LCD display screen instead of being limited to fixed size quadrants. And, if the 9 inch display is not large enough for the operator, the LV5490 also comes with a 1920 x 1080 HD DVI and HD-SDI rasterized output for display on a larger monitor.

Fully portable, the LV5490 has a footprint of just 8.77 inches wide by 14.7 inches deep and a height of 7.44 inches (223 x 360 x 189 mm). The instrument weighs 10.4 pounds (4.72 kg). A rack mounting adapter is also available.
