THATCHAM, U.K.—Phabrix will show new software features for its Qx and QxL rasterizers and the new portable QxP waveform monitor during IBC 2023, Sept. 15-18, at the RAI Amsterdam.

The company, which will be co-exhibiting with its parent company Leader Electronics, also will present its Sx Series of handheld instruments as well as its 2K/3G/HD/SD Rx rasterizers, the company said.

The QxP portable waveform monitor offers the same flexible architecture as the QxL rasterizer and support for 12G-SDI and 25GbE UHD IP workflows. The device offers an integrated 3U multi-touch 1920 x 1200 7-inch LCD screen with integral V-Mount or Gold-mount battery plates, it said.

The new QxP and existing QxL and Qx rasterizers offer the user configurability and advanced tools needed for full operational flexibility when transitioning to next-generation workflows, it said.

New features for the Qx Series include Full Range generation and analysis for comprehensive testing and evaluation as well as enhanced waveform analysis capabilities. The Qx Series takes advantage of the company’s patented DDR-based processing technology. It offers users the precision necessary for tasks like camera shading and image grading while maintaining operational flexibility, the company said.

The latest Rx Series features to be highlighted at IBC 2023 include a new 6-bar gamut toolset to highlight out-of-gamut areas in the picture window. The rasterize series offers gamut monitoring meter bars for the YCbCr and RGB color spaces for pixel-level monitoring at YCbCr and RGB levels at the same time, it said.

The company will also show its Sx Series of handheld instruments.

“Test-and-Measurement instruments are our customers’ lifelines when it comes to rapid fault diagnosis in time critical situations. It’s vital we continue to develop products that support all their formats and production approaches, especially as this industry continues to evolve so rapidly. IBC gives us a fantastic opportunity to discuss our customers’ needs and the latest challenges they are facing,” said Phabrix CEO Martin Mulligan.

LONDON—Production and post house Fifty Fifty here has acquired a Leader LV5600 waveform monitor for use as a master reference for quality control of TV and digital film productions at its Soho headquarters. 

"The LV5600 was a crucial addition to our equipment jigsaw. It provides all the tools we need to ensure conformance with the strict standards laid down by the major video-on-demand content providers,” said Fifty Fifty managing director Alex Meade. “The operating menu is well structured and highly intuitive, as Kevin Salvidge of Leader demonstrated when he visited us to host a very effective training session.”

The waveform monitor offers Cineline and Cinezone tools that enable real-time signal monitoring with the ability to “drill down for closer study” when an element in the signal flow requires a closer look, he said. 

“Measurements are consistent, repeatable and can be stored or exported. Our operators have the freedom to configure the internal display screen to allow precise comparison of multiple signal parameters,” said Meade.

Leader's LV5600 is a mains-powered SDI/IP waveform monitor in a half-rack width 3 RU desktop chassis. It offers a touchscreen front panel display and can be configured to provide all the facilities needed to monitor UHD/HD/SD SDI, as well as video-over-IP signals, seamlessly in a hybrid operating environment. 

Engineering-related features provided as standard include test pattern generation, closed-caption monitoring, CIE color chart, high dynamic range measurement, focus assist, adjustable screen layout, tally interface, 4K/UHD operation, 10G IP input and 12G-SDI interfaces. SMPTE ST 2022-6, SMPTE ST 2022-7 and SMPTE ST 2110 protocols are all supported. 

Distributor Thameside provided the waveform monitor.

Tektronix has been making monitoring and test gear almost as long as I’ve been around and I’ve certainly used my share, beginning with their 535 lab oscilloscope and 529 waveform monitor; that was a long time ago! Tek has always kept up with, or been slightly ahead of, the times and their new model WFM2300 multiformat multistandard portable waveform monitor is a very good example of the good things that continue to emerge from Beaverton. I was fortunate enough to get to test drive this new model and here are my findings.

The WFM2300 is connected to a Blackmagic Design HyperDeck Shuttle 2 for evaluation in the author’s lab.FEATURES
First off, the WFM2300’s moniker “waveform monitor” is something of a misnomer. Yes, it is a waveform monitor, but it’s also much, much more. In addition to responding to just about every type of video signal you’re likely to encounter in a television facility, the WFM2300 is also a precision measurement device and a source of equally precise video—and audio—test signals. I’d use up all of the space allocated for this review if I tried to list everything the WFM2300 can do, but here are some of the highlights.

On the video side of things, it provides: waveforms, vector presentations, eyepatterns, “lightning” displays, timing information, external reference signals (color black or tri-level), exclusive Tek “diamond” and arrowhead color gamut displays, and a high-definition color picture. I should add that the WFM2300 supports SD/HD/3G SDI video. It automatically detects and responds to video formats under test and when an optional SFP transceiver module is installed it works with optically delivered signals.

Test signals delivered by the WFM2300 include color bars and a pathological signal. These are available in all formats—SD/HD/3G— that the instrument is set up for. Also, Tektronix announced (after I’d returned the evaluation WFM2300) some free updated software that significantly expands the number of video test signals available. Included are checkerboard, pluge and luma reference, ChromaDuMonde, clean aperture and more. Other additions include an option for displaying audio/video delay via a bargraph indicator and propagation delay measurement capability for checking codec latency and similiar applications.

As for audio, the WFM2300 is equally feature rich. It allows on-screen monitoring of up to 16 channels of AES audio and allows users to listen to this via a built-in speaker. In addition to bargraph level indications, the instrument offers multichannel surround and Lissajous audio displays. With suitable options, it can function as a loudness meter, Dolby Guard Band meter, and Dolby metadata decoder and peak level meter. The built-in tone generator provides both embedded and discrete digital audio signals. Dolby E audio signal generation is also available as an option.

As this unit is so feature-rich and has so many menus to drill down through, I confined my initial bench testing to cabling up a “loop back” from the WFM2300’s output port to its input BNC. This allowed me to try out many of the unit’s signal generation and display features while ensuring that nothing could go wrong in terms of an outboard device under test not passing signals and causing confusion and consternation. In this early stage evaluation, I soon discovered there are so many displays and settings that I had to do my “test drive” in several installments. (I should mention here that once you’ve figured out the menu structure, the instrument allows you to store up to 32 test configurations for instant recall, thus saving a lot of time in calling up frequently used test setups.)

Once I felt that I’d mastered most of the WFM2300’s menus, I broke the I/O loop connection I’d set up and brought in an outboard device to take the place of the length of RG-6 coax I’d been using. This was a Blackmagic Design HyperDeck Shuttle 2 capture and playback device.

Once the Shuttle 2 was connected to the WFM2300 and powered up I proceeded to “lay down” several minutes of color bars and tone. Once this was accomplished, I went for playback and while this was in progress I walked through a number of the WFM2300’s display and measurement “pages,” including the very rigorous measurement of all of the SDI signal parameters. Like everyone else making the shift to digital video a number of years ago, I was taught that “digital is perfect,” however, even though the Blackmagic folks have a well-established reputation for perfection in their products, I was sort of hoping for one teeny-tiny parameter to be out of the box, but this wasn’t the case. Even though the Tek WFM2300 gave it a complete workout, nothing in the video output raised even the slightest flag when the “numbers” came in. I next tried the Tek pathological stress test and the Blackmagic box again passed with flying colors. Other testing included synthetically adding some extra cable, which is easily done with the WFM2300, to see if I could push things over the “digital cliff.” No such luck here either. The Shuttle 2 kept on precisely ticking!

Before shutting down the WFM2300 I also tried out its freeze frame capability with some “in motion” video previously captured on the Shuttle 2. I also tried out the cursor-select feature that allows you to very accurately perform measurements on a very small portion of a complex waveform. I won’t go so far as to say that the WFM2300’s measurement possibilities are “endless,” but the user manual is a very thick document.

SUMMARY
Following Tektronix’s very long tradition of building very high quality test gear, the WFM2300 is certainly no slacker. It represents Tek’s latest offering into the world of HDTV and provides just about everything that one could want in test generation and measurement capability. If you’re moving from SDI on copper to fiber, the WFM2300 is ready for this too. The instrument is also firmware-field-upgradable to handle video’s future as it develops. Although I didn’t perform a “drop” test, the device’s housing looks as if it could stand up to most of the abuse offered by studio and field use. The only downside I found was a slight bit of noise from the internal fan (there is a lot of silicon to cool in this compact package), but this was not particularly annoying and really didn’t mask any audio issuing from the unit’s internal speakers. The price tag may make some of us a bit apprehensive, but it’s a very true adage in the world of TV test gear that you get what you pay for. In fact, I still have a Tek 529 waveform monitor and 526 vectorscope in my lab that still perform perfectly despite their having been manufactured about half a century ago!
