Tektronix Adds New Capabilities to its Sentry Line of Digital Content Monitors

Tektronix, the market leader in broadcast video test, monitoring and analysis solutions, today announced that it has added significant new features and capabilities to its award-winning line of Sentry® digital content monitors, which are widely used by cable television operators and other video service providers (VSP) to help deliver services with optimal video and audio quality.

"We are continually adding new features, functions and capabilities to ensure our Sentry line addresses VSPs' most urgent requirements, from improving the early detection and diagnosis of video and audio issues to regulatory compliance," said Eben Jenkins, general manager, Video Product Line, Tektronix. "This commitment to regularly enhancing Sentry is one of the key reasons it remains the industry's most advanced solution for ensuring quality of experience (QoE)."

The latest capabilities added to the Sentry line are enabled by its latest software release. These new capabilities include:
  • The ability to capture "thumbnail" images of programs, which enables VSPs to validate program content and verify when program outages have occurred.
  • An ad cue report that combines thumbnails with audio level graphing to create a single report capturing all the data that VSPs need to provide the FCC to demonstrate compliance with the Commercial Advertisement Loudness Mitigation (CALM) Act. This report provides visual validation of ad presence, that the correct ad aired at the appropriate time and during the right program, as well as noting whether the ad was too loud or too quiet.
  • Enhancements to Sentry's unique Perceptual Video Quality (PVQ) capability (which gauges precisely how much video compression artifacts impact viewers) that is now sensitive to certain artifacts caused by over-compression that specifically affects chroma detail.
The award-winning Sentry is the industry's premier content monitoring solution, used by leading VSPs to identify and diagnose video and audio errors in MPEG-2 and H.264 content that can impact viewers' quality of experience (QoE). Sentry is proven in deployments with nine of the top 10 U.S. cable operators and four of the top five Canadian operators.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…
