The Rohde & Schwarz UAF Video Analyzer is a precision instrument for in-depth testing and analysis of video signals across broadcast, research, and development environments. It delivers studio-quality measurement accuracy through a combination of analog signal conditioning and digital processing, with a 12-bit A/D converter ensuring high-fidelity results. The instrument analyzes 25 video and test line parameters—including levels, linear and non-linear distortions, 2T K rating, frequency response, and hum—with freely selectable test line positions across the entire picture area and field blanking interval.
Technical Specifications
• Signal Analysis: 25 video and test line parameters including levels, distortions, 2T K rating, frequency response, hum
• Test Line Selection: Freely selectable across entire picture area and field blanking interval
• Test Configurations: Storage capacity for up to 8 configurations
• Integration Time: <1 s, 2.5 s, 5 s, or 10 s (adjustable)
• Measurement Times: Seconds range
• Signal Inputs: 3 x 75 Ω video inputs with loopthrough filters; configurable as 3 x CCVS or 1 x Y/C + 1 x CCVS
• Input Signal Level: 1 V pp ±6 dB
• Synchronization: Internal, from any of 3 inputs (sync pulse 300 mV ±6 dB), or external via dedicated loopthrough input
• A/D Conversion: 12-bit converter for test circuit output and video signal portions
– Key Features
• Variable integration time optimizes measurement stability for studio alignments (<1 s) or noisy signals and long transmission links (5–10 s)
• Noise voltage measurement with selectable weighting filters
• Difference measurement between two inputs for error elimination at DUT input
• Reference measurement storage for single test cycles
• Limit monitoring with two upper and two lower adjustable limits per parameter, with blinking LED indication, optional acoustic alarm, and error logging
• AUTORUN routine support for user-defined automated test sequences
• Studio-quality measurement accuracy
– Typical Applications
• Broadcast signal compliance and quality assurance
• Video transmission link analysis
• Device Under Test (DUT) characterization and validation
• Production and studio alignment
