The Rohde & Schwarz SFM TV Tester (model 2007.9106.50) is a modular TV test transmitter for generating and analyzing vision and sound signals across all currently used broadcast standards. The instrument automatically configures standard-specific parameters while enabling full manual adjustment across wide ranges to create non-standard test signals for limit-value determination and compliance verification. Its modular plug-in architecture provides customization for diverse measurement and production applications.
Technical Specifications
Signal Generation
• Vision and sound signal generation for all current TV standards
• Automatic parameter configuration per selected standard
• Wide-range parameter variation around standard values
• Single-keystroke restoration to standard compliance
Vision Modulation
• Vestigial sideband (VSB) amplitude modulation to specification
• Independent switchable VSB SAW filter and group-delay precorrection
• Double-sideband test modulator operation across 32 MHz to 46 MHz intermediate frequencies
• Continuously variable vision modulator parameters
Audio and Sound Modulation
• Dual sound modulators (FM and AM) with wide parameter variability
• Stereo/dual-sound coder (IRT/Korea standard)
• NICAM QPSK modulator with 0 Hz to 15 kHz generator
