Rohde & schwarz r&s sfm tv test transmitter messender
Vision and sound signals to all common TV standards
Key FactsPicture R&S SFM TV Test Transmitter
The flexible modular concept based on plug-ins (freely selectable) makes the SFM suitable for a wide range of applications.By virtue of the highly compact design, a great number of different configurations can be implemented in a single SFM.
Depending on application and configuration, the SFM may be used as
* RF upconverter with a maximum of three separately settable converters for adjacent-channel and intermodulation measurements
* IF modulator comprising several vision/sound modulators to various standards equipped for use in multichannel and multistandard systems
The most important features of the SFM are:
* Generation of TV RF/IF signals (vestigial sideband amplitude modulation) to specified standards
* All vision and sound modulation parameters variable in wide ranges about standard values
* Vestigial sideband filter (SAW) and group-delay precorrection can be separately switched on/off
* Double-sideband test modulator for all IFs between 32 MHz and 46 MHz
* RF upconverter from 5 MHz to 1000 MHz; suitable for back-channel operation in analog and digital modulation modes
* Switchover between upper and lower sideband at RF
* Maximum RF output level from +10 dBm to 0 dBm depending on operating mode (optimum signal-to-noise and signal-to-intermodulation ratio)
* Non-interrupting level reduction down to -14 dB
* RF frequency resolution 1 kHz or 1 Hz for precision offset
* Frequency locking for all oscillators via internal 10 MHz reference frequency or external precision reference frequency
* RF output impedance 50 (female N) or optional 75 (female BNC)
* AF generator, 30 Hz to 15 kHz, and stereo/dual-sound coder (IRT/Korea)
* Wideband audio input for BTSC signals up to 120 kHz (standard M)
* NICAM QPSK modulator with generator for frequencies from 0 Hz to 15 kHz, adjustable BER, PRBS and I/Q test sequences
* NICAM intercarrier output adjustable between 5 MHz and 9 MHz, digital data/clock inputs/outputs for 728 kbit/s
* Instrument settings storable in internal memory or on memory card (PCMCIA)
* System-compatible due to IEC/IEEE-bus and RS-232-C interface
* Connectors for external keyboard and external monitor
