Rohde & Schwarz SFM-B16 Transmission Test Set

The Rohde & Schwarz SFM TV Test Transmitter is a flexible modularconcept based on plug-ins (freely selectable). The is SFM suitable for awide range of applications.By virtue of the highly compact design, agreat number of different configurations can be implemented in a singleSFM.Depending on application and configuration, the SFM may be used as:

Multistandard signal generator providing vision and soundmodulation signals for up to seven TV standards (B/G, D/K, L/L', I, M,N, K1) including sound as is required by the dual-carrier method orNICAM-728 as well as an RF upconverter used as a tunable test signalsource
RF upconverter with a maximum of three separately settable converters for adjacent-channel and intermodulation measurements
IF modulator comprising several vision/sound modulators tovarious standards equipped for use in multichannel and multistandardsystems

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 onoperating mode (optimum signal-to-noise and signal-to-intermodulationratio)
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 Ohm (female N) or optional 75 Ohm (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
