The R&S SFQ TV Test Transmitter offers a solution for testing digital TV links and receivers (set top boxes). An open end software system and modular hardware configuration make the SFW future proof. The ETSI standars for DVB-T, DVB-S, DVB-DSNG and DVB-C as well as ATSC/8VSB and ITU-T/J.83B (US cable) standard for DTV are full complied with.

In addition to digital signal processing, the Rohde & Schwarz SFQ also processes analog frequency modulated satellite signals in line with PAL, SECAM and NTSC standards. The sound signals are transmitted using analog FM and digital ADR sound subcarriers.

Features and specificaitons of the R&S SFQ include:

Wide output frequency range from 0.3 MHz - 3.3 GHz
Large output level range for transmission, receiver and module measurements
Standard DVB, ATSC, ITU-T/J.83B signals and FM satellite signals
Several standards in one unit
Satellite FM
* FM and ADR sound subcarrier
Antenna DVB-T
* 2K and 8K COFDM
* 6/7/8 MHz bandwidth
* Hierarchical Coding
Antenna ATSC
* 8VSB
Cable DVB-C
* Selectable QAM: 16, 32, 64, 128, 256QAM
Satellite DVB-S, DVB-DSNG, Turbo Coder
* QPSK, QPSK Turbo
* 8PSK, 8PSK Turbo
* 16QAM
Internal Noise Generator for high precision C/N Settings
Internal bit error measurement for all digital modulation modes
Internal fading simulator
* 6 or 12 paths
* Predefined profiles
* User definable profiles
Flexible input interfaces
Output and input for external I/Q Signals
