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
