Rohde & Schwarz: Test Transmitter for Broadcast
Test transmitter.
Munich, Germany — Rohde & Schwarz's new SFE100 test transmitter for broadcast production delivers price-performance advantage. The test transmitter targets production test applications for set-top boxes, TV sets, and other broadcast terminal units and modules. The unit combines an RF signal generator, power amplifier, and baseband generator into a compact package with an attractive price/performance ratio.

By providing multiple functions in a single unit, it lowers purchase and operating costs, increases reliability, and simplifies maintenance. It is designed as a single-standard test transmitter and comes in several models to handle common terrestrial, satellite, cable, and mobile TV standards as well as a number of sound broadcasting standards.

The signal generator's real-time coders deliver endless and seamless test signals. This is particularly useful in production applications because the signal generators do not have to be synchronized with the production cycle. Moreover, modulation parameters can be set as required for each transmission standard. Users can, for example, define the constellation, code rate, and FFT mode. These parameters can be varied independently of the transport stream or A/V signal to be transmitted. This allows all conceivable versions of a standard to be tested. The real-time coder automatically adjusts the corresponding signaling information for the receiver.

The unit can be equipped with an optional power amplifier that has a maximum output power of 27dBm. This higher signal level makes the instrument an excellent choice for use in production test systems in which the signals of multiple test transmitters are combined in a coupling network and distributed over large distances. To compensate for the accompanying losses, a high signal level is required.
