Fast spectrum analysis now through to 40 GHz: Spectrum Analyzer FSEM/FSEK
There are new additions to the FSE spectrum analyzer family: in Spectrum Analyzer FSEM Rohde & Schwarz has now moved into the microwave range through to 26.5 GHz and, with FSEK, for the first time through to 40 GHz. New on the world market is a vector signal analyzer option which allows modulation analysis of digitally modulated signals at these frequencies. Standards of measurement speed, precision, dynamic range and spectral purity, set by FSE in the RF range, are of course maintained by the latest members of the family in the microwave range.

Innovations in ATC radiocommunications: RCMS and 8.33-kHz channel spacing: Series 200 and 400U radio equipment
Reliability has top priority in ATC radiocommunications as human lives are at stake. Central and flexible remote control and monitoring systems (RCMS) as well as the 8.33-kHz channel spacing planned for 1998 contribute to safety. For this reason Rohde & Schwarz has logistically upgraded its ATC radio equipment: Series 200 now comes with RCMS and 8.33-kHz channel spacing. Series 400U is also available with 8.33 kHz. Thus the customer is already provided with ultramodern and future-proof solutions.

Top fit for digital television: TV Test Receiver Family EFA
Small-size, compact, future-oriented, upgradable – this is how TV Test Receiver Family EFA shows its true self. With this family Rohde & Schwarz has created a test platform that can easily keep pace with rapid developments in television. Before the official start of digital video broadcasting, Rohde & Schwarz can already offer the world’s first demodulator for QAM signals which is able to perform all the measurements required on cable digital channels. An analog TV test receiver – either broadband or selective – is available for monitoring the previous TV channels. Digital and analog functions can also be combined in single unit, which can be expanded by adding options.

EMC measurements up to 40 GHz with Microwave Signal Generator SMP:
Apart from an RF signal of high spectral purity and precisely adjustable output power, signal generators for EMC measurements require top-quality AM and pulse modulation, spike-free frequency and level sweeps and last but not least a mature operating concept permitting automatic measurement sequences to be performed with or without an external controller.

Measurements on hearing aids with Audio Analyzers UPD and UPL:
The ear is an extremely sensitive organ. If healthy, it is capable of processing sounds with an extremely wide dynamic range. Nevertheless, it can easily be damaged by longterm exposure to, say, industrial noise or excessive noise levels in discos or from walkmen. As the effect on hearing is often only noticed later on, there is an increasing number of young people with hearing defects that have to be corrected with a hearing aid.

Quality testing of mobile phones using multitone audio analysis of Digital Radiocommunication Tester CMD:
Europe is not the only place where digital GSM and DECT networks have flourished. Variations of these networks are taking hold all over the world, but the market is by no means saturated. Manufacturers of mobile phones still have to woo the customer to win orders.

Tailor-made applications in industrial automation with factory user port for Controller PSM:
Automatic testing often requires only relatively simple functions for setting and evaluating a DUT, eg a mobile phone. For these purposes Industrial Controller PSM (FIG 1) [1; 2] is equipped to standard with the factory user port (FUP), a universal interface. This means that a multitude of applications can be implemented without any additional hardware. The supplied software library considerably reduces the time required to become familiar with the FUP and its operation.

Fast adaptive data transmission on shortwave at up to 5400 bit/s with HF Modem GM2100:
When it was first introduced, shortwave data transmission was limited to 200 bit/s. This was because of the problem of multipath propagation in shortwave communications. Error control methods such as FEC (forward error correction) and ARQ (automatic repeat request) ensure minimal bit error rates.
