Our target was to develop a spectrum Analyzer belonging to the best which engineers, scientists and technicians can currently buy on the market. The result is the FSA — an instrument which sets completely new standards. How? Primarily as a result of its technical performance, high operating convenience and its future-oriented concept. The FSA enables applications and measurement qualities which were previously unattainable. The sensitivity, phase noise, frequency response and resolution bandwidths have values which are truly in the high. The FSA is as easy to use as a pocket calculator. It carries out a selftest as soon as it is switched on. If you then want to select basic functions, it is no longer necessary to use 2 or even 3 steps. The pressing of one key is sufficient. Setting parameters can be coupled for signal analysis. You only need to change one value, all others are adapted automatically. For example, the ratio between resolution bandwidth and video bandwidth. If repeated measurements are necessary, you can store instrument settings and recall them as required. Measuring sequences can be executed automatically when using the controller function. A built-in RF limiter protects the FSA and can detect overloads, even outside the displayed frequency range. Right from the beginning we designed the Spectrum Analyzer FSA as a flexible instrument. It provides a "system solution" and not an "isolated solution". This guarantees upward-com-patibility. The FSA can handle any new task and any increase in complexity whether as an individual instrument or a complex test system. Hardware and Software can be extended and modified without problems. The decision to purchase the Spectrum Analyzer FSA is therefore also a decision in favour of sensible investment. Modular hardware Hardly any other spectrum Analyzer can provide the perfect modular and extendable hardware solution of the FSA. The instrument is divided into a display unit and an RF unit. The display unit can thus be combined with all other RF units of the spectrum Analyzer family from Rohde & Schwarz. Externa! screen A separate colour monitor or a large-display beamer can be connected via an RGB output for special workstations or for training and presentation purposes. External keyboard The Keyboard PCA-Zl provides even more convenience for screen documentation. The Spectrum Analyzer FSA is used to measure the spectral distribution of signals in the frequency range from 100 Hz to 1.8 GHz (2 GHz). The quasi-con-tinuously variable frequency resolution and the precise Synthesizer tuning with long-term stability means that the spectrum Analyzer is suitable for swept-frequency analysis as well as for selective level measurements in the fixed-frequency mode. The large range of resolution bandwidths (6 Hz to 3 MHz), the frequency span (0/10 Hz to 2 GHz) and the level display (1 to 110 dB) in a measuring range of 175 dB (—150 to -1-30 dBm) predestine the FSA for all selective level measurements. Level measurements on generators □ Small resolution bandwidths (6 Hz) □ High frequency resolution (0.1 Hz) □ Low phase noise (<—110 dBc (1 Hz) at 1 kHz from the carrier) □ Frequency Counter Level measurements on modulators □ AM/FM demodulators as standard □ Wide dynamic range and high linearity of AM measurement display Level measurements on broadband systems □ Flat frequency response (<0.6 dB) □ High sensitivity (<—150 dBm) □ High overload immunity (intermodulation suppression >100 dB) □ Wide resolution bandwidths (3 MHz)
