R&S®SMA100A Signal Generator At a glance Signal quality, speed and flexibility – these are the criteria by which signal generators are measured today. The R&S®SMA100A perfectly meets these criteria, and thus is a premium-class analog generator that sets new standards due to its outstanding characteristics. The R&S®SMA100A combines superior signal quality with very high setting speed, which makes it ideal for any task.
R&S®SMA100A Signal Generator Benefits and key features Excellent signal quality ❙❙ Very low SSB phase noise of typ. –134 dBc (20 kHz carrier offset, f = 1 GHz, 1 Hz measurement bandwidth), typ. –139.5 dBc with the R&S®SMA-B22 enhanced phase noise performance option ❙❙ Wideband noise of –162 dBc (meas.
Excellent signal quality The R&S®SMA100A is the ideal solution for m easurement applications requiring high s pectral purity, e.g. adjacent- channel or phase-noise measurements. It is also optimal for use as a local o scillator or quartz replacement. Due to an innovative synthesizer concept, the standard version of the instrument already offers excellent values in terms of broadband noise, SSB phase noise and nonharmonics suppression.
Ideal for use in production In production and ATE applications, the test equipment must provide short setting times in order to ensure high throughput and low measurement costs. The R&S®SMA100A features the very short level and frequency setting times that Rohde & Schwarz signal generators are known for and is thus an ideal choice in time- critical measurement systems. Frequency/level setting times are already shorter than 2 ms/1.5 ms in normal operation.
All-purpose instrument The signal generator has a lower f requency limit of 9 kHz, which makes it suitable for use in EMC applications. The upper frequency limit is 3 GHz or 6 GHz. Amplitude and pulse modulation are provided as standard; frequency and phase modulation with a bandwidth of 10 MHz can be implemented optionally (R&S®SMA-B20/R&S®SMA-B22).
The RF signal can be internally m odulated by means of the built-in LF generator or the optional multifunction generator (R&S®SMA-K24). The multifunction generator supplies various waveforms including sine wave, square wave, user-programmable trapezoidal waveforms or noise with selectable bandwidth. Modulation signals can be added together, with different weighting applied to the individual signals. The modulation signals for AM/FM/φM and for the LF output can be set independently of one another.
Aerospace and defense applications For pulse modulation, the R&S®SMA100A includes as standard a high-quality pulse modulator with an on/off ratio of > 80 dB and a rise/fall time of typ. 7 ns as well as a basic pulse generator. Optionally, a high-performance pulse generator with a minimum pulse width of 10 ns, a resolution of 5 ns and a variety of setting options is available (R&S®SMA-K23).
The R&S®SMA100A offers internal (linear) chirp generation up to an 80 MHz chirp bandwidth without the need for external synchronization. Frequency and pulse modulation are synchronized internally. This feature can be used in radar applications, for example. When equipped with the R&S®SMA-K25 option, the R&S®SMA100A can generate avionics signals (VOR/ILS) in accordance with ICAO standards.
If the R&S®SMA100A signal generator is equipped with the R&S®SMA-K28 power analysis option, the DME double pulse parameters can be simply displayed and automatically measured. This eliminates the need for other measurement equipment such as oscilloscopes and RF detectors. The application note “Test of DME Transponders” (1GP74) can be downloaded from the Rohde & Schwarz website (Application Notes download area).
Intuitive operating concept and versatile interfaces Intuitive operating concept The signal flow is shown by a s traightforward block diagram on the R&S®SMA100A color display (480 × 272 pixel). Thus, the user can immediately see the activated and deactivated generator blocks as well as where settings can be made. The entire operating manual for the R&S®SMA100A signal generator is integrated into the instrument’s help system.
Selectable control language In addition to the standard SCPI remote-control command set, the R&S®SMA100A offers emulations of common analog signal generators. If these generators are no longer manufactured or if they can no longer be repaired, the user can easily replace them with the R&S®SMA100A. This eliminates the time- and budget-consuming task of rewriting the remote-control software. Selection of GPIB command set. Rear view of the R&S®SMA100A and its versatile interfaces.
