R&S^®SMA100A Signal Generator

The R&S^®SMA100A combines superior signal quality with very high setting speed, which makes it ideal for any task. Whether in development, production, service or maintenance, the R&S^®SMA100A does an excellent job.

In the frequency range from 9 kHz to 6 GHz, it can generate CW signals as well as all common types of analog modulation (AM, FM, φM, pulse modulation). Excellent specifications and a wide range of modulation signals – these are the characteristic features of the R&S^®SMA100A. In addition, a low-jitter clock synthesizer option supplies differential clock signals of up to 1.5 GHz independently of the RF frequency.

Excellent signal quality

• Very low SSB phase noise of typ. –135 dBc (20 kHz carrier offset, f = 1 GHz, 1 Hz measurement bandwidth), typ. –140 dBc with the Enhanced Phase Noise Performance option (R&S^®SMA-B22)
• Wideband noise of typ. –160 dBc (>10 MHz carrier offset, f = 1 GHz, 1 Hz measurement bandwidth)
• Nonharmonics of typ. –100 dBc (>10 kHz carrier offset, f < 1500 MHz, with the R&S^®SMA-B22 option)

Ideal for use in production

• Very short frequency / level setting times of typ. 1.3 ms/1ms across the entire frequency and level range, <450 μs in LIST mode
• Fast hopping mode with flexibly addressable frequency and level pairs, as fast as normal LIST mode
• Frequency setting time of nominal 10 μs within a bandwidth of 80 MHz due to direct access to the DDS-based synthesizer (with the R&S^®SMA-B20 or R&S^®SMA-B22 option; FM EXTERNAL DIGITAL mode)
• Electronic attenuator with built-in overvoltage protection over entire frequency range
• High output power of up to +18 dBm, overrange +28 dBm
• Very high level accuracy and repeatability

Mil/Aero applications

• Optional operating altitude up to 4600 m (R&S^®SMA-B46)
• Optional removable mass storage (compact flash disk, R&S^®SMA-B80)

All-purpose instrument

• Frequency range of 9 kHz to 3 GHz (R&S^®SMA-B103/R&S^®SMA-B103L) or 6 GHz (R&S^®SMA-B106/R&S^®SMA-B106L)
• Frequency, level and LF sweeps
• AM, broadband FM/φM (R&S^®SMA-B20 or R&S^®SMA-B22), pulse modulation
• Built-in LF generator up to 1 MHz, optional multifunction generator (R&S^®SMA-K24) up to 10 MHz
