Signal quality, speed and flexibility - these are the criteria by which signal generators are measured today. The R&S®SMA-B103 perfectly meets these criteria, and thus is a premium-class analog generator that sets standards due to its outstanding characteristics.
It combines superior signal quality with very high setting speed. Whether in development, production, service or maintenance, the R&S®SMA-B103 does an excellent job
Key Facts• Frequency options from 9 kHz to 3 GHz
• Very low SSB phase noise of typ. -141 dBc (at 1 GHz, 20 kHz offset, 1 Hz measurement bandwidth) with option
• Nonharmonics <-96 dBc (f < 750 MHz, carrier offset > 10 kHz) with option
• High output power of up to +18 dBm (+28 dBm in overrange)
• Emulation of legacy instruments
• Electronic attenuator with built-in overvoltage protection over entire frequency range
CharacteristicsIn the frequency range from 9 kHz to 3 GHz, R&S®SMA-B103 can generate CW signals as well as all common types of analog modulation (AM, FM, fM, pulse modulation). Excellent specifications and a wide range of modulation signals - these are the characteristic features of the R&S®SMA-B103.
In addition, a low-jitter clock synthesizer option supplies differential clock signals of up to 1.5 GHz independently of the RF frequency. This makes the R&S®SMA100A suitable for a variety of applications - from use in phase noise test systems through to tests on mixed-signal ICs.
The R&S®SMA-B103 signal generator also offers a modern graphical user interface for fast and intuitive operation.
The R&S®NRP-Zxx power sensors can be connected to the R&S®SMA-B103. The user can therefore perform very precise power measurements directly with the signal generator.
