Content is AI-generated. Verify critical details with manufacturer-provided resources.
The Rohde & Schwarz SMA100B with option B103 is a premium RF signal generator covering a frequency range of 8 kHz to 3 GHz. It is designed to deliver the purest CW signals with outstanding spectral purity, very low harmonic and nonharmonic signal components, and exceptionally high output power. The B103 option uses an electronic step attenuator and is available in flexible 2 HU or 3 HU housing configurations.
The SMA100B B103 operates from 8 kHz to 3 GHz with a frequency setting resolution of 0.001 Hz and a synthesis resolution of 0.053 nHz at 1 GHz. The frequency setting time is less than 2.0 ms after an IEC/IEEE bus delimiter, making it suitable for fast automated test sequences. It also supports phase-continuous frequency steps up to 0.02% of the set frequency.
The SMA100B B103 achieves excellent SSB phase noise of less than -135 dBc (typically -140 dBc) at 1 GHz with a 20 kHz offset, and less than -125 dBc (typically -130 dBc) at 3 GHz. At 100 MHz, the phase noise improves to less than -154 dBc (typically -159 dBc). These specifications make it one of the purest signal sources available for sub-3 GHz applications.
In the standard configuration, the SMA100B B103 offers a specified output level up to +19 dBm from 1 MHz to 3 GHz. With the R&S SMAB-K31 high output power option, this extends to +25 dBm. With the R&S SMAB-B32 ultra high output power option, the output reaches up to +30 dBm from 8 MHz to 3 GHz, supporting demanding high-power test applications.
The SMA100B B103 achieves harmonic suppression better than -60 dBc above 10 MHz at 10 dBm output level, and better than -30 dBc from 100 kHz to 10 MHz. Nonharmonic spurious signals are less than -96 dBc below 750 MHz, less than -92 dBc from 750 MHz to 1.5 GHz, and less than -86 dBc from 1.5 GHz to 3 GHz. The wideband noise floor is less than -155 dBc from 8 MHz to 1.5 GHz.
The SMA100B B103 supports AM (with the R&S SMAB-K720 option), FM, phase modulation, and pulse modulation (with the R&S SMAB-K22 option). FM offers high bandwidth and low noise modes with a maximum deviation of N x 10 MHz in high bandwidth mode. Pulse modulation provides an on/off ratio greater than 80 dB with rise/fall times less than 10 ns and a minimum pulse width under 20 ns.
The 3 GHz SMA100B B103 is ideal for applications requiring exceptionally pure CW signals in the sub-3 GHz range, such as receiver blocking and selectivity testing, local oscillator substitution, component testing, and VOR/ILS navigation aid simulation with the optional R&S SMAB-K25 option. Its excellent level accuracy (less than 0.5 dB from 8 MHz to 3 GHz) and high output power make it well-suited for semiconductor and amplifier characterization.
Yes, the SMA100B B103 includes the R&S LegacyPro feature, which allows it to emulate several other signal generators including the R&S SMA100A, R&S SMF100A, Keysight PSG, and Keysight MXG. This enables plug-and-play replacement in existing automated test systems without requiring changes to the test software, which is particularly convenient when renting the instrument as a temporary substitute.
