Rohde Schwarz SMB100A RF and Microwave Signal Generator
The Rohde Schwarz SMB100A is a compact versatile analog signal generator covering RF through microwave frequencies. It combines low phase noise, high output power, and a full set of analog modulations in just two height units which makes it a practical all purpose signal source for Rohde Schwarz production, and service. It can serve as a local oscillator a test signal source for receivers and components or an interferer in wireless testing.
Key Features
- Wide frequency coverage: 9 kHz to 12 GHz or 100 kHz up to 40 GHz depending on the frequency option fitted (12.75, 20, 31.8, or 40 GHz)
- Excellent spectral purity: low SSB phase noise of typically -128 dBc at 1 GHz and 20 kHz offset
- High output power: up to about +27 dBm typical on high power options which compensates for losses in cables, switches, and test fixtures
- Analog modulation: AM, FM/φM, and pulse modulation with an internal LF generator for modulation signals
- Optional pulse generator (SMB-K23): for radar and pulsed signal testing with fast pulse edges
- Compact and lightweight: just 2 height units suited to benchtop and rack mounted systems
- Easy operation: a clear front panel with display and a simple intuitive menu
- Remote control: LAN, USB, and GPIB interfaces for automated test systems
- Extendable range: combine with the R&S SMZ frequency multiplier for the 50 to 110 GHz range with adjustable output levels on most multipliers
- Low cost of ownership: broad functionality in a mid range space saving instrument
Typical Applications
- General purpose RF and microwave test source
- Receiver and amplifier characterization
- Local oscillator or clock source replacement in test setups
- Radar, satellite, and wireless component testing
- Production line and automated test systems
- Service, calibration, and teaching labs
Why Choose It
The Rohde Schwarz SMB100AÂ offers a strong balance of signal quality, output power, and size which means one generator can cover many tasks that would otherwise need several instruments. Its range of frequency options lets you buy the coverage you need today and its remote interfaces make it a good fit for automated test.
