Best signal quality in its class

• Low SSB phase noise of typ. –128 dBc (20 kHz carrier offset, 1 GHz carrier frequency, 1 Hz measurement bandwidth)
• Very low SSB phase noise even at low output frequencies (because a new DDS synthesizer is used from 9 kHz to 23.4375 MHz instead of a down converter)
• Non-harmonics suppression of typ. –85 dBc (>10 kHz carrier offset, carrier frequency <1.5 GHz)
• Low wideband noise of typ. –152 dBc (>10 MHz carrier offset, 1 GHz carrier frequency, 1 Hz measurement bandwidth)
• Harmonics of typ. –30 dBc at the maximum specified output power of +18 dBm for high measurement accuracy in a wide variety of applications

Highest output power in its class

• Specified output power of +18 dBm over the wide frequency range of 1 MHz to 6 GHz
• Typical maximum level of +25 dBm (in overrange) over the entire frequency range up to 6 GHz provides power reserve to replace external amplifiers

On-site servicing as convenient alternative

• Flexible concept allows servicing to be done on site or by a Rohde & Schwarz service center
• Straightforward modular instrument design with only four exchangeable modules ensures short repair times
• Calibrated replacement modules make extensive calibration and adjustment tasks unnecessary
• Built-in selftest of modules supports troubleshooting
• Verification of level accuracy and automatic level correction with a connected power sensor of the R&S NRP family 1 ensures low cost of ownership and maximum instrument availability

All-purpose RF source

• Wide frequency range from 9 kHz to 6 GHz covers the main frequency bands for RF applications
• Integrated frequency, level, and LF sweeps
• All important analog modulations with AM, FM/φM, and pulse modulation supported
• Internal LF generator provides sinewave signals up to 1 MHz as well as squarewave signals up to 20 kHz
• Intuitive user interface with graphical display of the signal flow facilitates operation
• Context-sensitive online help ensures efficient utilization of the instrument makes the R&S SMB100A the ideal signal source for a wide variety of applications

Ideal for production

• Short switchover times for frequency of typ. 1.6 ms and level of typ. 1.2 ms via remote control and <1 ms in the List mode allow high throughput
• High level accuracy and repeatability are the basis of high production yield
• High output power of up to +25 dBm compensates level loss on the way to the DUT
• Wearfree electronic attenuator with overvoltage protection up to 6 GHz as standard ensures long service life even in the case of heavy use in production
• Compact design with only two height units saves rack space
• Remote control via LAN, USB, and GPIB allows easy integration into the test system reduces production costs

Ready for aerospace and defense applications

• Optional pulse modulator offers excellent performance with typ. 90 dB on/off ratio and a rise/fall time of typ. 10 ns
• Flexible pulse generator with minimum pulse width of 20 ns allows the generation of various pulse signals
• Wide temperature range of 0 °C to +55 °C and maximum permissible operating altitude of 4600 m above sea level allow the instrument to be used even under extreme conditions
• Low weight of only 5.3 kg for mobile applications expands the range of locations and applications for which the R&S SMB100A can be used
