R&S SMB100A Signal Generator
Version 01.01, July 2007
Key features
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 downconverter)
• Nonharmonics 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
1
Verification of level accuracy and automatic level correction with a connected power sensor of the R&S NRP family
… 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

Level
®
The R&S SMB100A has two different attenuator modes for level setting:
AUTO MODE: In this mode, the attenuator is switched automatically. The output level is specified over the full range from –120 dBm
to +13/18 dBm.
FIXED MODE: The level is set without switching the attenuator. The attenuator is fixed to the current setting. If ALC state is ON, level
changes are performed without interruption. The maximum attenuation range is limited. With higher attenuation, the spectral purity of
the output signal decreases.

Pulse modulation (R&S®SMB-K22 option)
®
When pulse modulation is activated, the ALC state of the R&S SMB100A is automatically changed to ALC OFF (Sample & Hold). In
this state, the ALC loop is opened and the output level is set directly. In order to set the correct output level, a sample & hold
measurement is performed after each frequency or level setting.
