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)

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

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.
Setting range –145 dBm to +30 dBm

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.
