 ◈ Modulation types : AM, FM, φM, Pulse and I/Q 
 ◈ NF output : 20 Hz to 80 kHz 
 ◈ Phase noise : <-95 dBc (1 Hz) at 20 kHz offset 
 ◈ Level uncertainty : < 1dB (at levels >-120 dBm)  
 ◈ Graphical oriented user interface 
 ◈ USB interface  
 ◈ The Signal Generator R&S SM300 offers all the features
    required of a general purpose signal generator: wide
    frequency range, large variety of modulation functions and 
    high reliability at an extremely attractive price. 

     The fields of application of the R&S SM300 are virtually unlimited
     in development, servicing or production where it is used as a
     flexible signal source in automatic test systems.
     The built-in I/Q modulator is ideal for generating digitally
     modulated signals. An external two-channel arbitrary waveform
     generator (e.g. R&S AMIQ) serves as a modulation source.
