In this demonstration we compare Analog IQ modulation to Digital IQ modulation. Advances in DAC technology now means that many chips support direct to RF capability, with built in Oscillators (Numerically Controlled) and IQ modulation capability. The new Proteus Arbitrary Waveform Generator from Tabor has this capability with a usable bandwidth up to 8GHz supported by multiple Nyquist zone operation. The tasks of balancing and nulling are no longer required using this approach, thus reducing setup time and maintenance of complex calibration tables and procedures.
