DDSPA Direct Digital Synthesizers

Description

Direct Digital Synthesizers models offer high frequency accuracy and stability and extremely fast switching times less than 100ns. They will be preferred to VCOs when high stability and accuracy is necessary. They can be modulated (amplitude) from an analog or digital external signal. The frequency is externally controlled by a digital signal (15 to 31 bits). An external power amplifier will be required to generate the RF power levels required by the AO device.

PHASE LOCKED Versions with 2 inputs (option) : DDS outputs with common Reference for high stability frequency difference
