General Information -
The DSM303 module generates arbitrary frequency chirping CW with frequency update rates up to 312.5 update/microsecond (1/8 of the clock rate). The on-board SRAM provides 450K 32-bit data memory. The DSM303 can be controlled by a PC or can work alone with pre-stored chirping waveform. The sole RF input is the clock source DDSCK at 2.5 GHz with minimum power of 0 dBm. The outputs of the module consist of a pair of differential analog outputs, DDSOP/DDSON.
