Digital Synthesizer Module
DDS Based Arbitrary Chirping Module - DSM309

General Description:

The DSM309 module generates arbitrary frequency chirping CW with frequency update rates up to 312.5 updates/microsecond. At 4 GSPS, the module can generate frequency chirping in a bandwidth from DC to 2 GHz. The chirping profile can be linear or arbitrarily programmed. The DSM309 can be controlled by a PC via GUI or by user application programs via API, or can work alone with pre-stored chirping waveform. The chirping waveform generations can be in Continuous, Triggered Continuous or Triggered Burst modes. Up to 8 waveforms can be stored in user pages and pages can be switched on the fly.
