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.
Key Features:
- 4 GSPS DDS with 11-bit amplitude and 13-bit phase resolution
- Output sampling rate up to 4 GSPS for chirping
- Standard output sampling rate at 4 GSPS
- Optional output sampling rate range from 1 to 4 GSPS in 200 MSPS increments
- 520K X 32-bit words memory depth with maximum 8 different user waveforms
- Waveforms can be switched dynamically by selecting user pages on the fly
- Minimum waveform length of 256 ns in Triggered Burst Mode
- Maximum 2 millisecond chirping waveform at 4 GSPS
- Programmable phase reset for phase repetition
- Accepts external trigger and generates marker signal (programmable)
- 14.6 W power consumption at 4 GSPS
- USB 2.0 compliant interface (USB cable included)
- Other interfaces available upon request
- Companion API and software drivers for easy system development
- API compatible with Matlab 2010a
- API compatible with LabView
