General Information -
The DST501 generates modulated arbitrary frequency CW signals from two DDS chips with frequency update rates of up to 1/8 of the DDS input clock rate. Modulated signals can be upper-sideband suppressed, lower-sideband suppressed or neither. The on-board SRAM provides 450K 24-bit data memory. The DST501 can be controlled by a PC or can work alone with pre-stored chirping waveform.
Key Features:
- 11-bit amplitude and 13-bit phase resolution ROM
- Carrier frequency ranges from 4 to 7 GHz
- Baseband input clock rate up to 2.5 GHz for arbitrary chirping
- 450K 24-bit words memory depth
- Multiple waveform generation modes including Free Run, Triggered Free Run and Triggered Burst modes
- Minimum waveform lengths of 256 ns in Triggered Burst Mode
- Accepts external LVTTL/LVCMOS trigger
- Generates LVTTL/LVCMOS marker signal (programmable)
- USB 2.0 compliant interface
- 17 W power consumption (at 1.0 GHz clock)
- User-friendly input data formats and various built-in chirping waveforms
- Companion API and software drivers for easy system development
