Description:

The AD9833 is a programmable waveform generator capable of generating sine, triangle, and square wave signals at frequencies from 0 to 12.5MHz. The waveform generator is widely used in various measurements, excitations, and determining time domain fields. Output frequency and phase can be set via software, which is easy to operate. When the main clock frequency is 25MHz, the accuracy is 0.1Hz, and when the main clock frequency is 1MHz, the accuracy can reach 0.004Hz. Data can be written via 3 serial interfaces.

Uses:

• Frequency excitation / waveform generation. Measurement of fluid and air flow.
• Sensitive usage - access, motion, fault detection.
• Linear loss, linear attenuation.
• Testing equipment and other devices.
• Scanning, clock generator.
