SP1212 Digital Synthetic Audio Sweep Signal GeneratorDetailed product description：

The SP1212B series of digital synthesized audio sweep signal generators adopts DDS digital direct synthesis technology, controlled by AVR high-speed microcontroller, LED display, button operation, and has safety functions such as startup delay output, short circuit current limiting protection, and output amplitude protection. Easy to operate and more user-friendly, it is an ideal upgraded alternative to traditional audio signal sources.

Key Features:
Adopting Direct Digital Synthesis (DDS) technology

The starting and ending frequencies of scanning can be set separately and arbitrarily
High reliability: MTBF>10000h
The small signal output amplitude reaches 10 mVrms.
The chassis has a beautiful and elegant design, and the button operation is comfortable and flexible.
