⭕ The 2700 Series is designed for audio engineers who need the highest performance, lowest distortion and greatest flexibility possible in their audio analyzer. With the Programmable Serial Interface Adapter (PSIA), it is the best solution for high end converter and other chip designers. The 2722s true dual domain architecture enables uncompromised measurement of both analog and digital signals: the analog generator and analyzer performance surpasses that of any digital converter-based design, while digital analysis techniques offer a wide array of precise, high-speed measurement techniques for either domain. Cross-domain work can be accomplished using the best of both worlds. 15 days return policy. Shipping/collection.
