Bedrock SBxx advanced USB controlled acoustic analyzer

The Bedrock SB41 (class 1) and SB42 (class 2) are full-featured acoustic measuring instruments that serve as a front-end within a variety of computer-controlled measuring setups. With a minimalistic, no-screen, no-battery design, the SBxx is ideal for automated, unsupervised measurements via our Remote Control API. Alternatively, a remote display can be streamed over USB to your host device as well. This gives you the power and reliability of a class 1 or class 2 instrument, combined with full integration flexibility for your own software.
