Description
Overview
GAOTek desktop USB digital storage oscilloscopes are super-economical types of digital storage oscilloscopes. The 2-channel oscilloscopes have a bandwidth of 200 MHz. They have ultra-thin bodies and are designed with 7 in (17.78 cm) high-resolution LCDs. They support SCPI and LabVIEW. They are used for electronic circuit debugging, circuit testing, design and manufacture, education and training, and automobile maintenance and testing.
