The BK Precision 2190E is a 100 MHz two-channel digital storage oscilloscope designed to combine performance and value in a portable bench instrument. With a 1 GSa/s single-channel real-time sampling rate, record lengths up to 40,000 points, and a 7-inch 800x480 TFT color display, the 2190E offers a significantly larger viewing area than typical economy oscilloscopes in the 5.7-inch class.

Per the datasheet, the 2190E is positioned for applications in education, design and debug, and service and repair. A dedicated EDU mode allows educators to disable the Auto setup button, Measure menu, and Cursors menu — useful for instructional environments where students must work through measurements manually. The instrument supports 12 different user-interface languages and includes context-sensitive help.

## Brand Heritage

BK Precision was founded in Chicago in 1951 and has operated for over seven decades as a manufacturer of test and measurement instruments for education, service, and engineering applications. The company is headquartered in Yorba Linda, California and remains an active T&M brand under its original name.
