Tektronix MSO44B Mixed Signal Oscilloscope

Overview

The Tektronix 4 Series B MSO44B is an advanced 4-channel mixed signal oscilloscope engineered for debugging embedded systems, power converter analysis, and complex signal measurements. Featuring a significantly faster processor system compared to earlier models, the MSO44B delivers 2X more responsive controls and expedited data analysis. The instrument combines performance with versatile analysis capabilities, offering 4 FlexChannel inputs that can function as analog channels, digital logic inputs (with optional TLP058 probe), or provide simultaneous analog and spectrum views with independent controls. Each channel delivers full sample rate and record length simultaneously across all inputs.
