Tektronix MSO44B Mixed Signal Oscilloscope

The Tektronix MSO44B is a four-channel mixed-signal oscilloscope designed for engineers and system integrators performing comprehensive signal analysis on complex electronic designs. It combines analog and digital measurement capabilities with an intuitive touchscreen interface, delivering real-time capture rates exceeding 500,000 waveforms/sec and vertical resolution up to 16 bits in High Res mode.

Technical Specifications

• Bandwidth: 200 MHz to 1.5 GHz, field-upgradable


• Sample Rate: Up to 6.25 GS/s real-time (analog and digital)


• Record Length: 31.25 Mpoints standard; upgradable to 62.5 Mpoints


• Vertical Resolution: 12-bit ADC, extending to 16-bit in High Res mode at ≤125 MS/s


• High Res Mode employs hardware-based FIR filtering to prevent aliasing while maintaining maximum bandwidth Physical & Display

• Weight: < 16.55 lbs (7.5 kg)


• Audible Noise: < 47 dB


• Requires 2.0 inches (50.8 mm) clearance on right and rear sides

Key Features FlexChannel Technology Each input adapts to analog, digital logic (with TLP058 probe), or combined analog/spectrum display. Scale to 32 optional digital channels via multiple TLP058 probes, or up to 48 total digital channels. Triggering & Search Edge, Pulse Width, Runt, Timeout, Window, Logic, Setup & Hold, and Visual Trigger modes with on-screen shape customization. Search capability across all trigger criteria. Analysis Waveform and V/H bar cursors, measurement histograms, FastFrame segmented memory for infrequent events, and Tektronix-patented Spectrum View for simultaneous analog and spectral analysis. RF measurements (CHP, ACPR, OBW) integrated. Optional protocol trigger, decode, and analysis for I2C, SPI, eSPI, I3C, RS-232/422/485/UART, SPMI, SMBus, CAN, CAN FD, CAN XL, LIN, and FlexRay.

Typical Applications Research and development, system validation, production testing, and complex circuit debugging requiring multi-domain signal analysis.

Compatibility & Integration TLP058 logic probes enable mixed-signal measurement expansion. Optional protocol modules support serial, automotive, and industrial communication standards.
