4 Series B MSO Mixed Signal Oscilloscope

The versatile 4 Series B MSO delivers the performance to tackle complex design challenges with an intuitive user interface that works the way you expect. With its newly upgraded processor system, this oscilloscope provides accurate measurements faster while featuring an excellent suite of analysis tools.

The 4 Series MSO offers 4-channel and 6-channel models along with a 13.3-inch high-definition (1,920 x 1,080) display for better visualization of complex systems. Many applications such as embedded systems, three-phase power electronics, automotive electronics, power supply design, and DC-to-DC power converters require observing more than 4 analog signals, verifying and characterizing device performance, and debugging challenging system issues.

Tektronix 4 Series B MSO Mixed Signal Oscilloscope Applications

Embedded Serial Bus Analysis

Serial bus decoding and triggering options transform the 4 Series MSO into an indispensable tool for debugging serial buses with automatic decoding, triggering, and search functions. Here are some examples:

• I2C, SPI

• I3C

• RS-232 / 422 / 485 / UART

• USB 2.0

• Ethernet

Power Integrity and Power Management

Today's circuit boards can have 20 or more power rails, many of which are only a few volts with strict noise limits.

• Up to 6 analog input channels

• Compatible low-noise power ripple probes

• SVID and SPMI decoding options

Power Measurement and Analysis

The 4 Series not only features lower standby power, faster switching speeds, and stricter noise limits, but also accelerates power troubleshooting, optimization, and verification.

• AC line and harmonic measurements

• Switching loss analysis

• DC power ripple measurements

• Bode plots and power supply rejection ratio

• Probes supporting various currents, power ripple, differential signals, and optical isolation

3-Phase Power Analysis

Stable three-phase power measurements can even be performed on PWM waveforms. The three-phase analysis package makes the task easy.

Features

• Up to 6 analog input channels

• Three-phase star, delta, and single-phase wiring configurations

• Comprehensive power measurements

• Harmonic analysis

Automotive ECU Design

Automotive systems require accurate communication between ECUs, sensors, and actuators.

• Mixed signal view, allowing engineers to look beyond sensors, actuators, switches, and power supplies

• Use the optional spectrum view to combine waveform and spectrum analysis for quick noise hunting

• Decode and trigger CAN, CAN FD, LIN, FlexRay, SENT, or PSI5 traffic

Remote Control and Automation

Achieve fast, repeatable results while allowing access to your data from anywhere. Learn about test automation resources, including our free Python driver package.

• TekScope PC software provides the same analysis capabilities as Tektronix oscilloscopes on your computer

• KickStart software simplifies data capture and recording. Supports function generators, power supplies, SMUs, and more

• Built-in *eScope or  remote desktop allows you to control the oscilloscope via any LAN

• Comprehensive and well-supported programmable interface aids in developing powerful custom software

Electromagnetic Interference (EMI) Troubleshooting

With the Spectrum View option, each analog channel on the 4 Series MSO can display time-domain waveforms, spectrum, or both. Time and frequency plots are synchronized, helping you quickly identify which signals are being interfered with and which are the sources of interference.
