Embedded serial bus analysis

Serial bus decode and trigger options transform the 4 Series MSO into an indispensable tool for debugging serial buses with automatic decode, trigger, and search. Here are a few examples:

  • I2C, SPI
  • I3C
  • RS-232 / 422 / 485 / UART
  • USB 2.0
  • Ethernet

See the datasheet for all supported buses.

 
SPI BUS
MSO 4 Series Power Rail

Power integrity and power management

Today’s boards can have 20 or more power rails, many of which are less than a few volts with strict noise limits.

  • Up to 6 analog input channels
  • Compatible low-noise power-rail probes
  • Decoding options for SVID and SPMI

Power supply measurements and analysis

Even with lower standby power, faster switching and stricter noise limits, the 4 Series can speed up power supply troubleshooting, optimization and validation.

  • AC line and harmonics measurements
  • Switching loss analysis
  • DC power rails measurements
  • Bode plots and power supply rejection ratio
  • Wide range of current, power rail, differential, and optically-isolated probes
MSO 4 Series Power Application
Automotive ECU design

Automotive ECU design

Automotive systems demand robust communications between ECUs, sensors and actuators.

  • Mixed signal views to look beyond processors at sensors, actuators, switches, and power
  • Combine waveform and spectrum analysis for fast noise hunting with optional Spectrum View
  • Decode and trigger on CAN, CAN FD, LIN, FlexRay, SENT or PSI5 traffic
 

Learn about CAN, CAN FD, LIN and FlexRay decoding and triggering speed debug

Learn about SENT bus decoding and triggering

Electromagnetic interference (EMI) troubleshooting

With the Spectrum View option each analog channel on the 4 Series MSO can show you a time domain waveform, a spectrum, or both. The time and frequency plots are synchronized to help you quickly determine which signals are the victims and which ones are the aggressors.
