Analysis of Embedded Serial Bus

The serial bus decoding and triggering options transform the 4-series MSO into an essential tool for debugging serial buses using automatic decoding, triggering, and search functions. Here are some examples:

Understand I²C and SPI bus decoding and triggering

Power integrity and power management

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

• Up to 6 analog input channels
• Compatible low-noise power ripple probe
• SVID and SPMI decoding options

Learn more information in the application instructions for power rail measurement

Power measurement and analysis

The 4 series not only has lower standby power, faster switching speed, and stricter noise limits, but also accelerates power troubleshooting, optimization, and verification.

• Communication line and harmonic measurement
• Analysis of switch losses
• Ripple measurement of DC power supply
• Baud plot and power suppression ratio
• Supports probes with various currents, power ripple, differential signals, and optical isolation

Understand the automatic measurement in power measurement and analysis through the application instructions of 4/5/6-PWR

3-phase power analysis

Even stable three-phase power measurement can be performed on pulse width modulation waveforms. The three-phase analysis program package can easily complete tasks.

Automotive ECU Design

The automotive system requires accurate communication between ECU, sensors, and actuators.

• Mixed signal view allows manufacturers to look beyond sensors, actuators, switches, and power supplies
• Use optional spectrum views, combined with waveform and spectrum analysis, to quickly perform noise search
• Decoding and triggering CAN, CAN FD, LIN, FlexRay, SENT, or PSI5 traffic

Understand CAN, CAN FD, LIN, and FlexRay decoding and trigger speed debugging

Understand SENT bus decoding and triggering

Remote control and automation

Get fast, reproducible results while allowing you to access your data from anywhere. Learn about testing automation resources, including our free Python driver package.

• TekScope PC software can provide the same analysis functions as TekScope oscilloscopes on your computer
• KickStart software simplifies data capture and recording. Support function generators, power supplies, SMUs, etc
• Built in eScope or Windows remote desktop allows you to control the oscilloscope through any LAN
• A comprehensive and fully supported programmable interface helps develop powerful custom software

Troubleshooting of Electromagnetic Interference (EMI)

Using the 'Spectrum View' option, each analog channel on the 4-series MSO can display time-domain waveforms, spectra, or both to you. Synchronization of time and frequency graphs helps you quickly determine which signals are being interfered with and which signals are the sources of interference.
