4 Series MSO Mixed Signal Oscilloscope

Biggest display in its class and award-winning user interface

With the same made-for-touch user interface technology as the award-winning 5 Series and the largest and highest resolution display in its class, the 4 Series MSO sets a new expectation of how a scope should work.

• 13.3-inch HD display
• 6.1-inch (15.5 cm) deep bench-friendly footprint

Industry-Leading Probes

Accurate measurements start with great probes. Every 4 Series comes with the best passive probes in the industry, with loading of just 3.9 pF and up to 1 GHz bandwidth. The TPP Series probes will be your go-to probes for everyday use.

Highlights

• TPP Series probes included standard. One per analog channel.
• Industry-best capacitive probe loading of 3.9 pF
• 250 MHz, 500 MHz or 1 GHz probe bandwidth depending on instrument bandwidth

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

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.
