Embedded serial bus analysis, embedded design and IoT

The 3 Series MDO helps you overcome system level challenges with automatic trigger, decode, and search options for serial buses. Options are available individually or as a cost-effective bundle. Discover and solve issues quickly by performing system level debug on mixed signal embedded systems including today's most common serial bus technologies with the 3 Series MDO and support for a broad set of common serial buses.

Power measurements, analysis and power design

The 3 Series offers power test solutions to help get fast answers in today’s world of higher switching speeds and stricter noise limits.

Make reliable and repeatable voltage, current, and power measurements using automated power quality, switching loss, harmonics, ripple, modulation, and safe operating area measurements with the widest selection of power probes in an affordable solution.

Electromagnetic interference (EMI) troubleshooting

Not getting to the root cause of EMI failures can prevent you from shipping product. The 3 Series MDO with its built-in spectrum analyzer can help you sniff out sources of EMI fast.

Engineering education

Go beyond AC and DC theory to cover mixed signal designs with logic channels and built-in spectrum analyzer. Managing multiple instruments on a bench can be troublesome. The 3 Series MDO combines analog, digital, and RF measurements with a signal source in a single, small (5.9 in., 149 mm deep) instrument. The combination of a small instrument and high level of integration aids in the teaching of various electronics principles as well as in its usage for more sophisticated lab experiments. Full upgradeability enables adding functionality over time as needs change or budgets allow.

Manufacturing Test and Troubleshooting

Size and space constraints can play havoc on a manufacturing floor. The 3 Series MDO minimizes rack or bench space by integrating multiple instruments into one small package. Integration reduces cost associated with utilizing multiple different instrument types in manufacturing test or troubleshooting stations.

Service Installation and Maintenance

Having the right instruments when and where you need them is critical. The 3 Series MDO combines analog waveforms, digital logic, and spectrum analysis in a lightweight (11.7 lbs, 5.3 kg), portable package -making it the perfect choice where space is limited and flexibility is desired.
