190 Series III
Users Manual
The MDA-550-III Motor Drive Analyzer is an extension of the ScopeMeter
III with additional functionality and accessories that test inverter type motor drives. Inverter type
motor drives are known as variable frequency drives or variable speed drives and use pulse
width modulation to control ac motor speed and torque. The test tool supports motor drives with
signal levels up to 1000 V to ground.
For Motor Drive Analysis, the test tool provides:
• Key motor drive parameters
Includes measurement of voltage, current, dc link voltage level and ac ripple, voltage and
current unbalance, harmonics, and voltage modulation.
• Extended harmonics
Identifies the effects of low and high order harmonics on the electrical power system.
• Guided measurements
Guidance for motor drive input, dc bus, drive output, motor input, and shaft measurements.
• Simplified measurement setup
Graphically shows how to connect and then automatically triggers according to the selected
test procedure.
• Reports
Use for troubleshooting and collaborative work with others.
• Additional electrical parameters
Full 500 MHz oscilloscope capability is available for the complete range of electrical and
electronic measurement on industrial systems.
The TrendPlot function in the Recorder mode plots a graph of selected Motor Drive readings over
time.

The Motor Drive Analyzer is based on the ScopeMeter test tool model 190-504. All references to
models 190-xx2 can be ignored.
The accessory set that is included for the Motor Drive Analyzer is different than the ScopeMeter
Test Tool 190 Series III. See
