Teledyne LeCroy Capability

Typical Oscilloscope Capability

Typical Power Analyzer Capability

Teledyne LeCroy combines the best of everything into a single instrument for complete test coverage with 12-bit resolution all the time and integrated 3-phase electrical and mechanical power calculations.

Up to 16 analog channels (16 digital optional) – acquire more, learn more
Capture control, sensor and power signals simultaneously, correlate problems quicker
Everything in one instrument, on one display with helpful dynamic power views

Usually limited to 8-bit resolution – insufficient for accurate power calculations. Or advertised resolution is only at reduced bandwidth and sample rates – insufficient for control analysis.

8-bit resolution limits power calculation accuracy to ~5%
Limited channels for 3-phase power system debug
Primarily used for control system debug only

A power analyzer instrument is a specialized, single-purpose tool that can only capture low-speed power waveforms for very short periods of time with no dynamic power analysis capabilities

Static power analysis only
No control debug capability
Low speed, low sample rate (5 MHz bandwidth, 2 MS/s typical)

Webinar Series – 3-phase Power and Motors Masters

This series concentrates on measuring high power, three-phase and motor inverter and drive systems with an 8-channel high-resolution oscilloscope or motor drive analyzer. Learn about static and dynamic measurements, from AC line to inverter switching to drive outputs to motor mechanical output power.

Part 1 - How to Measure Inverter Dead Times and Input/Output Power

We describe techniques for measuring dead-times for gate-drive signals and device outputs to ensure that margins are achieved. We also assess input and output power of a simplified single-phase DC-AC inverter.

Part 2 – How to Perform Static and Dynamic Power Analysis

We describe the differences between static and dynamic power analysis and how to optimize setup and measurement for each. Special attention will be paid to visualizing dynamic power trends and correlation of these trends back to acquired voltage and current waveforms.

Part 3 – How to Correlate Control Events to Power Events

We review examples of using calculated per-cycle power waveforms to validate and debug control system operation to power section behaviors.

Part 4 – How to Measure Power During Volt-second and Other Short Power Periods

We review examples of power calculated during power periods equivalent to a device switching time. This is especially helpful for understanding instantaneous control response time, as required for deadbeat-direct torque and flux control

Part 5 – How to Perform AC Input and Inverter/Drive Output Harmonic Analysis

We demonstrate how to perform total harmonic distortion (THD) and harmonic analysis on variable frequency waveforms on both AC line (50 or 60 Hz) inputs and variable frequency outputs.

Part 6 – How to Measure Motor Mechanical Speed, Torque and Power

We focus on how to use the Motor Drive Analyzer to measure motor mechanical shaft speed, torque, and angle using a variety of analog, digital, and serial data sensors.

Probing in Power Electronics – What to Use and Why?

Power electronics designs have inherent measurement challenges. There are many specialized high and low voltage single-ended and differential probes to meet the specific needs of this market. However, proper probe selection and use is critical for operator, equipment and DUT safety and also has a large influence on the accuracy of the measurement.

Part 1 - How to Choose the Correct High Voltage Probe

In this webinar we discuss how to choose the correct high voltage probe, taking into consideration the application and the safety of the operator, equipment, and DUT. The difference between the “right” probe and the “wrong” probe is usually not black and white, but more of a shade of gray.

Part 2 – High Voltage Probe Real-world Examples and Comparisons

In this webinar we provide many real-world application examples and probe comparisons to highlight the practical impact of each high voltage probe type’s strengths and weaknesses in different application examples.

Essential Principles of Power: Voltage, Current and Power – from AC Line to PWM

Learn about the AC utility supply voltages and ratings, and what is meant by Volts, Amps, RMS, true RMS, Watts, VAs, VARs, power factor and phase angle, delta and wye three-phase electrical systems, and the measurement challenges.

Measuring Motor Performance: Using Power Analyzers and Oscilloscopes

In this webinar we will discuss the measurement challenges in debugging a complete motor drive embedded control and power system.

Power Conversion Fundamentals – from Semiconductor Devices to Complex Drives
