Pulse Repetition Rate and Frequency Resolution

This paper covers important topics in s-parameter measurements made for signal integrity applications, where the time-domain implications are important. Recommendations are provided for deciding on two important settings for the WavePulser 40iX: TDR acquisition length - which is related to the pulser repetition rate. Number of frequency points - which is related to the end frequency and the required frequency resolution. Summary slides attached.

WavePulser 40 iX Second Tier Calibration

This paper discusses the three methods of calibration utilized in the WavePulser 40iX including the automatic internal calibration, manual calibration and second-tier calibration. Instructions are provided to perform manual and second-tier calibration, and how to factory calibrate the instrument. Summary slides attached.

SENT Basics: Verifying a Stable MTP for SENT SPC

This application note describes the SENT SPC protocol and demonstrates how to use a Teledyne LeCroy oscilloscope to verify a consistent Master Trigger Pulse (MTP) length.

Multiple Carrier Generation using T3AWG3K-series ARB and the Waveform Editor SW Utility

The T3AWG3k-series High-Definition (HD) Arbitrary Waveform Generator with the Waveform Editor SW Utility combined with the High-Definition (HD) Teledyne LeCroy Oscilloscopes provides a far superior insightful High Definition stimulus-response measurements set-up. The ability to generate a multiple carrier testing scenario with 16-bits vertical resolution (HD), Output Voltage swing up to ±12 Vpp (into 50Ω) and waveform memory up to 1 GPts. points can be an invaluable tool in troubleshooting complex signal transmission systems.

Volt-second Sensing Control Analysis in a DB-DTFC with the Motor Drive Analyzer

Deadbeat-direct torque and flux control (DB-DTFC) is being explored as an alternative to field-oriented controls (FOC) or direct torque control (DTC) due to its ability to achieve fast torque dynamics, manipulate losses without compromising torque, and utilize full DC bus voltage at voltage-limited operation. Evaluating the Volt-second sensing accuracy requires a precise measurement of Volt-seconds as the reference. Teledyne LeCroy's Motor Drive Analyzer provides such capabilities over each power-semiconductor switching period.
