DCS025

Teledyne LeCroy current probes are available in a variety of models for a wide range of applications. The full range of Teledyne LeCroy current probes includes models with bandwidths up to 100 MHz, peak currents up to 700 A and sensitivities to 1 mA/div. Teledyne LeCroy current probes are often used in applications such as the design and test of switching power supplies, motor drives, electric vehicles, and uninterruptible power supplies.

• DCS025 - Deskew Calibration Source for Teledyne LeCroy current probes

The CA10 is a programmable and customizable interface device that seamlessly incorporates third party current transducers/transformers with Teledyne LeCroy oscilloscopes or motor drive analyzers. The easy to use interface provides the ability for the CA10 to be programmed to contain the specifications of the current sensor allowing it to automatically correct for the gain or attenuation and display results in Ampere units. This allows the third party device to be recognized and operate as if it were a Teledyne LeCroy probe.

• CA10 - Programmable ProBus Current Sensor Adapter for use with third party current sensors

The DCS025 Deskew Calibration Source generates time-aligned voltage and current pulses for precise deskew of voltage and current probes.This is critical for measurements in which small propagation delay differences between probes can have a large impact on a calculated measurement, e.g., instantaneous power semiconductor device loss measurements.

• 10 ns signal fall time
• Only 1 ns static skew
• 5 V and 100 mA time-aligned output signals
• Loop size compatible with 30, 150 and 500 Amp current probes
• Compatible with standard and high-sensitivity current probes

A voltage probe connects to the voltage pulse signal and ground connection and a current probe connects around the current pulse loop. Propagation delay differences between the two probes are then measured and manually deskewed by the operator using the Deskew adjustment in the oscilloscope’s Channel setup dialog.

The DCS025 has a large current loop that is compatible with Teledyne LeCroy small (e.g., CP03x) and large sized current probes (e.g., CP150, CP500). Channel acquisition averaging permits measurement of the output current amplitude with higher amperage current probes.

The internal static skew of the DCS025 is only 1 ns – well-matched to the rise times of the DCS025 and the probes commonly used for power semiconductor device loss measurements.

The DCS025 connects to the EXT input of the oscilloscope and outputs a trigger signal to simplify time alignment and deskew operations to the signal fall time at the center of the oscilloscope display.
