DCS025
Deskew Calibration
Source
Key Features
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 500A current probes
Compatible with standard and
high-sensitivity current probes
Simple to Use
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.
Large Current Loop
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.
Low Static Skew
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.
Automatic Triggering Setup
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.
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.
