Measure Currents in a Wide Range of Applications
Measuring AC and
DC Currents
LeCroy current probes do not
require the breaking of a circuit
or the insertion of a shunt to
make accurate and reliable current
measurements. Based on a combi-
nation of Hall effect and transformer
technology, LeCroy current probes
are ideal for making accurate AC, DC,
and impulse current measurements.
Fully Integrated with
Oscilloscope
Many current probes require external
power supplies or amplifiers to display
a waveform on the oscilloscope
screen. All LeCroy current probes
are powered through the LeCroy
ProBus®connection and require
no additional hardware. Along
with providing power, the ProBus
connection allows the current probe
and oscilloscope to communicate,
resulting in current waveforms
automatically displayed on screen
in Amps, and calculated power traces
scaled correctly in Watts. This full
integration also allows for Degauss
and Autozero functions to be done
directly from the oscilloscope with
a single button press.
Applications
LeCroy current probes are available
in a wide range of models for a
wide range of applications. The
full range of LeCroy current probes
includes models with bandwidths
up to 100 MHz, peak currents up to
700 A and sensitivities to 10 mA/div.
Multiple current probes can be used
together to make measurements
on three-phase systems, or a single
current probe can be used with a
voltage probe to make accurate
instantaneous power measurements.
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.

DA1855A – Differential Amplifier
The DA1855A high-performance
differential amplifier provides
100 MHz bandwidth, industry
leading overdrive recovery, and
outstanding common mode rejection ratio. The fast overdrive
recovery provides the ability to make critical saturation voltage
measurements while the high CMRR enables upper gate drive
measurements. Built into the DA1855A is a precision voltage
generator for offset far greater than the oscilloscope can provide
on its own. The DA1855A can be operated in true differential
mode or switched to comparator mode.
DCS015 – Deskew Calibration Source
To make accurate instantaneous power
measurements it is critical that both
the current and voltage waveforms be
aligned in time. The DCS015 calibration
source has both voltage and current time-aligned signals, which
enables the precise deskew of voltage and current probes. Most
voltage probes along with the AP015, CP015, CP030, and CP031
are compatible with the DCS015.
ADP300 and ADP305 –
Active Differential Probes
The ADP300 and ADP305 are high-voltage
differential probes ideal for measuring
power electronics. The 20 MHz bandwidth
ADP300 is good for troubleshooting low
frequency power devices and other circuits
where the reference potential is elevated
from the ground or the ground is unknown. The 100 MHz
bandwidth ADP305 is designed for measuring the floating
voltages found in today’s high-speed power electronics.
PMA2 – Power Measurement
Analysis Software
The PMA2 software option is used to
make critical power switching device
measurements, perform control loop
modulation analysis, and measure
power harmonics. With PMA2, the
display and setup of voltage waveforms, current waveforms,
and necessary measurement parameters are done automatically.
Important device measurements like power losses, saturation
voltage dynamic-on resistance, and safe operating area are easily
performed. Pre-compliance testing to EN 61000-3-2 with easy-to
-read graphical and tabular pass/fail results is built in to PMA2.
