Introduction
The 60 V Common Mode Differential Probes (DLxx-HCM) offer 60 V of common mode and
80 V differential input range with 1 GHz of bandwidth, making them the ideal probe for
lower voltage GaN power conversion measurements.
The Common Mode Rejection Ratio (CMRR) for the probes is exceptional to very high
frequencies. This provides for the best measurement performance when measuring very
fast slew rate (high dV/dt) PWM signals typical of GaN devices and systems. Exceptional
CMRR, combined with low probe noise and high offset capability, makes the probes
capable of measuring very small control signals floating on high common mode voltages.
The DLxx-HCM probes are calibrated for high-precision measurements to within 0.5% at DC
and 0.1 dB flatness from DC to 100 MHz. This ensures high accuracy top and base voltage
level measurement of pulse-width modulated signals. The Precision Gain Calibration
capability furthers measurement precision by improving the gain accuracy and removing
small offset drifts from the measurement configuration.
Equipped with a wide variety of standard tips, the 60 V Common Mode Differential Probes
provide the perfect combination of high performance and flexibility for connecting to any
device under test. An optional accessory kit and high temperature solder-in tip are available
for further connectivity options.
Compatibility
DL05-HCM and DL10-HCM are compatible with Teledyne LeCroy oscilloscopes equipped
with the ProBus interface running Windows® 10 Pro or Windows CE operating systems.
See our website for all compatible oscilloscope models.
Required Firmware
Proper functioning of the probes requires a minimum version of MAUI™ firmware 9.3.x.x to
be installed on the oscilloscope.

Standard Accessories
The probes are delivered with the following standard accessories.
Item
Description
QTY
Browser Tip
The browser tip attaches to the amplifier for hand-held browsing. It
combines high performance with quick access to a variety of probing
points.
1
2” Solder-in Tip
This lead can be soldered directly to the test points for a secure probe
connection. Two-inch long leads give more flexibility in connecting to
hard-to-reach test points.
1
High Performance
Solder-in Tip
Because of their small size, these tips provide the maximum signal
fidelity at the highest frequency response. They are soldered to the test
points like the 2” solder-in tips.
2
2” Y-lead Socket
Y-lead sockets are used to probe differential signals that are far apart on
the board. They can be connected directly over pins, used with single
pins inserted, or with grabbers attached to connect to very tightly
spaced points.
1
5” Y-lead Socket
Same as above with five-inch long leads. This Y-lead could be used to
extend into spaces where it is difficult to place the amplifier.
1
Mini-Grabbers
Mini-grabbers can be used to connect to very tightly spaced pins. They
are always attached to a Y-lead socket.
3
Straight Pin Header
The straight-pin header is used to connect to female receptacles. It is a
fixed spacing of 2.54 mm (0.1 inch).
2
Single Pin
The single pin fits into either socket of the Y-leads or the ground lead to
make contact where there is not a pin on the board.
6
Ground Lead
The bendable, socket-tipped ground lead can be used alone, or with the
single pin or grabbers inserted for probing ground planes.

High Temperature Lead
The “Hi-Temp” lead can be used in controlled
situations where the differential amplifier
needs to be removed from an extreme
temperature environment. Ideally suited for
testing where the temperature can fluctuate
from -40 °C to +125 °C, the 1-meter long lead
provides an easy and robust connection to the
circuit under test. It is designed to be soldered
to the test board like the solder-in tips.
DL-HCM-Hi-Temp

Deskew Fixture
The PCF-200 deskew fixture may be used to
determine the effect of probe input loading on
the DUT, for verification of the probe’s
response to the signal being measured, or as a
convenient way to deskew probes or
oscilloscope channels.
PCF-200

DL-HCM Accessory Kit
Includes the following items.
DL-HCM-Acc-Kit
Freehand Probe Holder
The Freehand probe holder is designed to keep
weight on the probe tip while securing the
position of the amplifier. It helps prevent loss
of contact when the circuit under test is
destabilized. The amplifier can be mounted
horizontally or vertically in the Freehand.

Y-banana Adaptor
The Y-banana adaptor is used to connect
banana tips delivered with other probe models
to the DLxx-HCM probe.
1
Micro-Grabbers
Micro-grabbers are ideal for connecting to
small IC legs or very tightly spaced pins. It is
always used with a Y-lead.
