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.

Probe Components

The 60 V Common Mode Differential Probes consist of an amplifier and a selection of

standard leads and tips. Optional accessories are available for purchase separately.

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.

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.

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” 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.

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.

Mini-Grabbers

Mini-grabbers can be used to connect to very tightly spaced pins. They

are always attached to a Y-lead socket.

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).

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.

Ground Lead

The bendable, socket-tipped ground lead can be used alone, or with the

single pin or grabbers inserted for probing ground planes.

Storage Case

Soft storage case.

Accessory Tray

Plastic insert for storage case.

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.

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.
