To date, most oscilloscopes with 50 Ω inputs terminate to ground by
the
50 Ω termination to a voltage rather than to ground. The Keysight
N7010A active termination adapter is a
30-GHz single-ended adapter
featuring a user-adjustable common termination voltage (VTERM) and
extremely low noise performance. The termination voltage between –
4.0 to +4.0 V can be controlled internally by the oscilloscope. The
N7010A is a single-ended adapter. Two scope channels and two
adapters are needed for making differential measurement, which allow
the A-to-GND, B-to-GND and differential (A-B) signals to be viewed in
real time
Utilizing low attenuation ratio setting (1.16:1), the adapter enables an extremely lower noise floor,
especially at high-sensitivity vertical scales (<
400 mV) when compared to the Keysight InfiniiMax III
probe with the N5444A SMA/2.92 mm head.

Measurement versatility
The N2750A Series differential probes offer
2:1 and 10:1 dual attenuation settings, allowing them to be
used for a broad range of applications. Dual attenuation range is automatically configured depending on
尺寸输入信号
The new differential probes have an input resistance of 200 kΩ (differential) or 100 kΩ (each input to
ground) and an extremely low input capacitance of 700 fF to minimize circuit loading. This,
accompanied with superior signal fidelity, makes these probes useful for most digital design and debug
applications. And with their wide dynamic range (10 Vpp) and offset range (
± 15 V), these probes can
be used in a wide variety of analog signal measurements as well.
InfiniiMode usability
The N2750A Series probes come with new InfiniiMode operation modes. The InfiniiMode allows
convenient measurements of differential, single- ended, and common mode signals with a single probe
tip without reconnecting the probe to change the connection. The N2750A probe’s InfiniiMode provides
• B – ground (single-ended B)
• (A+B)/2 – ground (common mode)
The N2750A Series InfiniiMode differential
probes are a new generation of low-cost, 1.5
3.5, and 6 GHz differential active probes compatible with Infiniium oscilloscope’s AutoProbe interface
Quick action scope control
The N2750A Series differential probes provide convenient and quick access to various functions on the
scope. You often have a need to control the scope while you hold a probe in your hand. With the quick
action scope control feature built into the probe, you can turn the built-in headlight of the probe on and
off or control some frequently used scope functions, such as RUN/STOP, auto scale, quick print, and
quick save with only the push of a button on the probe. Get control of your most needed function with a
push of the quick action control button on the probe
Flexibility in probe use models is also a vital necessity. The probes come standard with three different
types of exchangeable probe tips that allow for easy connections to the circuit under test. These probe
tips enable you to access multiple signals on anything from header connectors to hard-to- reach, high-
density circuitry. The probes are equipped with a white LED headlight to illuminate the circuit under test
which will help you see where you are probing
The probes are powered directly by the Infiniium AutoProbe interface, eliminating the need for an
additional power supply
The InfiniiMode probe allows convenient measurements of differential, single- ended (A and B) and

Single-Ended Active Probes — N2795A/96A/97A
• High resistance (1 MΩ) and low capacitance (1 pF) input for low
• Wide input dynamic range (± 8 V) and offset range (
± 12 V for
N2796A/97A
± 8 V for N2795A)
• Built-in headlight
• Direct connection to AutoProbe interface (no power supply required)
• N2797A for extreme temperature environmental chamber testing at
–40 to +85 °C
The N2795A/96A are a new generation of low-cost
1 to 2 GHz single-
ended active probes with the AutoProbe interface (compatible with
Keysight’s Infiniium family of oscilloscopes). These probes integrate
many of the characteristics needed for today’s general-purpose, high-
speed probing–especially in digital system design, component design/characterization, and educational research applications. Its 1 MΩ input resistance and extremely low input capacitance (1 pF) provide ultra low loading of the DUT. This, accompanied with superior signal fidelity
makes these probes useful for most of today’s digital logic voltages.
Testing devices over extreme temperature ranges is quite common these
days. The N2797A
1.5 GHz single-ended active probe is the industry’s
first low-cost high input impedance active probe with rugged probe tips
for environmental chamber testing of ICs and devices. The probe gives
the ability to probe signals at drastic temperature swings ranging from –
40 to +85 °C. The probe provides a
2-m long cable. Order N2798A for
replacement accessories
The N2795A/96A/97A are equipped with a white LED headlight to
illuminate the circuit under test. The probes are powered directly by the
Infiniium AutoProbe interface, eliminating the need for an additional
power supply. The probes also come with a number of accessories that
allow for easy connections to the circuit under test

Power Rail Probes — N7020A
2 GHz Power Rail Probe
• 2- GHz single-ended active probe for power rail noise measurement
• 1.1:1 attenuation ratio ensures low noise signal measurement
•
± 24 V of probe offset range enables effective elimination of DC
component of a power supply
The N7020A power rail probe is a low noise, large offset range
oscilloscope probe that enables users to measure small signals riding
on top of DC power supplies
• Low noise: The N7020A power rail probe is a
1:1 attenuation ratio
active probe. As a general rule, the higher a probes attenuation
ratio, the nosier the signal will be on the oscilloscope
• Large offset range: The N7020A power rail probe provides
± 24 V
of probe offset. This enables users to center the signal on screen
while placing the oscilloscope at its maximum vertical sensitivity

• Low DC loading: The N7020A power rail probe has
50 kΩ input
impedance at DC, minimizing the probe’s DC loading of the power
条件：measuring programmable supplies like those used in micro- controller power saving modes.
• Large input dynamic range: The N7020A power rail probes
± 850 mV input dynamic range means that users can measure up
to 850 mV deviations of their DC supplies. This is very useful for

•
± 15 V probe offset range enables power integrity measurements of
the power rails encountered in high speed systems
The N7024A power rail probe is similar to the N7020A power rail
probe in that they both were designed to provide the user the
ability to zoom-in on their DC power supplies to accurately observe
and measure the ripple, noise and transients riding on these supply
outputs. The N7024A is for the engineer or technician who would
like to use one oscilloscope for both their SI and PI measurements
using Keysight’s Infiniium oscilloscopes. The N7024A includes
multiple connection options: SMA connection (6 GHz), N7021A
pigtail coax (~6 GHz), N7033A fine pitch SMT browser (5 GHz),
N7032A fine pitch SMT browser (4 GHz) and N7023A general
purpose browser (350 MHz).
