Single-ended Active Probes - N2795A/96A Active Probes

• High resistance (1MΩ) and low

capacitance (1 pF) input for low

• Wide input dynamic range (±8 V)

and offset range (±12 V for N2796A,

±8 V for N2795A)

• Built-in headlight

• Direct connection to AutoProbe

interface (no power supply required)

• Provides full system bandwidth

with Infiniium oscilloscopes with

bandwidths up to 1 GHz

The N2795A/96A are a new generation

of low-cost, 1 to 2 GHz single-ended

active probes with the AutoProbe interface

(compatible with Agilent’s Infiniium family

of oscilloscopes). These probes integrate

many of the characteristics needed for

today’s general-purpose, high-speed prob-

ing―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. And

with their wide dynamic range (±8 V) and

offset range (±12 V for N2796A, ±8 V for

N2795A), these probes can be used in a

wide variety of applications. For high signal

integrity probing, the N2795A

1 GHz and N2796A 2 GHz active probes are

perfect complements to Agilent’s 500 to

600 MHz and 1 GHz bandwidth scopes,

respectively.

The N2795A/96A 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 connec-

tions to the circuit under test.
