InfiniiMode Active Probes and Accessories
N2750A-52A InfiniiMode probe
• 1.5 - 6 GHz bandwidth
• Dual attenuation ratio (2:1/10:1)
• InfiniiMode probing for making
differential, single-ended and
common mode measurements with
a single probe
• Built-in quick action scope control
for quick access to a variety of
scope functions
• Built-in headlight
• Includes solder-in, browser, and
socketed tips standard
• AutoProbe interface for auto
configuration and probe power
The N2750A Series InfiniiMode
differential probe is a new generation
of low-cost, differential active probe
compatible with InfiniiVision 3000 X-,
4000 X-, 6000 X-Series and Infiniium
oscilloscope’s AutoProbe interface.
Measurement versatility
The N2750A Series InfiniiMode probe
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 the size of
the input signal.
The new differential probe has
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 comes 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 the following
modes of operation.
• A – B (differential),
• A – ground (single-ended A)
• B – ground (single-ended B)
• (A+B)/2 – ground (common mode)
Quick action scope control
The N2750A Series InfiniiMode probe
provides 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, quick save, etc. with only
a button press 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.
This probe is compatible with
InfiniiVision 3000 X-Series with
software ver 2.2 or above, 4000
X-Series with software ver 3.01
or above, and 6000 X-Series with
software ver. 6.00.
