This probe is a high-performance device that ESD can quickly and imperceptibly damage or destroy.
Always work at a static-safe workstation and wear a wrist strap when handling probe components. Refer
to the user’s guide. To connect the probe to the oscilloscope, follow these four steps.
When disconnecting the probe amplifier from the scope, always disconnect the probe head from the
amplifier first.

When probing, you can
move the probing site
without breaking the
head-to-amplifier connection.
EXCEPTION: Break the
connection before moving an
N2836A or MX0109A solder-in
probe head.
Probe Head
Probe Amplifier
If the DUT is not grounded
to the oscilloscope via the
AC mains ground, connect
the DUT ground to the oscillo-
scope ground. An example of a
floating ground is a battery
powered DUT.
Connect the probe
head to the DUT.
The probe amplifier
must not be connected to
the oscilloscope or the probe
head!
Connect the
probe amplifier
to the oscillo-
scope. Do not connect
the probe head to the
amplifier at this time.
CAUTION. Risk of damage due to electrostatic discharge (ESD)
Connect the probe
head to the probe
amplifier.
Additional Accessories
– N5477A for connecting the N7000/1/2/3A probes to Infiniium 86100D DCA-X sampling oscillo-
scope or other RF instruments.
– N2787A 3D probe positioner for holding the browser or probe amplifier.
– Strain relief putty (N5439-65201).
– N5450B Extreme Temperature Extension Cable. See user’s guide for more information.
– E2655C or N5443A PV Fixture. Required to calibrate, deskew, and verify the performance of the
probe. Properly positions the probe for performance verification testing.

– BW up to 30 GHz
– Replacement tips, ground blades, and
ground screws available.
– Best handheld probe for differential
and single-ended signals
– Spring-loaded tips and variable
spacing (0.5 mm to 3.1 mm, use
thumbwheel to adjust)
– Using the N2787A 3D probe positioner
with the N5445A browser probe head
reduces the chance of browser tips
breakage and ensures that the tips
maintain solid contact.
