measuring differential and single-ended signals, with exible connectivity solutions for
today’s high-density ICs and circuit boards. Four different InniiMax III probe ampliers
ranging from 16 GHz to 30 GHz are available for matching your probing solution to your
performance and budget requirements. A proprietary 200 GHz f T InP (indium phosphide)
IC process with backside ground vias and novel thick lm technology is utilized to
accommodate your highest performance needs and is unmatched by any product in
the market.

InniiMax III probe amplier

The N2830A /N7000A Series InniiMax III+ probing system is the next generation of
InniiMax probing, greatly expanding the measurement capabilities and usability of a
probe capable of measuring all components of a differential signal. The built-in InniiMode
technology allows you to switch to differential, single-ended, and common mode without
adjusting probe tip connections. The InniiMax III+ probe’s InniiMode 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)

–
The InniiMax III+ works with the full array of InniiMax III probe heads and supports
the full bandwidth of the InniiMax III+.

Highest delity and accuracy

The InniiMax III provides the highest bandwidth and incredibly
low loading to allow for a new level of signal delity and accuracy.
Continuing the probe head topology pioneered by Keysight
Technologies, Inc. in the InniiMax I and II probe systems, ve
probe heads are provided to accommodate multiple use models:
a 30 GHz browser that is extremely usable, a 25/28 GHz ZIF probe
head with economical replaceable/removable ZIF tips, a 28 GHz

2.92 mm probe head which allows cabled measurements using

2.92 mm, 3.5 mm, or SMA coax cables, an economical 16/26 GHz
solder-in probe head for demanding measurements, and a 16 GHz
QuickTip for a quick and secure connection.

More accurate probe correction

Each individual InniiMax III and III+ probe amp contains its
unique S-parameters, and this frequency response data is used
with the S-parameters of the various probe heads to further
atten the probe’s magnitude and phase response for accuracy.
Traditionally, probe correction uses a nominal model based on a
typical probe amplier instead of the specic amplier. Generally,
the biggest variation between probing systems is a result of the
probe amplier. The ability to correct a specic probe amplier’s
response results in a more accurate probe correction, which
yields a more accurate measurement.

Uncompromised Usability

Extensive line-up of probe heads and accessories

Keysight’s InniiMax III/III+ probes support a wide variety of
high-speed applications with an ex tensive line-up of probe heads
and accessories.

– The N5445A browser head (30 GHz) is the best choice for

quick general-purpose troubleshooting of differential signals
with its z-axis compliance and variable spacing from 20 mil
– 125 mil (or 0.5 mm – 3.1 mm). The span between the signal
tips is easily adjusted with a thumb wheel on the browser.
Integrated LED lighting at the tip illuminates the probing area
for better visibility. Order N5476A for replacement browser
tips (set of 4).

– The N2848A /49A QuickTip offers the industry’s rst

magnetically-engaged probe head and tip for a quick and
secure connection, pushing the usability to the next level.
The N2848A QuickTip probe head quickly snaps to the
N2849A probe tip, utilizing magnets to connect to the two
sides of the differential signal and ground. Multiple N2849A
probe tips can be installed on a DUT, allowing quick and
reliable measurement of many probe points. The QuickTip
supports the InniiMode probing when used with the
InniiMax III+ probe amp and supports differential probing
with the InniiMax III probe amp. The N2849A QuickTip tips
can also be used with the InniiMax I/II probe amps when
used in conjunction with the N2851A QuickTip probe head
for InniiMax I/II.

– The N5439A ZIF probe head provides 28 GHz bandwidth in

an economical replaceable tip form factor. For differential
measurement, the N5439A ZIF probe head with the N5440A
or N5447A ceramic ZIF tip provides the industry’s lowest
signal loading. The ZIF tips can be left on the DUT as the
probe head is moved from one probing site to the next. Order
N5440A (450 Ω ceramic), N5447A (200 Ω ceramic) or the new
N2838A (450 Ω PC board) for a set of 5 ZIF tips with plastic
sporks to aid in soldering the tips to your DUT. The N2838A
PC board ZIF tip increased the robustness of the ZIF tip
signicantly while maintaining the bandwidth performance
up to 25 GHz when used in conjunction with the N2803A and
N5439A. Variable spacing from 5 mil – 80 mil (or 0.127 mm
– 2 mm). (The N5447A 200 Ω ZIF tip is not compatible with
InniiMax III+ probes.)

– The N5444A 2.92 mm/3.5 mm/SMA probe head (28 GHz)

allows you to connect two 2.92 mm, 3.5 mm or SMA cables
to make a differential measurement on a single oscilloscope
channel. Order N5448A 2.92 mm head ex cables (10” or
25 cm) to extend the cable length and add convenience.

– The N5441A solder-in probe head is an economical,

semi-permanent connection that provides up to 16 GHz
of bandwidth. Variable span of the leads ranges from
5 mil – 80 mil (or 0.127 mm – 2 mm).
