Industry-leading probe performance
The InniiMax III probing system of fers you the highest performance available for 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).
05 | Keysight | InniiMax III/III+ Probing System – Data Sheet
– The N2836A solder-in head provides up to 26 GHz bandwidth
when used in conjunction with the N2803A probe amplier. This probe head supports InniiMode probing when used with the InniiMax III+ probe amp.
– The N5442A Precision BNC 50 Ω adapter allows you to
use your existing InniiMax I (1130A-1134A), InniiMax II (1168A/69A), N2750A-52A, N2795A-97A active probes or a general purpose 50 Ω BNC cable with the 90000 X- or 90000 Q-Series oscilloscope.
– The N5449A high impedance adapter allows connection for
probes that require a high impedance scope input such as a high impedance passive probe, 1147B current probe, or N2790A differential probe to the Inniium 90000-X/Q Series oscilloscopes. The N5449A provides switchable AC/DC coupling as well as 10:1 and 1:1 attenuation settings. The adapter comes with a N2873A 500 MHz 10:1 passive probe.
– The N5477A sampling oscilloscope adapter makes the
InniiMax III probing system fully compatible with the Inniium 86100C DCA-J sampling oscilloscope. Previously the DCA-J was limited to 13 GHz of probing, but with the N5477A, the DCA-J now has 30 GHz of probing, increasing its performance and exibility. To use the InniiMax III+ probe on sampling oscilloscopes, order the N1022B probe adapter and the 1143A probe offset control and power module.
– The N5443A performance verication and deskew xture
is required to calibrate and verify the performance of the InniiMax III probe. Keysight is currently the only oscilloscope vendor in the market that provides the hardware for customers to validate their high performance probing system. Order E2655C to calibrate and verify the performance of the InniiMax III+ probes.
Bandwidth upgradability (for InniiMax III)
As frequencies have continued to increase, so have the cost of probes. The InniiMax III system offers the world’s rst fully upgradable probe amplier. Purchase a 16 GHz probe amplier today, knowing that in the future, you can upgrade the amplier to higher bandwidths (20/25/30 GHz) at a fraction of the cost of a new probe amplier.
