Continuing the probe head topology pioneered by Keysight Technologies, Inc. in the InfiniiMax RC probe systems, ten probe heads are provided to accommodate multiple-use models: a 52 GHz solder-in shows the unparalleled performance, a 30 GHz browser that is extremely usable, a 25/28 GHz ZIF probe head with economical replaceable/removable ZIF tips, a 30 GHz 2.92 mm probe head which allows cabled measurements using 2.92 mm, 3.5...

More accurate probe correction Each individual InfiniiMax RCRC 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 flatten the probe’s magnitude and phase response for accuracy. Traditionally, probe correction uses a nominal model based on a typical probe amplifier instead of the specific amplifier’s data, collected during the final steps of production. Generally, the biggest variation between probing systems is a result of the probe amplifier. The ability to correct a specific probe amplifier’s response...

The MX0045A adapters seamlessly bridge the InfiniiMax 4 with previous generations of InfiniiMax III/III+ probe systems, substantially broadening the selection of compatible probe heads. This compatibility extends to earlier generation probe heads such as the N5445A Browser, N5444A SMA head, N5439A ZIF head, among others, providing users with a wide range of probing options. 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 to 125 mil (or 0.5 mm to 3.1 mm). The span between...

The N2848A/49A QuickTip offers a 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 InfiniiMode probing when used with the InfiniiMax III+ probe amp and supports differential probing with the InfiniiMax III probe amp. The N2849A QuickTip...

The N5444A 2.92 mm/3.5 mm/SMA probe head (30 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 N5448B 2.92 mm head flex cables (10” or 25 cm) or N2823A 2.92 mm cables with 1 m to extend the cable length and add convenience. You can control the termination voltage of the N5444A probe head using either the Infiniium scope software or by using a N5444-61601 cable included in the N5444A kit connected to your own DC power supply. For extended temperature testing with extreme temperature range measurements, the MX0109A...

The N5449A high impedance adapter allows connection for probes that require a high impedance scope input such as a high impedance passive probe, 1147B/N2893A current probe, or N2790A differential probe to the Infiniium V, 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 InfiniiMax III probing system fully compatible with the Infiniium 86100C DCA-J sampling oscilloscope. Previously the DCA-J was limited to 13 GHz...
