Keysight TechnologiesN2750A/51A/52A InfiniiModeDifferential Active ProbesData Sheet

Key FeaturesMeasurement VersatilityMeasurement versatilityThese probes integrate many of thefeatures and characteristics needed fortoday’s general-purpose, high-speeddifferential probing - especially in digitalsystem design, component design/characterization, and differential serialbus measurements. The N2750A Seriesdifferential probes offer 2:1 and 10:1dual attenuation settings, allowingthem to be used for a broad range ofapplications. Dual attenuation range isautomatically configured depending onthe size of the input signal.–– 1.5 GHz, 3.5 GHz, and 6 GHz probebandwidth models–– Dual attenuation ratio (2:1/10:1)–– High input resistance (200 kΩdifferential, 100 kΩ single-ended)–– Wide input dynamic range (10 Vpp)–– Wide offset range ( 15 V)–– High CMRR ( 60 dB at 1 MHz)Superb usability–– InfiniiMode probing for makingdifferential, single-ended andcommon mode measurementswith a single probe–– Built-in multi-function scope controlfor quick access to a variety of scopefunctions–– Built-in “Headlight” to see whereyou are probing–– Includes solder-in, browser, andsocketed tips standard–– AutoProbe interface for autoconfiguration and probe powerAt affordable pricesThe N2750A Series InfiniiModedifferential probes are a new generationof low-cost, 1.5 GHz, 3.5 GHz, and6 GHz differential active probescompatible with the KeysightTechnologies, Inc. InfiniiVision andInfiniium oscilloscopes’ AutoProbeinterface.2The new differential probes have aninput resistance of 200 kΩ (differential)or 100 kΩ (each input to ground) andan extremely low input capacitanceof 700 fF to minimize circuit loading.This, accompanied with superior signalfidelity, makes these probes useful formost digital design and debug applications. And with their wide dynamicrange (10 Vpp) and offset range ( 15 V),these probes can be used in a widevariety of analog signal measurementsas well.

Superb UsabilityInfiniiModeThe N2750A Series probes come withnew InfiniiMode operation modes.The InfiniiMode allows convenientmeasurements of differential, singleended, and common mode signals witha single probe tip without reconnectingthe probe to change the connection.The N2750A probe’s InfiniiModeprovides the following modes ofoperation.–– A – B (differential)–– A – ground (single-ended A)–– B – ground (single-ended B)–– (A B)/2 – ground (common mode)Figure 1. The InfiniiMode allows convenient measurements of differential, single-ended (A, B), andcommon mode signals with a single probe tip without reconnecting the probe to change the connection.Quick action scope controlFor Infiniium oscilloscopes:For InfiniiVision oscilloscopes:The N2750A Series differentialprobes provide convenient and quickaccess to various functions on thescope. You often have a need tocontrol the scope while you hold aprobe in your hand. With the quickaction scope control feature builtinto the probe, you can turn thebuilt-in headlight of the probe on andoff, or control some frequently usedscope functions such as RUN/STOP,auto scale, quick print, quick save,etc. with only a button press onthe probe. Get control of your mostneeded function with a push of thequick action control button on theprobe. The following scope functionscan be controlled with the quickaction control button.–– Headlight on-off/intensity control–– Headlight on-off/intensity control–– InfiniiMode–– InfiniiMode–– Run/stop toggle–– Run/stop toggle–– Single–– Single–– Clear display–– Clear display–– Autoscale–– Autoscale–– No action–– Force trigger–– Multipurpose (mapped to quickaction button)–– Quick action (mapped to quick actionbutton)–– Quick Measure–– Quick Print–– Quick Screen–– Quick Setup–– Quick Waveform–– Quick Email–– Quick Execute–– Quick Control–– Quick measure all–– Quick measure statistics reset–– Quick mask statistics reset–– Quick print–– Quick save–– Quick e-mail–– Quick recall–– Quick freeze display–– Quick trigger mode–– Quick clear display3

Flexibility in probe use models is alsoa vital necessity. The probes comestandard with three different types ofexchangeable probe tips that allow foreasy connections to the circuit undertest. These probe tips enable you toaccess multiple signals on anythingfrom header connectors to hard-toreach, high-density circuitry. Theprobes are equipped with a white LEDheadlight to illuminate the circuit undertest which will help you see where youare probing.The probes are powered directly bythe AutoProbe interface, eliminatingthe need for an additional powersupply. The AutoProbe interface alsoautomatically identifies the probe typefor auto configuration of the probe.Browser tipSolder-in tipSocketed tipMaximum bandwidthUp to 6 GHz warranted,7 GHz typical (with N2752A)Up to 3.5 GHz (with N2751A)Up to 1.5 GHz (with N2750A)Up to 2.5 GHz(with N2751A/52A)Up to 1.5 GHz (with N2750A)Up to 3 GHz(with N2751A/52A)Up to 1.5 GHz (with N2750A)InfiniiModeNoYesYesKey featuresAdjustable pitch spacingDamping R tip(0.5 mm – 7.5 mm),full bandwidth, differential modeonly, head light, damping R tipDamping R tipApplicationsHighest performance (7 GHz),quick and simple hand browsingFor soldering tips directly to testdevices, semi-permanent DUTsignals, differential signals whereSE and common modes need to beinvestigatedFor directly connecting to0.1” header pinsReplacement part numberN2776A (qty 3)N2777A (qty 3)N2778A (qty 3)4
