The Keysight N2848A is a passive probe head engineered for high-frequency differential and single-ended measurements with InfiniiMax III and III+ probe amplifiers. Its magnetically-engaged design enables rapid connection and disconnection at multiple test points without re-soldering, making it ideal for dynamic measurement scenarios. The probe head supports InfiniiMode probing with InfiniiMax III+ amplifiers and conventional differential probing with InfiniiMax III amplifiers, delivering bandwidth up to 16 GHz and 13 GHz respectively. Multiple N2849A QuickTip probe tips can be deployed simultaneously on a device under test, permitting efficient characterization of numerous points. The N2848A operates reliably in extreme temperature environments, including temperature chamber applications.
Technical Specifications
• Bandwidth: Up to 16 GHz with InfiniiMax III amplifiers; up to 13 GHz with InfiniiMax III+ amplifiers
• Probe Tip Connector: Magnetic engagement with N2849A QuickTip (sold separately)
• Measurement Modes: InfiniiMode (with III+); differential probing (with III)
• Signal Connectivity: Two signal inputs (+, −) for differential and single-ended measurements
• Temperature Rating: Suitable for extreme temperature environments
– Key Features
• Magnetically-engaged probe head and tip for quick, secure connection
• Eliminates need for re-soldering probe leads between measurement points
• Multiple probe tips installable simultaneously on DUT for parallel measurement acquisition
• Ground connection via magnetic engagement to differential signal leads
– Typical Applications
• High-frequency differential signal characterization in RF and microwave circuits
• Multi-point simultaneous probing in semiconductor and PCB testing
• Temperature chamber measurements requiring rapid probe repositioning
• Single-ended and common-mode signal acquisition without connection rework
– Compatibility & Integration
The N2848A is compatible exclusively with Keysight InfiniiMax III and III+ probe amplifiers. Operation with N2800A-series InfiniiMax III probes activates only the two signal inputs for differential and single-ended measurements. The N2849A QuickTip is cross-compatible with the N2851A InfiniiMax II QuickTip probe head for legacy system integration.
