The Keysight N2880A is an InfiniiMax In-line Attenuator Kit that extends the measurement dynamic range and offset capabilities of compatible InfiniiMax probing systems. By inserting selectable attenuation stages into the signal path, the kit enables measurement of larger amplitude signals and wider DC offset ranges without compromising bandwidth or rise time performance. The N2880A ships with three pairs of coaxial attenuators offering 6 dB, 12 dB, and 20 dB attenuation levels, allowing flexible signal conditioning for demanding high-speed measurement applications.
Technical Specifications
• Attenuation levels: 6 dB, 12 dB, 20 dB per pair
• Dynamic range extension: Up to 50 Vpp
• Offset range extension: Up to ±30 V
• Form factor: In-line coaxial attenuator kit
• Bandwidth impact: No degradation
• Rise time impact: No degradation
– Key Features
• Three switchable attenuation options for tailored signal conditioning
• Preserves probe system bandwidth and rise time characteristics
• Expands measurement capability beyond standard probe amplifier specifications
• Operates with InfiniiMax III series and earlier compatible systems
– Typical Applications
• High-amplitude signal acquisition with fast edge rates
• Extended dynamic range measurements on digital and analog circuits
• Offset-biased signal characterization beyond standard probe limits
• Multi-level logic and power integrity testing
– Compatibility & Integration
The N2880A integrates with Keysight InfiniiMax probe systems, including the 113xA and 1168A/69A series. It functions as a signal conditioning accessory and requires a compatible probe amplifier and head for operation. The kit expands the 5 Vpp dynamic range of 113xA series probes and the 3.3 Vpp range of 1168A/69A series probes, making it essential for applications exceeding standard probe specifications.
