The Keysight N2881A is a pair of DC blocking capacitors engineered to eliminate unwanted DC components from input signals in precision measurement applications. This accessory integrates with the N2880A InfiniiMax in-line attenuator to protect sensitive test equipment and preserve signal integrity in oscilloscopes, logic analyzers, and other instruments where DC voltage presence can degrade measurement accuracy or cause equipment damage.
– Technical Specifications
• Product Type: DC Blocking Capacitors
• Quantity: Pair (kit of 2)
• DC Voltage Blocking Capability: Up to 30 V
• Series Compatibility: InfiniiMax III Series
– Key Features
• Blocks unwanted DC signal components at the input stage
• Designed for seamless integration within the InfiniiMax probing architecture
• Rated for DC voltage blocking up to 30 V
• Supplied as a matched pair for dual-channel or redundant blocking applications
– Typical Applications
• Oscilloscope front-end protection from DC offset voltages
• Logic analyzer input conditioning
• Precision instrumentation requiring DC rejection at signal entry
• High-speed digital and analog signal measurement chains
– Compatibility & Integration
The N2881A is designed for use with the Keysight N2880A InfiniiMax in-line attenuator and operates within the InfiniiMax III Series ecosystem. Integration occurs at the signal input path, allowing DC blocking to occur before signal reaches sensitive measurement circuitry.
