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.
