The Agilent/Keysight N2870A is a passive 1:1 probe engineered for low-level signal acquisition across DC to 35 MHz. Its compact 2.5 mm probe head provides superior access to fine-pitched components and densely populated circuit boards. The probe delivers 1 MΩ input resistance, 39 pF input capacitance, and handles maximum input voltages of 30 Vrms (mains isolated) or 60 Vdc, making it suitable for general-purpose bench and production testing.
