N2839A

N2839A is a 21GHz InfiniiMax II differential browser head. It brings the measurement fidelity of a solder-in probe head to hand-held browsing. The probe tips of the N2839A ensure a secure connection to DUT. The probe tips can be adjusted to accommodate targets from 0mm to 3mm apart using the thumbwheel and can be easily and quickly replaced if accidental damage occurs. The low-inductance ground spring ensures that the probe’s frequency response remains constant regardless of the span range setting. Unlike conventional probe browsers in this class, the N2839A provides extremely low probe loading. As the signal speed increases, the capacitance element of the probe’s input becomes a dominant factor in determining the amount of probe loading. The larger the input capacitances, the more the probe may load the DUT or affect the response of the measurement when the measured frequency increases.

• 21GHz bandwidth (when used with InfiniiMax Ultra MX0025A) and 12 GHz (when used with 1169B)
• Extremely low loading (0.21pF – about the same as the N5381B solder-in head)
• Ground spring helps maintain probe’s frequency response constant regardless of span range setting
• Thumbwheel controlled span adjustable from 0mm to 3mm
• Comes with browser head, 40x replaceable tips, protective cap and ESD-safe tweezer
• Compatible with InfiniiMax I (1130B/31B/32B/34B) and InfiniiMax II amplifiers (1168B/69B)
