Keysight (Agilent) E2679A InfiniiMax Single-ended Solder-in Probe Head

The Keysight E2679A InfiniiMax single-ended solder-in probe head delivers direct circuit access for high-speed signal measurement in complex electronic systems. Its semi-permanent soldered connection minimizes signal distortion and insertion loss, making it the preferred choice for high-bandwidth signal validation and detailed circuit analysis. The probe head operates as part of the InfiniiMax probing ecosystem, combining with compatible amplifiers to achieve specified system performance.

– Technical Specifications

• Bandwidth: Up to 6 GHz
• Input Capacitance: ≤ 270 fF
• Lead Length: 4 inches
• Connection Method: Solder-in (semi-permanent)

– Key Features

• Low loading design with input capacitance ≤ 270 fF minimizes circuit loading effects
• Four-inch lead length enables access to congested areas, including DIMM sockets and tight trace routes
• Supplied with 16 full bandwidth damping resistors, 8 medium bandwidth damping resistors, and 24 zero ohm ground resistors
• Direct solder connection provides stable, long-term measurement stability without drift or connection intermittence
• Replacement damping resistor kits available (E2672A)

– Typical Applications

• High-speed digital design validation and debug
• Multi-gigahertz signal integrity measurements
• Circuit characterization requiring semi-permanent probe placement
• DDR, processor, and high-speed serial link analysis

– Compatibility & Integration

The E2679A belongs to the InfiniiMax I probe family and operates with InfiniiMax I and II probe amplifiers. System bandwidth is limited to the lower of the probe head or amplifier specification. The E2679A is not compatible with InfiniiMax III or III+ systems. A RoHS-compliant variant (E2679B) is functionally equivalent and available as an alternative.
