Keysight (Agilent) E2655B Probe Deskew and Performance Verification Kit

The Keysight (Agilent) E2655B Probe Deskew and Performance Verification Kit is a calibration accessory designed to verify measurement accuracy and compensate for timing differences between InfiniiMax active probe channels. The kIt has essential deskew and performance verification procedures to ensure probe integrity meets specified parameters. This legacy product was discontinued with end-of-support on March 1, 2018; the E2655C is the recommended replacement.

Technical Specifications

The E2655B comprises a deskew fixture and interconnect adapters to establish known reference conditions for calibration procedures:

• De-skew fixture - primary component providing reference standard for deskew and performance verification


• SMA (male) to SMA (male) adapter


• SMA (male) to BNC (female) adapter


• BNC (male) to SMA (male) adapter


• 50 Ω SMA terminator - load resistor for signal integrity and accurate measurements Kit weight: 0.5 lbs; dimensions: 1 × 5 × 2 inches.

Key Features The kit enables precise channel deskew calibration to eliminate timing skew across probe channels. SMA and BNC adapter interfaces support integration with standard laboratory test equipment. The 50 Ω terminator ensures proper signal termination during verification procedures, critical for maintaining measurement fidelity across frequency-dependent probe response.

Typical Applications Probe calibration and performance verification workflows. Deskew procedures for multi-channel measurements where phase alignment between channels must be characterized and corrected. Pre-measurement validation to confirm InfiniiMax probe performance remains within specification.

Compatibility & Integration The E2655B works with Keysight InfiniiMax series active probes. While specific E2655B compatibility details are limited due to legacy status, the successor E2655C is compatible with InfiniiMax I (1130B, 1131B, 1132B, 1134B), InfiniiMax II (1168B, 1169B), InfiniiMax III+ and Ultra series probe amplifiers with bandwidths less than 13 GHz, and N2750/1/2A differential probes. For InfiniiMax probes exceeding 13 GHz bandwidth, the MX0104A accessory may be required.
