LeCroy DXC-5100 Differential Probe Pair, 250MHz

The LeCroy DXC-5100 is a passive differential probe pair that adds true differential measurement capability to oscilloscopes equipped only with single-ended inputs. Operating at 250 MHz bandwidth, this probe pair features selectable 100:1 or 10:1 attenuation ratios and can work with Teledyne LeCroy differential amplifiers for signal conditioning and measurement of differential signals in high-speed applications.

Technical Specifications

• Bandwidth: 250 MHz


• Attenuation Ratio: Selectable 100:1 or 10:1


• Input Resistance: 10 MΩ or 40 MΩ (100:1 attenuation); 1 MΩ (10:1 attenuation)


• Input Capacitance: 2.75 pF


• Maximum Input Voltage: 2500 V differential

Key Features

• Passive attenuation design minimizes circuit loading and maintains signal integrity


• Low input capacitance (2.75 pF) reduces probe-induced distortion at higher frequencies


• High input impedance options preserve circuit characteristics during measurement


• Selectable attenuation enables flexible gain configuration for varying signal amplitudes


• Black finish and compact 1.2 m cable length support bench and in-circuit measurements

System Performance When paired with differential amplifiers, the DXC-5100 achieves extended bandwidth performance: up to 100 MHz with DA1855A amplifiers and up to 10 MHz with DA1822 amplifiers. Common mode rejection capabilities support precision differential measurements across diverse signal environments.

Compatibility & Integration The DXC-5100 operates as a passive attenuator within the DXC probe ecosystem and requires compatible Teledyne LeCroy differential amplifiers - including DA101, DA1855A, or DA1822 - for full measurement performance. This architecture enables modular configuration across oscilloscopes, network analyzers, and spectrum analyzers that support ProBus connectivity and differential signal conditioning.
