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 is designed to 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
• Cable Length: 1.2 m
• Connector: Teledyne LeCroy ProBus

– 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.
