Agilent/Keysight MX0020A

The Keysight MX0020A is a 10 GHz InfiniiMax Ultra Series probe amplifier engineered for high-fidelity signal integrity measurements. It delivers minimal loading and superior signal preservation through an RC input impedance architecture, enabling accurate probing of modern high-speed designs without signal distortion. Three auto-switchable attenuation ratios and lowest-in-class noise across all ranges make it the choice for demanding analog and mixed-signal debug work.

Technical Specifications

Bandwidth: 10 GHz Input Impedance:

• 25 kΩ ±2% single-ended (with 25 kΩ probe heads)


• 50 kΩ ±2% differential


• RC high-impedance profile minimizes mid-band capacitive loading Input Dynamic Range:


• 600 mVpp @ 1:1 attenuation


• 2.5 Vpp @ 4:1 attenuation


• 5 Vpp @ 8:1 attenuation Attenuation: 1:1, 4:1, 8:1 (auto-switchable) Input Common Mode Range:


• ±8 V DC to 100 Hz


• ±0.5 V @ 1:1 attenuation (>100 Hz)


• ±4 V @ 4:1 attenuation (>100 Hz) Offset Range: ±16 V Maximum Input Voltage: 18 V peak CAT I

Key Features

• Three attenuation ranges deliver lowest noise performance across full bandwidth


• Lowest capacitive loading due to RC input impedance profile


• AutoProbe II interface (3.5 mm) enables auto-configuration and probe power delivery on compatible oscilloscopes


• Cable and connector assembly totals 1346.2 mm; cable only 1181.1 mm


• Ground connection terminal for DUTs not grounded to scope via mains earth

Typical Applications High-speed signal integrity analysis, embedded system debug, power integrity measurements, and jitter characterization on systems requiring minimal probe loading and maximum signal fidelity.
