HP 10430A 10:1 Probe

The HP 10430A is a 10:1 passive probe engineered for general-purpose oscilloscope measurements across bandwidths up to 500 MHz. This probe minimizes loading effects on circuits under test through high input impedance (1 MΩ) and low input capacitance (6.5 pF), delivering accurate signal reproduction without introducing significant measurement artifacts.

– Technical Specifications

• Attenuation Ratio: 10:1 passive
• Bandwidth: Up to 500 MHz
• Input Impedance: 1 MΩ parallel with 6.5 pF
• Cable Length: 1 meter
• Probe Tip: Narrow, sharp design suitable for surface-mount device probing
• Ground Lead: Alligator clip-style with integrated ferrite bead for noise reduction

– Key Features

The modular construction of the HP 10430A—part of the HP 10400A miniature passive probe family—enables straightforward maintenance and repair. The ferrite-bead-equipped ground lead actively reduces measurement noise, critical for clean signal acquisition on high-frequency circuits. Narrow probe tip geometry provides access to tightly spaced SMT pads without bridging adjacent traces.

– Typical Applications

This probe serves general-purpose oscilloscope work across analog and mixed-signal circuit characterization, signal integrity analysis, and troubleshooting tasks where circuit loading must be minimized. The 500 MHz bandwidth supports measurement of moderately fast digital and RF signals.

– Compatibility & Integration

The HP 10430A connects via standard oscilloscope input connectors and is compatible with instruments such as the HP 54520 and 54540 Series oscilloscopes. It integrates with the full HP 10400A probe family ecosystem, which includes general-purpose grabbers and IC-specific grabber accessories for extended measurement flexibility. System bandwidth is determined by the combined effects of probe input capacitance, source impedance, source bandwidth, and oscilloscope bandwidth—all must be evaluated together for accurate performance prediction.
