Agilent/Keysight 10431A

The Agilent/Keysight 10431A is a miniature passive probe designed for general-purpose and integrated circuit measurements, offering modular construction for enhanced reliability and reduced repair costs. Its design features a narrow, sharp probe tip suitable for probing surface mount technology. This probe is part of the Keysight 10400 miniature probe family, known for its superior electrical performance and modularity, allowing individual replacement of probe tips, cables, and chassis assemblies.

### Technical Specifications

* **Model:** Agilent/Keysight 10431A
* **Type:** Miniature Passive Probe
* **Division Ratio:** 10:1
* **Length:** 1 m
* **Typical Scope Bandwidth:** 500 MHz
* **Circuit Loading (1 MΩ scope input):** 1 MΩ; 6.5 pF
* **Compensates Oscilloscope Input:** 1 MΩ; 6 to 9 pF

### Components and Accessories

The Agilent/Keysight 10431A includes a variety of accessories to facilitate different measurement needs:

* **Narrow, Sharp Probe Tip:** Designed for precise probing of surface mount components.
* **General Purpose Grabber:** Attaches to the probe tip for general circuit measurements and probing IC pins.
* **Integrated Circuit Grabber:** Designed for easy and firm gripping of ICs with 0.1-inch pitch, minimizing the risk of shorting adjacent pins.
* **Ground Lead:** An alligator clip-style ground lead with an integrated ferrite bead to reduce noise in the measured signal.
* **Barrel Insulator:** Prevents shorting of the probe tip and circuitry, ensuring correct fit when used with the general-purpose grabber.
* **Accessory Package:** Contains four grounding spanners for high-frequency measurements, one barrel insulator, eight colored cable markers, and one adjustment screwdriver.

### Electrical Characteristics

* The probe utilizes a 50 Ω transmission line for its cable and is designed for use with oscilloscopes featuring a 50 Ω input. High impedance inputs can be used with a 50 Ω feed-thru termination.
* The coaxial transmission line design minimizes cable capacitance effects. The probe’s input resistance is low, specified as 500 times the probe’s attenuation factor. Input capacitance is also low, primarily consisting of stray capacitance at the probe tip, typically around 1 pF.
* Resistive divider probes like the 10431A offer excellent system bandwidth, making them suitable for high-frequency applications where circuit impedances are typically low. Care should be taken to avoid overheating the probe’s voltage division resistor or the 50 Ω cable termination resistor.

### Compatibility

The 10431A probe is compatible with various Keysight/Agilent oscilloscopes. Specific model compatibility includes:

* 10431A2 is compatible with 1631A/D, 1715/22/25/26/27, 5185, 1805/09, 54200/2013, 54501A.
