Product

Precision DMM measurements require probe connections that maintain signal integrity while providing mechanical flexibility across diverse test points. The Keysight 34137A deluxe test lead set delivers professional-grade connectivity designed specifically for the 3458A 8.5-digit digital multimeter’s exacting measurement requirements.

## Technical Specifications

• Cable length: 1.4 meters
• Primary voltage rating: 1000V CAT II per IEC 61010-031
• Accessory voltage rating: 300V CAT II (when fitted with included probes)
• Connector type: Retractable sheath banana plugs
• Probe complement: 2 test leads, 2 fine tip probes, 2 SMT grabbers, 1 mini grabber
• Safety compliance: IEC 61010-031 overvoltage category standards

## Key Features

Retractable sheath banana plugs eliminate accidental shorts during live circuit testing while maintaining low contact resistance for sub-ppm measurements. The 1.4-meter length provides adequate reach for benchtop and rack-mounted configurations without introducing excessive capacitance that degrades high-impedance measurements. Fine tip probes enable precision contact with 0.5mm pitch components and via holes. SMT grabbers secure connections to surface-mount components without mechanical stress on solder joints. The mini grabber handles wire connections and component leads where standard probes cannot establish reliable contact.

## Typical Applications

Calibration laboratories performing traceable measurements to NIST standards require the voltage isolation and low thermal EMF characteristics. Semiconductor device characterization benefits from the fine tip probes for die-level measurements and package pin access. Power electronics testing utilizes the 1000V CAT II rating for switching circuit analysis and efficiency measurements. Aerospace and defense applications leverage the safety compliance for MIL-STD equipment verification. Medical device testing employs the accessory variety for FDA validation measurements across diverse circuit topologies.

## Compatibility & Integration

Engineered exclusively for the Keysight 3458A digital multimeter’s input impedance and measurement architecture. The banana plug terminations mate directly with the 3458A front panel inputs without adapters. Probe accessories maintain the instrument’s specified measurement uncertainty through controlled parasitic parameters. The lead set preserves the 3458A’s 100MΩ input impedance characteristics essential for high-accuracy DC voltage measurements.
