Agilent/Keysight 34138A

The Keysight 34138A is a precision test lead set engineered for connectivity across a wide range of digital multimeters and benchtop test instruments. This accessory kit delivers reliable signal transmission and measurement accuracy in field and laboratory environments through fixed sheath banana plug termination and multiple probe configurations.

Technical Specifications

• Termination: Fixed sheath banana plugs


• Cable Length: 1.4 meters


• Safety Rating: 1000 V CAT II


• Compliance: IEC 61010-031

Key Features

• Two test lead probes with retractable sheath for general-purpose measurements


• Two fine tip probes for precision contact on small test points


• Two SMT grabbers for surface-mount component testing


• Single mini grabber for confined spaces and selective probing


• Banana plug interface accommodates all standard multimeter input terminals

Typical Applications The 34138A serves demanding measurement scenarios including benchtop characterization, field service work, component-level diagnostics, and production test environments. The mixed probe set enables transitions between general circuit testing, sensitive analog measurements, and SMT board verification without requiring multiple accessory purchases.

Compatibility & Integration The 34138A connects directly to all Keysight/Agilent multimeters featuring banana plug inputs, including the 34460A, 34461A, 34401A, 34405A, 34410A, 34411A, L4411A, and U2741A. The set is compatible with both handheld and benchtop instruments using standard 4 mm banana connectors. Note: The 3458A requires the 34137A test lead set. Verify banana plug compatibility before deployment with non-Keysight instruments.
