The Keysight 3446ACCU is an accessory kit engineered to expand the measurement capabilities and usability of the 34460A Truevolt Series digital multimeter. This curated collection of components and software tools enables users to optimize test setup flexibility and system integration, making it an ideal upgrade or standard inclusion with compatible instruments.
Technical Specifications
The kit bundles five core elements designed for seamless integration with Truevolt Series multimeters:
• 34138A Test Lead Set with multi-tip probe configuration
• USB cable for computer connectivity and data transfer
• Documentation CD containing user manuals
• IO Libraries CD for instrument control software
– Key Features
The 34138A Test Lead Set provides versatile measurement access across diverse component geometries and PCB layouts. Standard probes deliver conventional lead-based connectivity. Fine tip probes enable measurements on high-density circuitry and tight trace spacing. SMT grabbers and mini grabber attachments address surface-mount device testing without mechanical stress or contact degradation.
USB connectivity enables direct data transfer to host computers, supporting automated test sequences and real-time data logging. The IO Libraries software facilitates GPIB, USB, and Ethernet instrument communication, streamlining multi-instrument test orchestration.
– Compatibility & Integration
The 3446ACCU is designated as the standard accessory package for the 34460A digital multimeter and ships as the bundled kit with both 34460A and 34461A Truevolt Series instruments. This kit serves equally well as a standalone upgrade for users expanding existing 34460A deployments.
Integration with Keysight’s IO Libraries ecosystem provides interoperability with established test automation frameworks and data acquisition systems, eliminating custom driver development for USB and software-based control interfaces.
