Agilent/Keysight M9341A

The Keysight M9341A is a PXIe Digital I/O module that bridges PXI Vector Network Analyzers with external test peripherals in automated measurement environments. It provides synchronized control and communication capabilities for handler-driven test workflows, enabling devices to be automatically inserted, tested, and sorted based on RF performance. The module combines 8-bit and 24-bit digital I/O channels in a single card, supporting both legacy benchtop VNA integration and modern modular PXI system architectures.

– Technical Specifications

Connector & Physical Interface
• CHAMP 0.8mm, 36-position receptacle for 24-bit I/O
• Logic-level input and output signals

Digital I/O Capabilities
• 8-bit Digital I/O: Software-selectable clock rates up to 25 MHz with 4-channel RFFE-like interface support
• 24-bit Digital I/O: Direct external peripheral communication
• Triggering ports for measurement synchronization

– Key Features

• Dual I/O architecture supports both handler command protocols and device-level control signals
• Clock rates to 25 MHz enable real-time device manipulation during automated test sequences
• Triggering synchronization ensures precise timing correlation between VNA measurements and external equipment actions
• Single-slot PXIe form factor minimizes chassis footprint in multi-instrument test systems

– Typical Applications

• Automated RF device manufacturing test with handler integration
• Production sort workflows where devices are tested and binned based on S-parameter results
• DUT power sequencing and bias control during network analysis measurements
• Synchronized multi-instrument measurement campaigns requiring external equipment gating

– Compatibility & Integration

PXI Vector Network Analyzers: M980xA Series, M937xA, M9485A

Benchtop Systems: Compatible with 24-bit digital I/O connectors on PNA and ENA Series rear panels

The M9341A integrates into existing Keysight automated test architectures without requiring custom interface development. Comprehensive programming resources including SCPI command references support rapid deployment in LabVIEW, TestStand, and other industry-standard test frameworks.
