Agilent/Keysight 0950-3384

The Agilent/Keysight 0950-3384 is a switching power supply assembly engineered to deliver stable, regulated DC power across multiple voltage rails for network analyzers and related test equipment. Operating at 103 kHz switching frequency, the supply features automatic input voltage sensing and dual-range operation (90–132 Vac or 195–250 Vac), eliminating manual configuration and supporting global deployment scenarios.

Technical Specifications

The 0950-3384 generates nine distinct output voltage rails: +5.2 V, −5.2 V, +9 V, +15 V, −15 V, +22 V, and a dedicated +15 V standby line that remains powered when the analyzer is off. The supply also provides VCC (5.2 V) and VDL (3.3 V) rails directly to the A15 CPU board assembly. An additional +32 V line is generated on the A14 motherboard from the +22 V output. The +15 V standby rail operates continuously whenever the supply is plugged in, powering front panel indicator LEDs and CPU components during offline periods without requiring full system activation.

Key Features

• Automatic input voltage sensing and switching between 90–132 Vac and 195–250 Vac ranges


• Nine discrete output voltage channels supporting analog and digital subsystems


• Dedicated standby power rail for always-on front panel and CPU functions


• Fixed 103 kHz switching frequency for predictable EMI filtering and thermal management


• Designed for hot-swap field replacement using standard TORX tools

Typical Applications The 0950-3384 is the primary power distribution module in network analyzers and microwave test instruments requiring multi-rail power architecture with integrated standby functionality.

Compatibility & Integration Directly compatible with Agilent/Keysight N338xA Series PNA Network Analyzers, E8356A, E8357A, E8358A, E8801A, E8802A, E8803A, N3381A, N3382A, and N3383A platforms. Replacement requires T-10 and T-20 TORX drivers and ESD grounding precautions.
