Agilent/Keysight 44727A

The Agilent/Keysight 44727A is a four-channel digital-to-analog converter module engineered for integration into the Agilent/Keysight 3852A Control Unit. Each isolated channel configures independently via jumper selection to deliver unipolar voltage, bipolar voltage, or unipolar current output. The module supports flexible interconnection - series connection expands voltage ranges while parallel connection extends current capability.

Voltage output channels feature remote sense capability to compensate for load-line drops and ensure accurate voltage delivery at the device under test.

Technical Specifications

• Channels: 4 isolated channels per module


• Output Configurations: Unipolar voltage, bipolar voltage, or unipolar current (jumper-selectable per channel)


• Voltage Output: Remote sense available for accurate load voltage regulation


• Current Output: Unipolar configuration


• Interconnection: Channels support series connection for voltage expansion and parallel connection for current expansion

Key Features

• Jumper-configurable channel operation eliminates fixed-function limitations


• Isolated channels enable independent or interconnected operation without crosstalk


• Remote sense on voltage outputs maintains accuracy across varying load impedances


• Direct DC output - no modulation or signal conditioning required

Typical Applications

• Precision voltage and current sourcing in automated test equipment (ATE)


• Multi-axis control systems requiring isolated analog outputs


• Device characterization and stress testing with extended voltage or current ranges


• Integration into larger data acquisition and control frameworks

Compatibility & Integration The 44727A installs directly into the Agilent/Keysight 3852A Control Unit mainframe. Module-level compatibility ensures seamless integration with the 3852A's control architecture and measurement subsystems.
