This unit
The Agilent/Keysight E1446A is a VXIbus C-size, register-based summing amplifier and 16-bit digital-to-analog converter (DAC) module for precision signal processing and data acquisition in automated test systems. It combines two input signal summing with programmable DC offset generation and analog signal scaling. The module drives 20 Vp-p into 50-Ohm loads and 40 Vp-p into high-impedance loads, making it suitable for demanding industrial and scientific test applications.
Technical Specifications
- Module Type: VXIbus C-size, one-slot, register-based module
- Output Drive Capability: 20 Vp-p (50-Ohm load); 40 Vp-p (high-impedance load)
- DAC Resolution: 16-bit
- Signal Inputs: Two independent channels with pre-amplifier attenuators for independent level control
- Output Attenuation: Switchable 20-dB post attenuator
- Programming Interface: SCPI language
- VXIbus Interface: Standard VXIbus integration
Key Features
- Summing amplifier with independent input channel control
- Precision 16-bit DAC for programmable DC offsets and output levels
- Pre-amplifier attenuators enable independent signal scaling on each input
- Post-output attenuation for sum reduction without additional external components
- Register-based control architecture for deterministic operation in automated systems
Typical Applications
- Multi-signal conditioning and combination in test environments
- Programmable offset and scaling in data acquisition systems
- Signal summing with variable gain control
- DC bias and offset application in precision measurement setups
Compatibility & Integration Programs via SCPI with an Agilent E1406A Command Module or Agilent E1445A Arbitrary Function Generator. The E1446A operates as a servant module to the E1445A when paired with that generator. Standard VXIbus connectivity enables integration into existing modular test systems. This product is listed as Obsolete by Keysight.

Agilent / Keysight E1446A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E1446A. Calibration covers all module-specific parameters per manufacturer datasheet, output accuracy and linearity, frequency accuracy, and VXI register and trigger bus compliance. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight E1446A faults: relay contact wear, DAC/ADC drift, VXI backplane connector oxidation. Common faults include relay contact wear, DAC or ADC gain drift, and VXI backplane edge connector oxidation. Most modules are repaired at the component level with full post-repair verification in a C-size or D-size mainframe.
