Ametek / VTI Instruments / VXI Technology VT1586A-001 Rack Mount Terminal Panel with RF Filters

The Ametek VT1586A-001 is a rack-mount terminal panel that extends VXIbus instrument connections to remote measurement points. It supports up to 32 three-wire connections via SCSI interconnect cables, with integrated RF filtering and on-board temperature sensing for enhanced measurement accuracy.

Technical Specifications

Signal Conditioning

• Common-mode rejection ratio (CMRR): >100 dB from DC to >10 MHz


• Common-mode filtering: 3-winding transformers per channel, attenuation above 1 kHz


• Measurement bandwidth: Not limited by RF filters Temperature Sensing


• On-board thermistors: Three strategically positioned units


• Thermistor excitation: 122 µA current source (available from VT1413C or VT1415A modules)


• Excitation terminals: HI-I and LO-I


• Temperature compensation: Resolves gradients across panel length Connectivity


• Channel count: 32 three-wire connections


• Interface: VXIbus via SCSI interconnect cables


• Cable requirement: Two SCSI cables (16 channels each) for full 32-channel operation


• Cable inclusion: Not supplied; must be procured separately

Key Features

• RF filtering option (-001 designation) with 3-winding common-mode transformers eliminates common-mode interference without sacrificing bandwidth


• Integrated thermistors enable temperature-compensated measurements across the full panel length


• Modular SCSI connectivity supports scalable channel expansion


• Supports DC through >10 MHz signal paths with excellent common-mode rejection

Typical Applications

• Extended signal routing for VXIbus data acquisition systems


• Remote multiplexing with common-mode noise rejection


• Temperature-compensated measurement chains


• High-speed analog signal distribution in distributed test configurations

Compatibility & Integration The VT1586A-001 requires specific Terminal Modules for operation: VT1413C High Speed A/D Converter or VT1415A Algorithmic Closed Loop Controller. The 122 µA excitation current for on-board thermistors is supplied only by these modules to channels 00–31. This panel is equivalent to the Keysight/Agilent E1586A.
