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.
