Ametek / VTI Instruments / VXI Technology VT1413C 64-Channel Scanning A/D Converter

The Ametek VT1413C is a C-size, single-slot VXI module that delivers 64-channel scanning analog-to-digital conversion for data acquisition and computer-aided test systems. Operating at 16-bit resolution with 0.01% reading accuracy, this register-based converter handles scanning rates up to 100 kSa/s (divided by active channels) and stores data in a 64 kSample dual-ported FIFO buffer for rapid transfers to the controller.

Technical Specifications

• Resolution: 16 bits (including sign)


• Channels: 64-channel scanning configuration


• Sampling Rate: Maximum 100 kSa/s, divided by number of active channels (1–64)


• Memory: 64 kSample dual-ported FIFO buffer


• Accuracy: 0.01% of reading per single sample; overall measurement accuracy depends on installed SCP module


• Input Impedance: 100 mΩ differential (SCP input impedance)


• Drift Error: 10 µV/°C ÷ SCP gain per °C change from CAL:ZERO temperature (after 5-minute stabilization)


• Input Range: Basic ±16 V full-scale with auto-ranging gains (x1, x4, x16, x64, x256); extended to 60 V with VT1513A attenuator SCP

Key Features

• Programmable scanning modes with flexible sequencing and auto-advance capability


• Automatic self-calibration routines; periodic calibration via external voltage standard


• Multifunctional measurement within individual scans: DC voltage, temperature, resistance, strain


• Real-time current value table for live monitoring


• Support for up to eight Signal Conditioning Plug-on (SCP) daughter boards - one per eight channels


• Optional terminal blocks: QUIC (Option 013) or screw connectors (Option 011)

Typical Applications Data acquisition systems requiring simultaneous multi-channel sampling, thermal and strain monitoring, automated test benches, and laboratory instrumentation where signal conditioning and range flexibility are essential.

Compatibility & Integration Mounts in any VXI mainframe supporting C-size, single-slot register-based modules. Scalable via SCP daughter boards, each offering buffering, filtering, amplification, sample-and-hold, or bridge excitation functions. Specific measurement specifications determined by selected SCP modules.
