Ametek / VTI Instruments / VXI Technology VM3616A 16-channel, 16-bit DAC/Waveform Generator

The Ametek VM3616A is a 16-channel, 16-bit Digital-to-Analog Converter and Waveform Generator designed for automated test equipment, process control, and data acquisition systems. This VXIbus C-size module integrates into the VMIP platform, enabling up to 48 DAC channels per slot through multi-module configurations. The instrument delivers precise analog signal generation across independent channels with three operational modes: Arbitrary Waveform Generation (AWG) with sophisticated looping and branching, FIFO streaming at up to 100 kSa/s, and static Normal mode for predefined values.

Technical Specifications

• Channels: 16 independent 16-bit DACs per module; scalable to 48 channels per VXIbus C-size slot


• Resolution: 16-bit


• Output Ranges: ±20 V and ±10 V


• AWG Data Capacity: Up to 4096 segments per waveform with looping up to one million cycles or continuous operation until triggered


• FIFO Throughput: 100 kSa/s maximum


• Timer Resolution: 100 ns (internal programmable clock)


• Normal Mode Storage: 512 predefined values per channel in RAM


• Interface: SCPI-compatible command set; message-based word serial and direct register access

Key Features

• Arbitrary Waveform Generation: Complex waveforms via segment linking and looping with synchronous or asynchronous advance modes


• Synchronized Channel Operation: All enabled channels synchronize in AWG mode with identical segment lengths


• Flexible Data Pacing: Internal timer, VXIbus TTL triggers, or front panel input


• Simultaneous Multi-Channel Updates: All 16 channels updatable with single command in Normal mode


• Independent Channel Control: Modify static output levels during scan operation without interruption

Typical Applications

• Automated test equipment (ATE) control systems


• Process control analog generation


• High-density data acquisition waveform synthesis


• Multi-channel arbitrary signal generation

Compatibility & Integration VXIbus module compliant; integrates with VMIP modular instrumentation platform for high-density configurations.
