San Francisco, Calif.Here's a new board-level four-channel analog and digital waveform generator plug-in that can let you create arbitrary waveshapes that are synchronized with logic-level outputs. This 6U-sized VME bus board, dubbed the V350, should find utility in control systems, radar simulation systems, and COTS (commercial off-the-shelf) military applications, to name just a few. In those applications it can perform 40-Mssample/s waveform synthesis.
Available from Highland Technology, the V350's four waveform generators are each capable of generating both one 12-bit analog waveform and up to four digital TTL-compatible outputs. The board's four arbitrary waveform outputs can be set to as much as 10-V into 50-ohm loads, delivering 100-mA max. Analog bandwidth is rated at 1-MHz full power (minimum).
Channels can also operate independently or synchronized within a module. Each channel uses 1-Mword of waveform memory that's controlled through a 512-block command table. The table includes Play, Delay, Wait, and Stop commands, as well as a conditional jump, and flag control.
Notably, the V350 generator builds on Highland's existing ARB (arbitrary waveform generator) to simulate complex waveform sequences at very high speeds. It does that by scanning sequential data points stored in user-loadable memory, with outputs processed by DACVs (digital-to-analog converters), smoothing filters, and output amplifiers. The process is under the control of a so-called micro-engine architecture.
Multiple Module Sync
Outputs can also be synced across multiple modules, with operation at a 40-MHz rate or programmed sub-multiples. An option permits waveform generation to be synchronous to an external trigger, without jitter resulting from quantization to a local clock.
Outputs are delivers through standard connectors mounted on the board's front panel. Connectors are SMA types for waveform outputs, pulse outputs, and clock output. A DB-9 female connector is used for the board's two sync outputs and four logic inputs (other connectors are available as options).
The V350 also features Self-test and Demo modes to let you make quick evaluations and verifications of test data.
The V350 Function Generator is available in both a standard version, and in a conformal-coated wide-temperature range COTS version.
