Description
The VLW-1220 reliably generates very long high-speed waveforms which is nearly impossible to achieve in a standard PC with analog output board combination. It provides advanced triggering for nearly any synchronization requirement. This unit saves time and money by avoiding the research, development, debugging, and testing of a custom system. It focuses on high quality results with minimal hassles.
In a typical application the VLW-1220 can be set up to record a process using its two analog inputs. The recording can be synchronized using external clock and trigger to precisely record position/value measurements. New waveforms may also be created without using the analog input recording feature.
Output playback is fast and reliable. In some cases the outputs may be played out at full speed for time saving during verification, then played at a slower normal speed for final production. For a long term process, this time savings can really pay off.
VLW-1220 Product Specifications
Analog Output
- 2 channels (Expansion options available), BNC connectors
- 12-bit D/A, +/- 5V, 2 mA (optional +/- 10V)
- 800 Ksamples/s per channel (Optional 16-bit D/A, 400 Ksamples/s per channel)
- External trigger to begin output stream, +5V TTL rising edge pulse, BNC connector
- External clock to update all channels on each +5V TTL rising edge pulse, BNC connector
- Internal clock mode with the output update time selectable in increments of 0.1 microseconds (1.2us, 1.3us, 1.4us, etc.)
- External arm input. This allows a data output record of predefined length to be cycled until the arm signal triggers a transition to the next record. BNC connector.
- Optional additional digital I/O and trigger modes available according to your specification
Analog Input
- 2 channels (Expansion options available), BNC connectors
