Validator comes with a breakout board which can be used to translate digital levels up or down. The breakout board can also be used to mate digital channels to a custom connector.
Validator comes with a suite of sample patterns. Out of the box, Validator can drive SPI patterns or create arbitrary analog waveforms with simple parameter data entry. A one time investment in creative worksheet design can create easy to use setups for future time-and-again requirements.
Validator utilizes a 72 bit wide fast access memory that stores up to 4,096 lines of pattern. The memory can be clocked by the internal 24 Mhz oscillator or by an external clock. The external clock can be DC to 50Mhz. Memory is loaded via the USB connection.
The pattern controller looks for commands at each line during pattern execution. The pattern can jump, pause, step, conditional jump if fail, and stop on fail.
Digital IO can be programmed at each line to be either output or input with a weak pulldown. The system clock can be output any digital channel. Any input can be tested to be One or Zero at any line. IO outputs 3.3V levels. The Breakout Board has provision to translate IO to anywhere from 1.6V to 5V.
The DACs are 10 bit each and can move 10V per microsecond. Their range is -10V to +10V.
Validator 1 will operate standalone with a 5V supply or from a USB connection. If standalone, the last downloaded pattern is available in nonvolatile memory for load and execution.
Validator 1 is 6.4 inches wide by 5.25 inches deep (excluding BNC) and 1.4 inches high. It weighs 12 oz.
Designed and assembled in the USA.
Validator ships with a memory stick loaded with the host application, “Validator1_Host”. Executing the application brings up the Control Panel which allows selection of the pattern to download to the Validator box. The Control Panel also exchanges control and status information with the Validator box.
Validator downloads from a CSV file that must be prepared in a standard format. A CSV file may be created by a variety of means. Excel or Calc may be most expedient. Standard format Excel spreadsheets are provided on the memory stick. Start with one of the sample patterns and enter Setup data and Line data. See both the User Guide and Guide to Using Sample Patterns included on the memory stick.
All files available on the memory stick are also available at the website.

Using Validator 1
Connect the USB cable to the Validator. Double click “Validator1_Host” in a Windows environment and use the Control Panel to download the saved CSV file Pattern.
Once downloaded, Validator retains the last program in nonvolatile memory. This allows unplugging the computer and taking the tester to the lab where any 5V supply can be the power source.
After download, the Ready light is on and the Validator is ready to run the pattern.
Control the pattern from either the host computer or use the buttons on the box.
After powering down and back up again, reload the pattern using the Load button on the box or load a new pattern from the Control Panel.
Refer to the User Guide and the Guide to Using Sample Patterns to discover all the options for driving your bench top setup.
