ATE Calibration Robot - High Accuracy

High frequency measurements, high pin densities, and large test heads, demand a High Accuracy Calibration Robot.

The Calibration robot is used in conjunction with an oscilloscope, TDR or TDM instrument to validate tester signal performance or to perform a calibration at the test head. Commanded by the tester the robot automatically moves the probe tip to the desire DIB pad locations. The measured signal always travels though the same cable path to maximize signal repeatability. Stepper motors and a custom drive keep the system electrically quiet while recording measurements. A stiff structure and mapped lead screws insure a high positional accuracy of the probe.

Robots are customized to interface with specific ATE models. Customization enables us to accommodate the different communication and mechanical interface requirements of the testers. A variety of probe types are supported.
