Better than 15ppm/year Accuracy The outstanding accuracy and stability of the 5018 is achieved by the use of a patented circuit. It incorporates a dedicated micro-processor to continually monitor the state of a bank of precision voltage references. The basic digital to analogue converter has 22 bit (0.25ppm) resolution. Linearity and temperature coefficient are compensated in software to better than 0.1ppm of full scale per degC. For the DC 2V/20V ranges noise is <1ppm (<1Hz) and short term stability <0.5ppm/day and <2ppm/month. An external 1000:1 screened attenuator is available as an option for very low noise AC output. Display Eight bright 7 segment LEDs are used to display the output with a bank of dot matrix LEDs to show units and other information. GPIB & RS232 These interfaces allow the 5018 to be connected to a PC and controlled by an external program such as Time Electronics’ EasyCal calibration software. EasyCal ATE Control Software A suite of programs that simplify and speed up automatic control of the 5018. If you have equipment or systems that need testing or setting up against specification, and the results stored and printed, EasyCal is the answer. Automating the process brings important benefits and provides increased speed and consistent results. Test reports are produced easily to ISO 9001 quality standards. EasyCal has the ability to control a wide range of GPIB & RS232 programmable instruments and comprehensive ATE systems can be configured to control a wide variety of applications. It has full read back capability and therefore can perform closed loop testing. Conditional tests can be configured to allow decision making to further enhance the usefulness. See the EasyCal data sheet for more information.
