AT5600 Calibration.

Overview of the AT5600 Calibration & AT5600 Verification Processes.

The AT5600 is calibrated using a system similar the AT3600 + ATi, however it is a totally separate system so the existing AT CAL FIXTURE will not be able to calibrate the new AT5600.
Many of the principles are the same, and the below gives an overview of how the system operates, and how traceability to external standards is obtained.

a. The AT5600 is calibrated using a calibration fixture fitted with high stability reference impedances.

This process is performed using controlled voltech software which is documented on the calibration certificate

b. These impedances are characterised using a reference LCR meter (Keysight E4980A) and a precision multimeter (Keysight 3458A). this characterisation consists of 850 software controlled measurements between 20 Hz and 3 MHz

c.The reference LCR meter and precision multimeter are calibrated and verified at the manufacturers recommended interval using an accredited ISO 17025 calibration authority, who issue calibration certificates for these instruments.

a. The calibrated AT5600 is then thermally cycled in a chamber, cooled, and then verified using a verification fixture fitted with high stability reference components.

b. This verification fixture uses components that are significantly different to the components used on the calibration fixture to minimize the possibility of a calibration error being wrongly verified.

c. These impedances are also independently characterized and verified as described above in 1b and 1c

a. The calibration certificate serves to verify that calibration and verification has taken place.

b. It also summarizes the results of verification, and details the traceable standards used in these processes
