Diagonal Measurement Kit
10768A
Mechanical Calibration Kit
The Keysight 10768A Diagonal Measurement Kit is designed for use with the Keysight 5530 Laser Calibration System. It allows linear measurements to be made on the four body diagonals of a machine tool's working volume. These measurements document the machine's capability and quickly perform a complete check of volumetric positioning performance. In addition, long-term drift tests can be performed over hours or days, showing possible effects of temperature on geometry.

RF Electronic Calibration Module (ECal), DC/300 KHz To 9 GHz, 3.5 Mm, 2 Port
85093D
Electronic Calibration Module
The Keysight 85093D RF electronic calibration (ECal) module makes the calibration of vector network analyzers fast, easy, and accurate. ECal is a precision, single-connection calibration technique for your vector network analyzer. Performing a full two-port calibration takes less than half the time and a number of connections using ECal versus mechanical calibration kits. Furthermore, the accuracy of the calibration is comparable between electronic and mechanical methods. Traditional mechanical calibrations require intensive operator interaction, which is prone to errors. With ECal, the operator simply connects the ECal module to the network analyzer and the software controls the rest.
