The method uses known Standards, Opens, Shorts and Loads. The Load can be either a sliding or a fixed broadband load. The Kits supplied, can be divided into three groups: The Standard Calibration Kit, the Expanded Calibration Kit, and the Professional Calibration Kit. The Instrument Cases for all three of these Calibration Kits are identical. The customer may start with the Standard Calibration Kit and fill the empty spots at a later stage, to end up with an Expanded, or even the Professional Calibration Kit.The Kits, as suggested for Hewlett Packard and Wiltron, do differ slightly in the number of components supplied, as necessary for the different calibration sequences.
It contains all the components needed for calibration in the subject connector series, Opens, Shorts, Broadband Loads, and the Software Configuration Medium.
Besides the components supplied with the Standard Calibration Kit, a set of interface gauges for center conductor location dimensions, calibration blocks for zeroing the gauges, wrenches, and a torque wrench are added.
Additional to the components supplied with the Expanded Calibration Kit, the sets of interface gauges and calibration blocks are completed for measuring further also certain critical outer conductor dimensions. A set of thread limit gauges for checking the connector and coupling nut threads is supplied as well. Four empty spaces can be filled with optional adapters, individually to be specified.
The most important Components of the Calibration Kits are the Calibration Standards. A Disc will be supplied, carrying data on the properties of the Calibration Standards. The disc is ready to be used on the Vector Network Analyzers of Hewlett Packard and Wiltron.
But also other components will be needed during testing and therefore be included in the Kit as well, such as precision adapters, torque wrenches, regular wrenches, as needed for any hex supplied with the components in the calibration kit. A set of precision gauges will be included, for checking the interfaces of the devices before test.
Before testing any device, the interfaces of the connectors have to be checked to ensure that they meet the appropriate specification. Protruding interfaces will damage the mating connector. Interfaces that are recessed below the allowed level will lead to useless test results.
For proper test results and long life of the connectors the rules need to be obeyed. For each individual connector series a torque has been specified, a torque that ensures proper mating conditions, repeatable electrical performance and guarantees mechanically a long life of the connectors. Using a Torque Wrench guarantees that the connection is not too loose, it also ensures that the connection is not too tight, preventing possible connector damage and impaired electrical performance. Using the Torque Wrench also assures that all connections are equally tight, each time.
