Important Notes

  • It is NOT necessary to create an SMC measurement before performing a remote Phase Reference Cal. It is necessary when performed from the user interface.

  • Before A..09.90, port selection was made remotely by selecting connectors and Cal Kits for the ports to be included in the SOLT calibration. With A.09.90, port selection is made explicitly with the commands in this node.
