Saluki S3332 series handheld spectrum analyzer has USB, LAN or remote interface. User can control spectrum analyzer by these interface. In the previous article, we have introduced the SCPI programme and basic commands. In this section, we show how to use SCIP programme to build the calculate subsystem.
