This option allows a series of pre-defined actions to be run through within the PHABRIX Sx using a script stored in internal memory. The command scripts option can be used to automatically step through a sequence of instrument states, controlling the generator, analyser and logging functions. If required the instrument will prompt the user before going onto a subsequent state. Applications include repeated test sequences as required by manufacturer Test Departments, R&D Departments, Systems Integrators and Commissioning/Support Engineers. A script requires a set of memories to configure the unit and then a script file which recalls those memories and specifies times and actions for each step. The process of creating a command script requires these two files to activate the sequence. Additionally a script can be created as a simple text file on a PC and then transferred to the unit via Ethernet and recalled at any time. A large number of named scripts and memories may co-exist within the instruments store to be recalled as required.
