27. used to uniquely identify each server Timing Type The timing type can be set to either master or slave If a server is set as a master it uses its own clock source as defined in the Clock Source column and output clock and trigger signals through the installed timing module If a server is set as a slave it gets the clock source from the installed timing module Location The label for identifying the location of each server it is not required and can be left blank Clock Source The clock source can be set as either internal or GPS and is only applicable to master timing type servers The timing type for slave chassis should match that of the master Note that GPS is not available on all timing modules 2 4 Data Export The Data Export utility converts acquired TDMS time or frequency files to CSV or DiAdem formatted files Exporting to DIAdem converts the unscaled binary data from voltage and IEPE sensor types to data scaled in engineering units This allows the data to be imported directly to DIAdem If the TDMS source is a folder all TDMS files in that folder are converted If a single file is selected only that file is converted The configuration information is written to a text file and the data is written to the selected format 2 5 Acquire Panel The Acquisition Panel includes Time Acquisition Frequency Acquisition and Signal Monitoring utilities The Acquisition panel also includes menus to update th
