1. 4 3 Timestamp A common timestamp is used throughout Edgar to keep all files synchronized The timestamp is the link between all the files Different timestamp sources are offered IRIG B INS synchronized network time and manual time These options can be set from the Edgar Preferences window under the Timestamp tab 4 3 1 INS Inertial Navigation System In the INS timestamp mode as soon Edgar knows that the INS has a lock on a satellite it synchronizes its time with the one on the Annotator Then the timestamp is managed by the Annotator at each scan Since the INS system only provides the time in seconds since midnight of this week s Sunday the week number and year is taken from the system running Edgar So when you are in INS timestamp mode you should always verify the system date and time of your computer Page 9 Edgar User Manual LR Tech inc lonetrics Version 1 1 0 August 2010 If the time cannot be taken from the INS because it hasn t been able to connect to any satellites yet the timestamp of the Annotator is synchronized with the one of the system running Edgar This is another good reason to have a valid system time on your computer 4 3 2 IRIG B Annotator time is synchronized automatically to an external IRIG B input 4 3 3 Network Time When in Auto time mode there is an option available to synchronize the Annotator timestamp with a network time server rather than using the time of the sy2. You can also manage alert levels for each sensor independently and log those alerts in a CSV Comma Separated Value file for further access You can even go one step further and log in a separate file all the sensor readings synchronized with an acquisition This way you can always know what is happening with your instrument and be ready to troubleshoot if something goes wrong In order to know at any time the current status of the housekeeping and without having to open the live sensor feed window a colored chip is present at the top right corner of the screen when you open Edgar with the Housekeeping module activated The color chip displays the current higher level of alert of the module If you want to open the live sensor feed quickly you can double click the color chip 8 1 Configuring Housekeeping You can access the Housekeeping module configuration from the Edgar Preferences window under the tab Housekeeping If you want to activate the module the Enable the Housekeeping module check box must be checked Once it is checked the module will start at each Edgar startup One of the strengths of this module is its configuration file Since all the configurations of the module are stored in a easy to read and share XML file you can use it with all your computers and change the file when you change the instrument used Specify the housekeeping configuration file in the configuration window Should you need a new one there is a

9. bit floating point data the preamp gain is factored in prior to writing to disk The raw 16 bit sample values are scaled by the appropriate constant based on the preamp gain setting to generate a 32 bit float It is the scaled floats in this case that are actually written to disk Since the Excel annotation file generated by Edgar contains the preamp gain setting for each scan it is possible to work backwards and arrive at the raw sample values if needed The default raw data output format is 16 bit fixed point In this output mode the subheader exponent field is set so that data for a preamp gain of 128 is stored with a multiplier of 1 exponent field is 16 and data collected at a gain of 64 is stored with a multiplier of 2 exponent is 17 and so on This makes it possible to determine the detector preamp gain setting directly from the subheader exponent field using the following table 23 1 22 2 21 4 20 8 19 16 18 32 17 64 16 128 5 6 2 MatLab Mat File Format Like other scientific data analysis software MathWorks Matlab has its own proprietary file format for storing data MAT files are Matlab s file format for saving and loading any data available in a Matlab workspace Once you open such a file in MatLab any data stored in it will be available as matrix arrays in your workspace Whenever you acquire process display manipulate or export data from Edgar you have the option to output the fil
