GENESIS SPECTRUM USER MANUAL

Chapter 3Main Window Overview3.4 The Status BarThe status bar at the bottom of the screen displays important parameters and statusinformation. The information will change dynamically while the software is open. Whenthe system is active (i.e a spectrum is being collected) the counts per second and dead timewill be displayed in red. The following parameters are displayed:CPS- current gross count rate (fast-discriminator counts)DT%- dead time % (percentage of total time the spectrometer isprocessing or rejecting count data)Lsec- spectrum acquisition time expressed in live secondsCnts- counts in the channel under the cursorKeV- location of the cursorFS- the vertical full-scale value of the spectrum in countsAmpT: 40- If Auto Amp time is used this is the actual HW AmpTime.Det- detector typeRes- the detector resolution.3.5 The Spectrum Collection WindowThe Spectrum window displays the spectrum and the label given to the spectrum. Thebottom (x) axis is the energy expressed as keV and the full scale value shown in the statusbar is the vertical (y) axis in counts. The window is typically viewed with one spectrum inthe collection window. Multiple spectrum windows can be opened by selecting “New”from the file pull down menu. Multiple windows can be viewed in cascade or tiled formatby selecting the corresponding option in the “Window” pull down menu.3.6 Other Panel ViewsPanels for advanced features such as regions of interest, rate meter, calibration andmicroscope control (systems with column control) can be accessed through the “Setup”pull down menu. The microscope control panel can also be accessed from the toolbar (theright most icon). To return to the main Spectrum control panel click on thebutton.10 GENESIS Spectrum - User’s Manual
