Chapter 6MeasurementsAbout this chapterCanary’s measurement panels can be configured to display any combinationof measurements and parameters for each of the three signal views and forcorrelation plots. Over 80 individual measurements and parameters areavailable for display in the measurement panels. Measurements can betransferred from a measurement panel to the data log with a single mouseclick.The data log can then be saved in a variety of formats for easy export tostatistical, spreadsheet, word-processing, or other programs.This chapter first explains the basic operation of the measurement panels andshows how to configure panels to display the desired measurements. Tworeference sections then briefly describe each of the parameters andmeasurements available. The final section discusses how to transfermeasurements to the data logger and export of data to other applicationprograms.The measurement panelThe measurement panel can be displayed by selecting Measurement Panelfrom the Windows menu, or by typing Command-M. Selecting MeasurementPanel or typing Command-M (or clicking in the panel’s close box) while themeasurement panel is showing hides the panel.Canary provides separate measurement panels for waveform, spectrogram,and spectrum signal views, and for correlation functions. At any one time,only the measurement panel for the active pane (which may be one pane of asignal window or a correlation window) is displayed. When you switch panesby clicking on a different pane, the panel is rebuilt for the new active pane.The data that are displayed for each pane depend on how the panel has beenconfigured, as discussed in the section on “Configuring the measurementpanel” later in this chapter. In this manual, references to “the measurementpanel” mean whichever measurement panel is currently displayed.The measurement panel contains one or more cells that display either of twotypes of data, called parameters and measurements (Figure 6.1). Parameters,which are displayed in the upper row of the panel, are characteristics of anentire signal, view, or correlation, and are unaffected by the position of themouse pointer or the location of a selection. For example, parameters for thewaveform pane include signal duration and sampling rate. Measurements,which are displayed in the lower row of the panel, can be either pointmeasurements or range measurements. Point measurements refer to the locationof the mouse. As you move the mouse within the active pane, pointmeasurement cells are continually updated to reflect the mouse position. If themouse moves out of a pane’s plot area, point measurement cells display “--”.Canary 1.2 User’s Manual 87
