This set of checkboxes specifies the set of measurements to be made during the analysis interval.
For the particular Radio Standard that has been selected for the current acquisition, some measurements will be available and others will be grayed out. Only the first four measurements are available in all cases. With the standard set to NONE, as shown above, those four are the only available measurements. For other standards, other combinations of measurements are available. For example, compare the measurements for the EDGE and C2K standards, as illustrated below..
As you select measurements in the checkbox, the Meas Bitmap field in the Analysis Step Table is automatically updated. The combination of measurements you have selected is converted to a hexadecimal number; this is used as a sequence parameter which tells the test set's analyzer which measurements to make for this analysis interval.
If the analysis step table includes multiple rows (representing multiple analysis intervals), selections made using the checkbox apply only to the currently selected row. (To select a different row, click on it so that it is highlighted.)
