Setting the Channel Standard
You can specify one of the recognized GSM or EDGE standards for your measurements.
When you select your Channel Standard, the Start and Stop channels are automatically set to valid channels within the selected band only if your Units are set to Chan. If your Units are set to Freq, the Start and Stop Frequencies will not change from your current settings. For details on setting Units, see "Setting the Units of Measure for the Graphical Display"
