Using Standard Setups/Presets (1xEV-DO)
Lets you select a 1xEV-DO standard preset configuration. When you select a standard preset, the VSA automatically sets the parameters shown in the following table:
-
1xEV-DO reverse link signal
-
1xEV-DO forward link signal
The 1xEV-DO Demodulator must be selected before these Standard Presets are available.
