Using Standard Setups/Presets (TEDS)

Click the Preset To Standard button to choose from the following preset standard formats:

Preset to Standard - Normal Uplink

After selecting Preset to Standard - Normal Uplink, the analyzer automatically enters the TEDS demodulation parameters appearing in the following table:
