Using Standard Setups/Presets (TEDS)

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

Normal Uplink (25kHz, 50kHz, 100kHz, 150kHz)
Normal Downlink (25kHz, 50kHz, 100kHz, 150kHz)
Random Access (25kHz)
Control Uplink (25kHz, 50kHz, 100kHz, 150kHz)
The Channel Bandwidth needs to be selected before the Preset to Standard button is clicked. The preset parameters, including frequency span, ACP Adjacent Channel Power: The power from a modulated communications channel that leaks into an adjacent channel. This leakage is usually specified as a ratio to the power in the main channel, but is sometimes an absolute power. Offset, and ACP Bandwidth, are specific to the selected channel bandwidth (as well as the selected slot format).
Some parameters may need to be changed after a Preset to Standard, for example, Modulation Type.
