Using Standard Setups/Presets (TEDS)

Click the 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 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.

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:
