Analysis Subcarrier (TEDS)
(See Using Standard Setups/Presets)
-24 to +24, choices dimmed if not applicable due to Channel Bandwidth setting.
is used to select the sub-carrrier for your TEDS demodulation analysis. For example, you can view a particular subcarrier in your constellation diagram. See TEDS Subcarriers to learn more.
TEDS is based on variable subcarrier/channel bandwidths of 25, 50, 100, and 150kHz, with burst uplink and continuous downlink slot formats. In particular, the Normal Downlink, Normal Uplink, and Control Uplink slot formats can use a 25kHz bandwidth, 50kHz bandwidth, 100kHz bandwidth, or 150kHz bandwidth, while the Random Access slot format can only use a 25kHz bandwidth.
The number of subcarriers in a signal depends on the channel bandwidth selected. The table below shows the number of subcarriers for each channel bandwidth.
