Channel Bandwidth (TEDS)
Consistent with preset choice
25kHz, 50kHz,
100kHz, 150kHz (Normal Uplink, Normal Downlink, and Control Uplink)
25kHz
(Random Access)
specifies the bandwidth for your TEDS demodulation analysis: 25kHz, 50kHz, 100kHz, or 150kHz. See Analysis Subcarrier for more information. Since the channel bandwidth is selected prior to using the Preset To Standard button, there is no fixed default across slot formats.
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 feature a 25kHz channel bandwidth with 8 subcarriers, a 50kHz channel bandwidth with 16 subcarriers, a 100kHz channel bandwidth with 32 subcarriers, and a 150kHz channel bandwidth with 48 subcarriers, while the Random Access only applies to a 25kHz bandwidth with 8 subcarriers. See Slots and Symbols for more information.
