This parameter sets oversampling ratio of waveform generation. This value is used when Auto Oversampling Ratio is Off.
The Total Sample Points value is automatically determined based on the oversampling ratio. Using a larger oversampling ratio result in a more completely filtered image, but also uses more waveform memory by increasing the number of waveform points. In the case where the System Bandwidth = 1.4MHz, Auto = 2, else Auto = 1.

Base Sampling Rate is a sampling rate without Oversampling Ratio (OSR).
There is a relation among Base Sampling Rate, OSR, Total Sample Points and Waveform Generation Length as follows.
Total Sample Points = Base Sampling Rate (MHz) x OSR x 1000 x Waveform Generation Length (ms)
Ex) System BW = 5MHz, OSR = 1 (Auto), Waveform Generation Length = 10 (ms) case:
Total Sample Points = 7.68 (MHz) x 1 x 1000 x 10 (ms) = 76800 (Points)
The software sets the Base Sampling Rate based on the System Bandwidth (BW) as follows:
System BW = 1.4 MHz, Base Sampling Rate = 1.92 MHz.
System BW = 3 MHz, Base Sampling Rate = 3.84 MHz.
System BW = 5 MHz, Base Sampling Rate = 7.68 MHz.
System BW = 10 MHz, Base Sampling Rate = 15.36 MHz.
System BW = 15 MHz, Base Sampling Rate = 23.04 MHz.
System BW = 20 MHz, Base Sampling Rate = 30.72 MHz.
For multi-carrier waveforms, the Base Sampling Rate = 30.72 MHz.

[Uplink TDD]
Sets the frequency offset for the carrier relative to the signal generator’s frequency setting.
The range of the parameter is coupled to the Oversampling Ratio, the Base Sampling Rate, the System Bandwidth and the max ARB Sample Clock of the connected signal generator.
Frequency Offset and Cell ID are always editable, even if Auto Carrier Aggregation Configuration is on.
In either case below (1 or 2), auto configuration is performed for Frequency Offset, Cell ID, Uplink Downlink Configuration, Special Subframe Configuration, and Cyclic Prefix.
When any of these actions are performed: Add Carrier, Delete Carrier or Change System BW, and the Auto Carrier Aggregation Configuration parameter is on.
When the Auto Carrier Aggregation Configuration parameter is changed from off to on.
Auto configuration sets Cell ID same as Component Carrier Index, and the parameters (Uplink Downlink Configuration, Special Subframe Configuration, and Cyclic Prefix) on the secondary cells same value of the primary cell as read-only parameter.
If Auto Carrier Aggregation Configuration is set to off, auto configuration does not work.

The cyclic prefix used with SC-FDMA modulation in LTE results in a discontinuity between SC-FDMA symbols. Windowing is used in the Signal Studio for 3GPP LTE software to reduce spurious signal generation between symbols caused by this discontinuity. Symbol Rolloff sets the windowing length in Basic Time Units. Adjusting the Symbol Rolloff Length can improve ACPR performance, however this may result in degraded EVM performance.
Basic Time Unit (Ts) = 1/(15000 x 2048) seconds

The Carrier Aggregation node holds the settings of carrier aggregation.
Sets the state of Auto Carrier Aggregation Configuration on or off.
Frequency Offset and Cell ID are always editable, even if Auto Carrier Aggregation Configuration is on.
In either case below (1 or 2), auto configuration is performed for Frequency Offset, Cell ID, Uplink Downlink Configuration, Special Subframe Configuration, and Cyclic Prefix.
When any of these actions are performed: Add Carrier, Delete Carrier or Change System BW, and the Auto Carrier Aggregation Configuration parameter is on.
When the Auto Carrier Aggregation Configuration parameter is changed from off to on.
Auto configuration sets Cell ID same as Component Carrier Index, and the parameters (Uplink Downlink Configuration, Special Subframe Configuration, and Cyclic Prefix) on the secondary cells same value of the primary cell as read-only parameter.
If Auto Carrier Aggregation Configuration is set to off, auto configuration does not work.
