The Baseband table in the Carrier n node enables you to set the Frequency Offset and the carrier's Power levels.
The General parameters for the Library Waveform are described in General (Library Waveform).

2. Baseband |
|---|
| Timing Offset |
| Initial Phase |
Choices: AUTO | 30.72MHz | 61.44MHz | 92.16MHz | 122.88MHz | 153.60 MHz | 184.32 MHz
Default: AUTO
Displays the Baseband Sample Rate. The source waveform will be re-sampled to this sampling ratio.
Waveform Length is directly related to the Oversampling Ratio value selected. The higher the Oversampling Ratio, the larger the waveform.
View the Waveform Length, displayed in points. The length of waveform after re-sampled. This parameter is not editable.
Range: -76.8 MHz to 76.8 MHz
Default: 0.000000 Hz
Set the frequency offset for the carrier relative to the signal generator’s frequency setting.
The range of the parameter is coupled to the Baseband Sampling Rate and the max ARB Sample Clock of the connected signal generator.
| Maximum Arb Sample Clock (RF Bandwidth) | Maximum Frequency Offset |
|---|---|
| 75 MHz (60 MHz) | 15.36 MHz |
| 100 MHz (80 MHz) | 30.72 MHz |
| 125 MHz (100 MHz) | 46.08 MHz |
| 150 MHz (120 MHz) | 46.08 MHz |
| 200 MHz (160 MHz) | 76.8 MHz |
Range: -60.00 to 0.00 dB
Sets the carrier’s power relative to the signal generator’s amplitude setting.
Range: 0 to 100000
Default: 0
Sets the timing offset of the carrier with the number of base sampling duration (1/30.72MHz).
Range: 0 to 359 degrees
Set the initial phase of the carrier.
Range: 1 to 20
Set the filter ratio. This filter ratio is applied to the source waveform filter.
