Notes/Equations

1. Baseband Studio for waveform streaming is an Agilent product that contains elements of PC hardware and software that, when coupled with an Agilent PSG or ESG vector signal generator and a PC, provides a deep memory signal source needed for thorough testing early in the development process.
   The I/Q waveform data from a Baseband Studio file can be played using the Baseband studio for streaming UI directly on the ESG/PSG internal baseband generator DACs in a continuous fashion. This results in long, unique test signals, up to hours in length directly from the ESG/PSG analog I/Q and RF output ports.
   The CM_BB_StudioStreamRead component can be used to read data from a file format compatible with the Baseband Studio product in an ADS simulation. In addition, the CM_BB_StudioStreamRead and CM_BB_StudioStreamWrite components can be used to save and playback long I/Q sequences within ADS.
2. The component has two outputs: a data output pin for complex I/Q data and a control output pin for marker values. The number of outputs in the marker output pin is driven by the MarkerFormat parameter.
3. The MarkerFormat parameter specifies if the waveform data in the file is interpreted as 16-, 15-, or 14-bit data with 0, 2 or 4 markers are embedded in each data value respectively.
   zero Markers(16 Bit I,Q) - no output from the marker pin
   two Markers(15 Bit I,Q) - one complex output from marker pin in the form (Event1 − bit + j Event2 − bit)
   four Markers(14 Bit I,Q) - two complex outputs from marker pin in the form (Event1 − bit + jEvent2 − bit) and (Event3 − bit + jEvent4 − bit)
4. If the length of simulation is larger than the available data in the file, use the Periodic parameter to repeat the old data. If Periodic = YES, all data from the file is read and repeated. If Periodic = NO, the output is zero after all data is read.
5. If ControlSimulation = YES, the simulation runs until the last data in the waveform file is read.
