Page 63: Complex Modulation Tab
M8190A User Interface 2.11 Complex Modulation Tab Use this tab to create baseband and IF/RF digitally modulated signals. User-defined corrections may be applied to signals to compensate for (or emulate) instrument, interconnections and channel linear distortions. The complex modulation tab allows you to generate signals for both direct conversion and external/internal up-converter (IQ) modes.
Page 64 M8190A User Interface Figure 2-13: Complex Modulation Only relevant parameters and edition fields are shown in the GUI at any time depending on the selected generation mode (Direct/Up-converter) and modulation scheme. Waveform Destination Section  Generate Baseband Data It is always seleced while in up-converter modes. If checked while in direct mode, it will assign the I (In-phase) component to Channel 1 and the Q (Quadrature) component to Channel 2.
Page 65 M8190A User Interface  Channel Independent checkboxes allow the definition of waveforms for Channel 1, Channel 2, or both. One of the boxes will be always checked and checking both is only possible when both channels are coupled (see Channel Coupling control in Clock Tab).
Page 66 M8190A User Interface  Alpha / BT The meaning and labeling of this edition field depends on the selected baseband filter. For “Nyquist” filters (Raised Cosine and Square Root of Raised Cosine) it is the ‘Alpha’ parameter (or roll-off factor) of the filter. For Gaussian filters it is the BT (Bandwidth/symbol period product) parameter.
Page 67 M8190A User Interface Scaling Section  DAC Max Waveforms may occupy a limited range of the DAC’s full scale. This parameter sets the maximum level. If set to a lower level than DAC Min, this will be automatically set to the same level. Acceptable range for this parameter is -1/+1, being the full dynamic range of the instrument’s DAC.
Page 68 M8190A User Interface Custom Modulation File Format A custom modulation file is an ASCII delimited file including all the information required to define a single carrier modulated signal based in quadrature (IQ) modulation. The file must be composed of a header including a series of lines with identifiers and parameters, and a list of numerical correction factors.
Page 69 M8190A User Interface The following example illustrates a simple example of a 3 bit per symbol QAM8 modulation with a particular constellation. #3 // MyModulationFile // Inner symbols 2.0, 0.0 0.0, -2.0 -2.0, 0.0 0.0, 2.0 // Outer symbols 3.0, 3.0 -3.0, 3.0...

Page 74 M8190A User Interface  Data Columns It shows the internal organization of the file regarding waveforms. It can show from one column (Y1) up to 4 (Y1, Y2, Y3*, Y4*). Although files with more than 2 columns are reported correctly, only the first two columns (Y1, Y2) are imported and processed.
Page 75 M8190A User Interface  Output_SR: The user-defined output sampling rate will be used to calculate the best value for the output record length being a multiple of the granularity for the current DAC mode according to the time window of the input signal.
Page 76 M8190A User Interface  Source Sample Rate The speed at which samples in the input waveform are sampled. It can be set by typing a valid value unless the "Use As Source Sample Rate" checkbox is checked. In this particular case, the sampling rate information contained in the input waveform file will be always used.

Since the M8190A software version 3.0, it is possible to modify the content of the sample memory when having selected one of the dynamic modes. Therefore, all segments or sequences that are currently not in use can be changed in run mode.

The hardware or software is not able to check this limitation. Obeying this rule is the responsibility of the user. In order to meet this rule, the user can query the segment number that is currently played by the M8190A. The dynamic modes have some limitations. The main problem for streaming applications is the fact that a pre-defined timing relationship is not always guaranteed when switching from one sequence to another sequence.
