This topic describes the Signal Optimizer's default Favorite Settings for a Custom IQ signal format.
Enter an alpha-numeric waveform file name. The name can include spaces and some special characters: _ $ & # + - [ ]. The maximum name length is 22 characters for non-Windows based instruments (e.g., N5182A, etc.), and 150 characters for Windows based instruments. (If you enter a name with more than the maximum name length, the software truncates the name to the length when you click outside of the cell.)
Enter an alpha-numeric comment of up to 32 characters. The comment resides in the file header and can include spaces and special characters.
Enter the number of frames included in the waveform.
Range: 1-300
Enter the oversampling ratio of the waveform. The Total Sample Points is automatically determined based on the oversampling ratio.
Range: 2-16
Enable or disable the mirror spectrum for the waveform.
Display the number of sample points in the waveform. This value is read-only and will be automatically updated with waveform setting change. Waveform length is directly related to the oversampling ratio value selected. (Increasing the oversampling ratio increases the total sample points.)
Display the waveform length in seconds. This value is read-only and will be automatically updated with waveform setting change.
Display the sample rate of the signal. This value is read-only and will be autotmaically calculated from symbol rate and over sampling rate.
Selects type of the modulation for the Signal.
Choices: ASK & PSK & QAM | FSK | SOQPSK | ARTM Multi-h CPM
Enter the symbol rate of the signal.
Range: 1k-4Gsa/sec.
Select the filter type to be applied to the waveform.
Choices: Low Pass | Gaussian | Root Nyquist | Nyquist | Rectangle | APCO25 HDQPSK | Half Sine | User Defined
Enter the Alpha factor of the Root Nyquist or Nyquist filter
Range: 0.01-1.0
Enter the BT value of the Gaussian Filter
Range: 0.1-1.0
Enter the bandwidth for low pass filter
Range: 1kHz-Sample Rate
Enter the filter length in symbols.
Range: 1-2048
Selects the type of the segment.
Choices: Data | Idle
Set the length of the segment in number of modulated symbols. The total number of symbols should be greater than the length of filter.
Range: 1 - 100000
Selects data type used as payload of the segment.
Choices: PN9 | PN15 | PN23 | Pattern | From User File
Enter the payload pattern up to 128 kbits.
Enter the file name to load for user-defined payload data.
Selects predefined constellation for the segment.
Choices: OOK | 2ASK | 4ASK | 8ASK | BPSK | QPSK | 8PSK | 16QAM | 32QAM | 64QAM | 128QAM | 256QAM | 512QAM | 1024QAM | 2048QAM | 4096QAM
