MT Format Eye Diagram (complex)
Specifies a complex-valued waveform, divides it into segments, and displays those segments as plots on a waveform graph. This node determines the segment length based on the symbol rate and eye length parameters.
This node displays either the I or Q component of the input signal, depending on the selection you make on the I/Q parameter in MT Format Eye Diagram (complex).
Inputs/Outputs
waveform
Recovered modulated data for plotting as an eye diagram.
t0
Trigger (start) time of the Y array.
Default value: 0
dt
Time interval between data points in the Y array.
Default value: 1.0
Y
The complex-valued signal-only baseband modulated waveform. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.
symbol rate
The desired symbol rate, in hertz (Hz).
Default value: 1.0
eye length
Number of symbol periods on the horizontal scale of the eye diagram.
Default value: 1
I/Q
A value that indicates whether to generate I data or Q data to the eye diagram.
| I |
Generates in-phase (I) data. |
| Q |
Generates quadrature-phase (Q) data. |
Default value: I
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default value: No error
eye diagram
An array of waveform segments for eye diagram display. Each segment has a time length of (eye length × symbol period) seconds. Wire this parameter directly to a waveform graph.
t0
Trigger (start) time of the Y array.
Default value: 0
dt
Time interval between data values in the Y array.
Default value: 1.0
Y
The complex-valued signal-only baseband modulated waveform. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.
error out
Error information.
The node produces this output according to standard error behavior.
