MT IQ to XY Graph VI

LabView Analog Modulation

MT IQ to XY Graph VI

Formats I/Q data for plotting on a LabVIEW XY graph. This VI extracts the I and Q data into two arrays (X and Y, respectively), which are bundled into the I vs. Q graph cluster for display on a LabVIEW front panel graph. To place a formatted XY graph on your LabVIEW front panel, right-click the I vs. Q graph output terminal and select Create┬╗Indicator.

IQ data (complex) in specifies the baseband (downconverted) time-domain data for representation on the XY graph.

t0 specifies the trigger (start) time of the acquired signal.

cdbl.gif

dt specifies the time interval between data points in the signal data.

Y specifies the complex-valued time-domain data array. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.

error in (no error) accepts error information wired from previously called VIs. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.

status is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.

code identifies the error or warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.

cstr.gif

source describes the origin of the error or warning. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.

IQ data (complex) out returns the baseband (downconverted) time-domain data. This VI does not modify this data, so this parameter is identical to the IQ data (complex) in parameter.

t0 returns the trigger (start) time of the acquired signal.

dt returns the time interval between data points in the acquired signal. The I/Q sampling rate is the reciprocal of this value.

i1dcdb.gif

Y returns the complex-valued time-domain data array. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.

icclst.gif

I vs. Q graph returns the XY graph indicator. The X axis contains I data and the Y axis contains Q data.

error out passes error or warning information out of a VI to be used by other VIs. Right-click the front panel error out indicator and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.
