 |
swept sine task in specifies the swept-sine parameters.
 | Note Do not modify the swept sine task in values. |
|
|
swept sine measurements specifies the swept-sine measurements to perform.
|
|
view defines how the different results from this VI are returned.
view allows you to choose whether magnitude results are displayed in dB, phase results are unwrapped, and phase results are converted from radians to degrees.
 |
dB On specifies if results are expressed in decibels. The default is TRUE.
|
|
unwrap phase specifies whether to unwrap the phase. Unwrapping eliminates discontinuities that have an absolute value greater than pi. The default is FALSE, meaning the phase is not unwrapped.
When unwrap phase is TRUE, the phase is unwrapped.
|
|
convert to degree specifies whether the phase results are converted from radians to degrees. The default is FALSE, which means that results are expressed in radians.
|
|
 |
error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use exception control to treat what is normally an error as no error or to treat a warning as an error. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
|
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
|
 |
code is the error or warning code. The default is 0.
If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
|
 |
source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
|
|
 |
magnitude unit label returns the unit label for the magnitude spectrum.
|
|
phase unit label returns the unit label for the phase spectrum.
|
 |
swept sine task out contains the swept-sine parameters.
|
|
dup swept sine measurements returns swept sine measurements unchanged.
|
|
imaginary vs real (Nyquist plot) returns the real and imaginary parts of the frequency response function. Plotting imaginary vs real (Nyquist plot) on an XY graph results in the Nyquist plot.
 |
Re [FRF] returns the real part of the frequency response function.
|
|
Im [FRF] returns the imaginary part of the frequency response function.
|
|
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.
 |
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
|
 |
code is the error or warning code.
If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
|
|
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
|
|
|
phase returns the phase of the frequency response function. You can connect this output to an XY graph.
|
frequency returns the frequency, in hertz, of the fundamental tone at each test frequency.
|
|
phase returns the phase of the frequency response.
|
|
|
magnitude returns the magnitude of the frequency response function. You can connect this output to an XY graph.
|
frequency returns the frequency, in hertz, of the fundamental tone at each test frequency.
|
|
magnitude returns the magnitude of the frequency response at each test frequency.
