Missing LabVIEW Modulation Toolkit Examples for the NI PXI-5660 RF Vector Signal Analyzer I have the LabVIEW Modulation Toolkit 3.1. I recently upgraded the NI-RFSA driver to version 2.0 or later, but I can only find a few of the NI 5660 example programs I expected to see. Where are the others?

No se Encuentran los Ejemplos de LabVIEW Modulation Toolkit para PXI-5660 Vector Signal Analyzer Tengo instalado LabVIEW Modulation Toolkit 3.1. Recientemente actualicé el driver NI-RFSA a la versión 2.0 (o posterior), pero ahora no encuentro mas que un par de ejemplos del ni5660. ¿Dónde se encuentran los otros?

THD and THD+N Accuracy with Respect to Block Size I am performing a Total Harmonic Distortion plus Noise (THD+N) measurement using the Sound and Vibration Toolset in LabVIEW, and it appears that the measurement is more accurate if I take more samples (larger block size). What block size do I need in order to guarentee a certain degree of URL: http://digital.ni.com/public.nsf/allkb/E8837ACA91721DFB86257279007A8D7B

Error -1947 When Running Swept Sine in the Sound & Vibration Toolkit I am getting error -1947 when running the example SVXMPL_Swept Sine FRF (DAQmx).vi (or other swept sine code). My application runs without error if I choose a smaller stop frequency for the sweep. Why am I unable to select higher values for the stop frequency, so long as they are below the URL: http://digital.ni.com/public.nsf/allkb/A728199A8B7E77FA86257144000F72A2

当运行声音振动工具包里的Swept Sine时提示错误-1947 当我在运行SVXMPL_Swept Sine FRF (DAQmx).vi（或其它的扫频）范例的时候，会碰到1947的错误。当我选择一个较低的扫频终止频率时，我的程序不会报错，为什么我的终止频率不可以设置的更高呢？但是他们也确实也是低于Nyquist频率的啊！ URL: http://digital.ni.com/public.nsf/allkb/23FC00F5456EF6898625735F00418C71
