Dear All，
I have an oscilloscope, model NI PXIe-5160 (2CH), and now I want to program C # to obtain the time difference between the rising and falling edges of wavelength changes, as shown in the attached images. When using the Instrument software, two lines C1 and C2 can be used for measurement, but they are not available in the NET program.May I know which methods are available to measure the difference between these two times?
In addition, what are the functions of LowReference, MiddleReference, and HighReference? I didn't understand them even after reading the documentation. Other oscilloscope devices do not have this function. If set according to default values, measurement errors will occur. Thank you！
