Acquiring point spectra

While acquiring point spectra, your sample will be moved to keep it in the x-ray focus as the monochromator changes its wavelength (unless you uncheck Advanced $\rightarrow$ Track ZSTG in Spectra). For this to work properly, you will have wanted to record the x-ray focus on the sample beforehand (see Sec. 2.8). Note that while STXM III could only acquire 512 points in a spectrum, in STXM V one can record any reasonable number of points.

People frequently use very long dwell times for acquiring spectra. Because we are recording a 100kHz reference clock signal with a 16 bit (actually 24, but we cut it down to 16) scaler, the dwell should not exceed 500ms (actually 655ms, but there needs to be room for fluctuations).
