FETC:XAXI? {trace,
domain, units,
decimate}
Retrieves the X-axis data for the specified variables:
Trace can be A, B, C, D or E.
Domain = 0 for the time domain, 1 for frequency domain.
Units for the time domain (0):
0 = time (ns)
1 = length (m)
2 = length (ft)
3 = length (in)
4 = length (mm)
Units for the frequency domain (1):
0 = wavelength (nm)
1 = frequency (GHz)
2 = frequency (THz).
Decimate: 1 = use decimation, 0 = return all points.
