FETC:GSTR?
{domain,
graphType, xUnits}
Retrieves the graph title or name, the Y-axis label, and the X-
axis label for the specified domain, graphType, and xUnits.
Domain = 0 for the time domain, 1 for frequency domain.
GraphType values for the time domain (0):
0 = Amplitude
1 = Linear Amplitude
2 = Polarization States
3 = Phase Derivative
4 = Amplitude (dB)
5 = Spectral Shift (only on some instruments)
6 = Temporal Shift (only on some instruments)
7 = Strain (only on some instruments)
8 = Temporal Shift (only on some instruments)
GraphType values for the frequency domain (1):
0 = Return Loss
1 = Linear Amplitude
2 = Polarization States
3 = Group Delay
xUnits values for the time domain (0):
0 = time (ns)
1 = length (m)
2 = length (ft)
3 = length (in)
4 = length (mm)
xUnits for the frequency domain (1):
0 = wavelength (nm)
1 = frequency (GHz)
2 = frequency (THz)

Area for the specified trace.
153
FETC:LENE?
{trace}
Retrieves the end length for the specified trace.
154
