User Guide
SYST:RLDC Reloads the most recent valid calibration file into memory. 128
SYST:SAT? Queries whether the detectors were saturated during the
previous scan.
129
SYST:SAVE
{“filename.obr”,
trace}
Saves the specified trace (A-E) data as a binary file using the
specified filename. The file name must be in quotes, and the
file type ".obr" must be specified. If no trace is specified, the
data in Trace A will be saved.
130
SYST:SAVT
{“filename.txt”,
trace, domain,
graphType, units,
spatialResolution}
Saves the current data from the trace specified (A-E) as text
or spreadsheet data in the path specified in quotes, based on
the following variables:
Trace can be A, B, C, D or E.
Domain = 0 for the time domain, 1 for frequency domain.
GraphType can take values from 0 to 8, depending on the
domain specified, as shown in the table on page 145.
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).
SpatialResolution sets the spatial Resolution Bandwidth
(mm).
130
SYST:SPOT
{center, centerUnits
Tells the OBR to execute an optical Spot Scan centered about
the specified center.
CenterUnits:
0 = time (ns)
1 = length (m)
2 = length (ft)
3 = length (in)
4 = length (mm)
