Printing, Plotting, and Saving Measurement Results
Saving Measurement Results
(CITIfile format), without any direct frequency information. S11 appears first, S21 second,
S12 third, and S22 last. If Channel 2 is active, the same type of file is produced but the file
extension is .d2. If dual display is on, both d1 and .d2 files are produced.
DataXX.d1, created only when
or an ASCII file in CITIfile format. Turning the
suppresses the generation of all the previous file types. The contents of this file are
identical to those of the FileXX.d1 file. The same type of file is produced if Channel 2 is
active, but the file extension is .d2. If dual display is on, both .d1 and .d2 files are produced.
NOTE The DataXX files are much smaller than an entire instrument state, and are
the best way to get just the data you want without saving the entire
instrument state. Selecting more than one disk-save option does not confuse
the analyzer, and simply produces all files associated with the selected
options. The only exception to this is that selecting
suppresses all other selected options.
Files with .s1 and .s2 File Extensions
There are two type of files with .s1 and .s2 file extensions. There is FileXX.s1 (or .s2) and
DataXX.s1 (or .s2).
FileXX.s1 is an ASCII file in Touchstone S2P format. Basically, this is a file in
real/imaginary spreadsheet type format with five columns: frequency in the first column,
S11 in the second column, S21 in the third, S12 in the fourth, and S22 in the fifth column.
If Channel 2 is active, the same type of file is produced but the file extension is .s2. If dual
display is on, both .s1 and .s2 are produced. These Touchstone S2P files are only produced
when a full 2-port calibration is active and
port extensions and electrical delay, if they are turned on, are included in the data.
DataXX.s1 is also an ASCII file in Touchstone S2P format. As with FileXX.s1, DataXX.s1
is a five-column real/imaginary spreadsheet type format where the columns are used the
same as FileXX.s1. If Channel 2 is active, the same type of file is produced but the file
extension is .s2. If dual display is on, both .s1 and .s2 are produced. These Touchstone S2P
files are only produced when a full 2-port calibration is active and
selected. The effects of port extensions and electrical delay, if they are turned on, are
included in the data.
Files with .f1 and .f2 File Extensions
FileXX.f1, produced only when
or ASCII. This file contains the formatted data in whichever format is currently displayed
on the network analyzer (dB, phase, VSWR, and so forth) with error correction, trace
math, port extensions, electrical delay, time domain gating and smoothing applied. Port
extensions are really only evident if the measured parameter is phase. The same type of
file is produced for Channel 2, but the file extension is .f2. If dual display is on, both .f1 and
.f2 are produced. In ASCII format, the data appears as two columns (CITIfile format). If
the currently selected display format is not complex data (neither Smith Chart nor Polar),
the second column will be meaningless (place holder) values.
