• FileXX.p is a binary file which contains portions of the instrument state specific to later instruments.
Files with .10, .11, .12, .1a, .1b, and .1c File Extensions
The following files are only produced if you have an active calibration. FileXX.10 is a binary file which stores
the stimulus state of the instrument as it relates to an active calibration (specifically, the Power, Sweep
Setup, Start, Stop, Center, and Span settings).
The same type of file is produced if Channel 2 is active, but the file extension is .20 instead of the .10 file
extension mentioned in the previous paragraph.
Files FileXX.11 through .12, .1a, .1b, and .1c are binary files which contain the 12 error correction coefficients
for Channel 1. If Channel 2 is active, it will have the same array, but file extensions are in the form .21, .22,
.2a., .2b, and .2c. If you save in ASCII format, only .10 and .1c are produced, with .1c containing the entire
error correction array in a two-column, real/imaginary (CITIfile) format.
Files with File Extensions .r1 through .r8
FileXX.r1 through .r4 are produced when is turned ON. They may be either binary
or ASCII, and contain the four raw uncorrected S-parameters for channel 1. Channel 2 has the same array,
but file extensions are .r5 through .r8. In ASCII format, the data is displayed as two columns of
real/imaginary numbers (CITIfile format); S11 appears first, S21 appears second, S12 appears third, and S22
appears last.
Files with .d1 and .d2 File Extensions
There are two type of files with .d1 and .d2 file extensions. There is FileXX.d1 (or .d2) and DataXX.d1 (or .d2).
FileXX.d1, produced only when is turned ON, may be either binary or ASCII. This
file contains the error-corrected measurement data, but without port extensions or electrical delay. In ASCII
format, this is a two-column real/imaginary array (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 is turned ON, is either a binary file or an ASCII file
in CITIfile format. Turning the softkey ON 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).
