Printing, Plotting, and Saving Measurement Results
Saving Measurement Results
• FileXX.i is a binary file, which contains the generic portion of the current instrument
state (specifically, the System, Local, Preset, Copy, Save, and Sequence settings).
• 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.
