Printing, Plotting, and Saving Measurement Results
Saving Measurement Results
Saving in Graphical (JPEG) Form
Graphical measurement results can be saved in JPEG format and used as an illustration in a text editor or
desktop publishing application.
1
Up to eight traces may be saved in the JPEG file. This is done by storing a
measurement using and turning on for each of the
four channels.
1. Press .
2. Make sure that is displayed.
3. Make sure that is underlined. If it is not underlined, press the softkey so
that GRAPHIC is underlined.
4. Insert a 3.5-inch floppy disk in the network analyzer’s disk drive.
5. Press to save the display as a graphic in the JPEG format.
The graphic file may be retrieved from the floppy disk on personal computer and can be imported into an
application that accepts graphics in the JPEG format.
NOTE When saving measurement results graphically, make sure that no onscreen measurement
data is displayed as white. Since media color is often white, any measurement data printed
using white will not be visible.
You may change the analyzer to the factory default color settings by pressing
to correct this problem.
However, to maintain your current color settings (except white), check the measurement
color settings by pressing
. Press
to check the remaining measurement colors. To modify any of the measurement
colors, select the measurement and then choose another color from the list of colors that is
displayed.
Instrument State Files
When an instrument state is saved to a floppy disk, some or all of the following files may be produced. This
depends upon which arrays are selected under the
softkey menu, and whether
the selected save format is BINARY or ASCII. The “XX” part of the file name (FileXX) refers to the number of
the instrument state. The first instrument state saved to any particular disk will be named “File00”, and each
successive state saved to that disk will be numbered “1” higher than the previous state (for example,
“File01”and “File02”).
Files with .i and .p File Extensions
The following two files (.i file and .p file) are always produced, except when is selected.
These files were separated to allow backward compatibility with older instruments. The binary data
contained in these two files is not meant to be read in an external computer:
• FileXX.i is a binary file, which contains the generic portion of the current instrument state (specifically,
1. The network analyzer firmware is based in part on the work of the Independent JPEG Group.
