The selection and initiation of this output is controlled by the Hard
Copy keys.
Tabular Printout An example of a tabular format is shown in Figure 6-12 (page 6-16).
The tabular formats are used as follows:
q Tabular Printout Format: Used when printing three or four chan-
nels.
q Alternate Data Format: Used when printing one or two channels.
In tabular printouts, the 37XXXC shifts the data columns to the left
when an S-Parameter is omitted. Leading zeroes are always sup-
pressed. The heading (Model, Device ID, Date, Operator, Page) ap-
pears on each page.
Screen-Image Printout In a Screen-Image Printout, the exact data displayed on the screen is
dumped to the printer. The dump is in the graphics mode, on a
pixel-by-pixel basis.
Plotter Output The protocol used to control plotters is “HP-GL (Hewlett-Packard
Graphics Language). HP-GL contains a comprehensive set of vector
graphics type commands. These commands are explained in the Inter-
facing and Programming Manual for any current model
Hewlett-Packard plotter, such as the 7470A.
When the plotter is selected as the output device, it is capable of draw-
ing the graph shown on the screen or of drawing only the data trace(s),
so that multiple traces may be drawn on a single sheet of paper (in dif-
ferent colors, if needed).
Disk Output The 37XXXC can write-to or read-from the disk all measured data.
This data is stored as an ASCII file in the exact same format as that
shown for the tabular printout in Figure 6-12. If read back from the
disk, the data is output to the printer. There, it prints as tabular data.
