Plotting Multiple Measurements Per Page From Disk
The following procedures show you how to store plot files on a LIF formatted disk. A naming
convention is used so you can later run an HP BASIC program on an external controller that
will output the
flies
to the following peripherals:
n a plotter with auto-feed capability, such as the HP
7550B
n an
HP-GL/2
compatible printer, such as the LaserJet 4 series (monochrome) or the DeskJet
1200C
or DeskJet
1600C
(color)
The program is contained on the “Example Programs Disk” that is provided with the
HP 8753E Network
Analyzer
Programmer’s
Guide. The
file
naming convention allows the
program to initiate the following:
n
to initialize the printer for HP-GL/2 at the beginning of a page
n to plot multiple plot
flies
on the same page
n to send a page eject (form feed) to the hardcopy device, when all plots to the same page have
been completed
The plot
file
name is made up of four parts; the first three are generated automatically by the
analyzer whenever a plot is requested. The two digit sequence number is incremented by one
each time a
tie
with a default name is added to the directory.

Plot Multiple Measurements on a Full Page
You may want to plot various files to the same page, for example, to show measurement data
traces for different input settings, or parameters, on the same graticule.
