PRINTING AND PLOTTING
Description:
In the digital mode a hard copy of the information on the CRT can be made to a
printer or a plotter. The hard copy can consist of trace(s), the trace settings, trace
identification, cursors, measurement results, and the screen graticule.
The oscilloscope and printer/plotter must be interconnected via a suitable cable
and must be set up to the correct interface parameters. The setup of the print or
plot action is made in the UTILITY >> PRINT & PLOT & CLOCK menu. The setup
of the interface parameters is made in the UTILITY >> REMOTE SETUP or the
UTILITY >> RS232 SETUP menu. This is described under the REMOTE
CONTROL IEEE 488.2 and RS-232 functions. The settings of the printer or plotter
are described in the manual that comes with the printer or plotter.
The front panel key HARDCOPY is used to start a print or plot. During the plot
action, the screen shows the message ‘HARDCOPY BUSY: ..% DONE,’ and
during a print or plot action, all front panel keys except HARDCOPY are inactive.
Pressing the HARDCOPY key again stops the hard copy action. Before
continuing, wait for the message ‘HARDCOPY DONE’.
