Digitized waveforms may be transmitted to an external device for printing, 
plotting, storage, or waveform analysis. Every instrument is equipped with 
an auxiliary connection for an analog 
X-Y 
plotter. Most applications, however, 
require either a GPlB (Option 10) or RS-232-C (Option 12) interface.

The RS-232-C or GPlB interface is usually ordered as factory installed; 
however, you can order either interface separately for installation on existing 
instruments. (Only one interface can be installed in the instrument at a time.) 
The two interface options are depicted in Figure 3-45 and Figure 3-46.
