Transmitting Waveforms
«•-
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 GPIB (Option 10) or RS-232-C (Option 12) interface.
Communicating via
interface Options
The RS-232-C or GPIB 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 3-42 and Figure 3-43.
The 2221A, 2224, & 2232 Optional GPIB & RS-232-C Interfaces User Manual
(070-8159-01) provides you with information about connecting the GPIB and
RS-232-C communication options to external printers, plotters, or computer
ports.
