Plotting Using an RS-232 Interface
This section describes how to plot using an RS-232 interface. It is critical that the plotter and
the spectrum analyzer be configured to be compatible with each other. Particular attention
should be paid to:
Character Size
&Bits
Parity
OFF
Baud Rate 1200 (typical)
Handshaking DTR=YES, DUPLEX=FULL
Equipment
n HP 8590 Series spectrum analyzer with Option 043.
n HP 24542G 9-25 pin RS-232 cable
n HP
C2932A
9-9 pin RS-232 cable (for use with LaserJet 4P and 4Plus.)
n Any of the following Plotters:
q HP 7440A ColorPro plotter with an RS-232 interface.
q HP 7475A plotter with an RS-232 interface.
q HP
7550A/B
plotter with an RS-232 interface.
Interconnection and Plotting Instructions
The RS-232 interface allows only one device to be connected to the spectrum analyzer. Refer to
the programmer’s guide for more information on RS-232 protocol.
1. Turn off the spectrum analyzer and plotter.
2. Connect the plotter to the spectrum analyzer using an RS-232 cable.
