RS-232 Interface Configuration
If your computer has a 9-pin serial port with a male connector, use the
cable included with the function generator. If you need an additional
cable, order the F1047-80002 cable which is part of the Agilent 34398A
Cable Kit. This cable has a 9-pin female connector on each end.
The cable pin diagram is shown below (this is the pinout for the cable
shipped with the 33250A). For proper operation, you must use an
RS-232 cable with the same pinout as shown below.

RS-232 Troubleshooting

Here are a few things to check if you are having problems communicating
over the RS-232 interface. If you need additional help, refer to the
documentation that came with your computer.
• Verify that the function generator's RS-232 interface is selected
(GPIB is the default interface). Then, verify that the function generator
and your computer are configured for the same baud rate, parity,
and number of data bits. Make sure that your computer is set up for
1 start bit and 1 stop bit (these values are fixed on the 33250A).
• Verify that you have connected the correct interface cable and adapters.
Even if the cable has the proper connectors for your system, the
internal wiring may not be correct. You can use the 34398A Cable Kit
to connect the function generator to most computers.
• Verify that you have connected the interface cable to the correct serial
port on your computer (COM1, COM2, etc.).
