1. Press Utility > GPIB/RS-232 > RS-232 Baud Rate > 9600
Use baud rates 57600 or lower only. Select the signal generator’s baud rate to match the
baud rate of your computer or UNIX workstation or adjust the baud rate settings on your
computer to match the baud rate setting of the signal generator.
NOTE The default baud rate for VISA is 9600. This baud rate can be changed with
the “VI_ATTR_ASRL_BAUD” VISA attribute.

the signal generator and prints them to the display.
4. Connect an RS-232 cable from the computer’s serial connector to the signal generator’s
AXILLARY INTERFACE connector. Refer to Table 1-13 for RS-232 cable information.
NOTE Any 9 pin (male) to 9 pin (female) straight-through cable that directly wires
pins 2,3, and 5 may be used.
