Most functions of the SDG II can be controlled by any computer with a standard RS-232 serial port. After connecting the SDG II with computer RS-232 through data transmission cable, it's easy to control the SDG II by sending a RS-232 commands. Valid commands return the string "Ok", but invalid commands or queries return the string "Bad".
I can run a program under Labview to send or query RS-232 commands only by pushing buttons. The front control panel and LabView block diagram are shown here.
