1. AC Power Receptacle
The AC power cord receptacle accepts a three–pronged AC power cord that is supplied with the 
signal generator. For details on line setting requirements and the power cord, see the Getting 
Started Guide.
CAUTION To avoid the loss of data, GPIB settings, or current user instrument states that have not 
been permanently saved to non- volatile memory, the signal generator should always be 
powered down either via the instrument’s front panel power button or the appropriate 
SCPI command.
 Signal generators installed in rack systems and powered down with the 
system rack power switch rather than the instrument’s front panel switch display a 
Error - 310 due to the instrument not being powered down correctly.
