Address Continuous Range: Sets the GPIB address for the Model 4500B

(Numeric) 1 to 30

The instrument address can be set to any value

in the range from 1 to 30. Each instrument on

the bus is assigned a unique address.

Listen Term EOI only, Selects the terminating character for the

(Mult. Choice) LF, CR Listen mode.

Each command string sent to the 4500B

requires a terminating signal or character. The

preferred practice is to use the EOI (End or

Identify) signal from the controller. The bus

controller sends the EOI signal with the last

character of each string. The 4500B will

always respond to the EOI signal, either alone

or in combination with a special character.

Some legacy controllers and equipment

cannot generate or respond to the EOI signal.

In this case, a special character, usually the

ASCII line feed (LF) or carriage return (CR)

is used. The EOI signal may also be used in

combination with special characters.

the EOI signal. In this case, a special character, usually the ASCII line

feed (LF), carriage return (CR) or (CRLF or NL) is used. If necessary,

the user can suppress the EOI signal when a special character(s) is
