Warnings and Notices WARNING To avoid the possibility of injury or death, you must observe the following precautions before switching on the instrument. Insert the power cable plug only into a socket outlet provided with a protective earth contact. Do not negate this protective action by the using an extension cord without a protective conductor. WARNING Never look directly into the end of a fiber or a connector, unless you are absolutely certain that there is no signal in the fiber.

• SCPI commands are written in mixed case: text that you MUST print is written in capitals; text which is helpful but nor necessary is written in lower case. So, the command INITiate[:IMMediate] can be entered either as init[:imm], or as initiate[:immediate]. It does not matter whether you enter text using capitals or lower-case letters. • SCPI commands often contain extra arguments in square brackets. These arguments may be helpful, but they need not be entered. So, the command INITiate[:

Introduction to Programming GPIB Interface GPIB Interface The interface used by your instrument is the GPIB (General Purpose Interface Bus). GPIB is the interface used for communication between a controller and an external device, such as the tunable laser source. The GPIB conforms to IEEE standard 488-1978, ANSI standard MC 1.1 and IEC recommendation 625-1. If you are not familiar with the GPIB, then refer to the following books: • The International Institute of Electrical and Electronics

Introduction to Programming Message Queues How the Input Queue Works The input queue is a FIFO queue (first-in first-out). Incoming bytes are stored in the input queue as follows: 1 Receiving a byte: • Clears the output queue. • Clears Bit 7 (MSB). 2 No modification is made inside strings or binary blocks. Outside strings and binary blocks, the following modifications are made: • Lower-case characters are converted to upper-case. • The characters 00 to 09 and 0B to 1F are converted to spaces
