Page 6: General Information
TLS is over 100nm/s allowing users to access their desired wavelength quickly and efficiently. The TLS offers a user friendly LED display that can be controlled manually with the use of the front panel buttons, but also offers the possibility of remote control through GPIB and RS232. -
Page 7: Output Port
TLS User Manual Output Port The output port of the TLS tunable laser source is equipped with an ultra-low backreflection APC connector. Extreme care must be taken to avoid damaging the connector when plugging and unplugging output jumper. Connection must be kept clean and should be inspected before every mating. -

Page 29: Remote Control Commands
TLS User Manual REMOTE CONTROL COMMANDS Command Syntax and Style Program Message Formats A program message consists of a command header, followed by its required parameters. The parameters must be separated from the command header by a space, for example, *ESE 10. Multiple parameters must be separated by a comma ( , ). -
Page 30: Specifying The Command Path
TLS User Manual Specifying the Command Path In order to use a command in the command tree, the meter must know the full path to the command. If the command is the first command in the program message, the command header must contain the full path to the command. -
Page 31: Implemented Status Structures
TLS User Manual Implemented Status Structures TLS Tunable Laser Source has the following status data structures implemented: IEEE 488.2 defined standard registers (standard status structure) The 488.2 standard status structure consists of four registers: status byte register ... - Page 32 TLS User Manual Bit 6, as the service request bit, is set to 1 if a service request has been generated. Bit 6, as the master summary bit, is set when there is at least one reason for the laser source to request service from the controller. That is, the master summary bit is set if any summary bit in the status byte register is set and if the corresponding bit in the service request enable register is also set.
-
Page 33: Queues
Queues Input Queue The input queue in the TLS Tunable Laser Source is a first-in-first-out (FIFO) queue and is 128 characters in length. Data bytes received from the controller are placed in the input queue in the order received. When a full message is received, it is transferred to the parser. -
Page 34: Output Queue
However, the RS232C interface has no DAQ signal and cannot be signaled when the input queue becomes full. Therefore, characters sent to the TLS Source are lost. If a new program message is received before the response to a query in a previous message is read, the output queue is cleared, MAV is set to false, and the query error bit is set. - Page 35 TLS User Manual -130 Suffix error An error was detected in the suffix sent with the command, but the parser cannot be more specific. -220 Parameter error An error was detected in a parameter, but the control block cannot be more specific.

- Page 41 TLS User Manual Operation Complete Query Syntax *OPC? Function Places a “1” in the output queue of the source when all pending operations have been completed. Because the “1” is not always placed in the output queue immediately, the status byte register should be polled and the MAV bit checked to determine if there is a message available in the output queue.
- Page 42 TLS User Manual Read Status Byte Query Syntax *STB? Function Returns the contents of the status byte register as an integer that, when converted to a binary number, represents the bit values of the register. The bit value for bit 6 of the register is the MSS bit value, not the RQS bit value.
