B Trigger Option Theory Your Tunable Laser Source features Trigger In and Out connectors. When the trigger option is set to On, the Trigger In will wait for signals. The Trigger Out is always active and emits a signal for each one-way pass (Continuous mode) or step (Stepped mode) the system performs during the sweep. The synchronization feature uses a TTL, 5 V signal. It is achieved on the signal’s rising edge. The pulse width of the Trigger In signal must be larger than 1 μs.
Trigger Option Theory Trigger Option in Stepped Mode Trigger Option in Stepped Mode The sweep will begin when you press on Start. The system will position itself at the start wavelength and wait for a synchronization signal. Then, the system will wait for a synchronization signal to go to the next step in the sweep. If the synchronization signal arrives before the sweep is completed, it is kept in memory to be used on the next step.
C Remote Control Your Tunable Laser Source can be remotely controlled by either the GPIB interface (through a GPIB cable connected to the GPIB port), or RS-232 interface (through a serial cable connected to the serial port). The commands used in both protocols are the same and described in the following pages. When the FLS-2600B is being remotely controlled by GPIB, Remote appears in the upper right-hand corner of the display.

Remote Control Standard Status Data Structure Tunable Laser Source 79
Remote Control SCPI Commands An SRQ is forced when a bit in the Status Byte register goes from 0 to 1 and the corresponding SRE Mask bit is set. If an SRQ is forced, the Recoverable Queueing Service (RQS) bit is set to 1 and remains as such until it is read by a serial poll, even if the reason or condition that caused the service request no longer exists. Similarly, if a serial poll reads the RQS, it is reset to 0, whether the condition that caused the service request still exists or not.
Remote Control SCPI Commands To enter commands or queries you must use either the full word for the command, or the three- or four-letter shortcut. Commands are not case-sensitive; however, spelling errors will cancel the command or query. The command or query can be written using only shortcuts, only full words, or a combination of both. Other command syntax elements can also be used: the comma, which is used to separate values in a command or query.
Remote Control General Commands General Commands Your tunable laser source recognizes the main commands identified in IEEE 488.2.
Remote Control General Commands *CLS Description This command sets the contents of the Standard Event Register (ESR), the Status Byte Register (STB), and the Error Queue (ERR) to zero. This command is commonly used to clear the status registers before enabling SRQ. Note that the output queue, Standard Event Status Enable Register (ESE), and Service Request Enable Register (SRE) are not affected.
Remote Control General Commands *ESR? Description This query reads the contents of the Standard Event Status Register (ESR) and clears it. Syntax *ESR? Response An integer between 0 and 255. *IDN?
