Tunable Laser Source

Remote Control
The IQ-2600B 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.
Note:
If you have already designed a GPIB program to control a tunable laser
source from EXFO’s FLS Series (FLS-2600B), you can reuse sections for the
IQ-2600B.
SCPI Commands
Command Structure
The GPIB commands follow the guidelines determined by the Standard
Commands for Programmable Instruments (SCPI) consortium. For
example, the command syntax:
FORM(0..26):READ[:DATA]<space><digits>
is used to change the measurement display resolution (number of digits
after the decimal point) for an IQ-2600B Tunable Laser Source.
In this particular example,
➤
FORM identifies that the command is a part of the SCPI FORMat subset
of commands.
➤
(0..26) is the module address modifier and identifies the specific
module to which the command is addressed.
For more information about the address modifier and choosing a
module, please refer to the
IQ-200 Optical Test System
instruction
manual.
Note:
Commands sent to the IQ Optical Test System do not require the address
modifier.
