FS22 SI
:ACQUisition:WAVElength:CHANnel:C?
Returns the peak wavelength of the fiber Bragg grating sen
sors in channel C of the FS22 according to the threshold
settings. The number of channels can be “A” to simultane
ously retrieve the data relative to all sensors in all channels.
Example:
Command
:ACQU:WAVE:CHAN:1?
Answer
:ACK:1523.6573, 1554.0709,
1566.7846
Continuous Acquisition
:ACQUisition:OSATrace:CONTinuous:STARt
Simultaneous continuous acquisition of optical spectrum
traces of all channels. This command is sent via port 3500
and corresponding data is received through port 3365 in
binary format. The answer is a big endian binary stream rep
resenting a double precision (8 bytes) array with 20001
points times the number of optical channels of the interroga
tor. The first 4 bytes of the binary stream indicate the number
of data bytes to be read. To be in agreement with the com
munication protocol syntax of the interrogator, Carriage
Return/Line Feed (CR/LF) are also included in the stream
and, therefore, "2" must be added to the value returned by
the first 4 bytes of the stream.
The returned data represents the power values of the OSA
traces for all optical channels with points from 1500 nm to
1600 nm sampled every 5 pm.
Example:
Command
:ACQU:OSAT:CONT:STAR

Port 3500 » :ACK
