:ACQUisition:OSATrace:CHANnel:C?
Acquires the optical spectrum trace of the fiber Bragg grating sensors in the C chan­
nel of the FS22. Returns the optical spectrum trace over the complete wavelength
range. The number of channels can be set A to retrieve the optical spectrum trace of
all channels simultaneously. The optical spectrum trace of each channel consists of
20001 points indicating the power of the wavelenghts in the [1500; 1600] nm range;
equally spaced by 5 pm.

:ACQUisition:POWEr:CHANnel:C?
Acquires the power of the fiber Bragg grating sensors in the C channel of the FS22.
Returns the power value of the fiber Bragg grating sensors accordingly to the thresh­
old settings and measurement method. The number of channels can be set to A to
retrieve the data relative to all sensors in all channels simultaneously.
Example:
Command :ACQU:POWE:CHAN:1?
Answer :ACK:-41.064,-40.965
:ACQUisition:WAVElength:CHANnel:C?
Returns the peak wavelength of the fiber Bragg grating sensors in channel C of the
FS22 according to the threshold settings. The number of channels can be “A” to simul­
taneously retrieve the data relative to all sensors in all channels.
Example:
Command :ACQU:WAVE:CHAN:1?
Answer :ACK:1523.6573, 1554.0709, 1566.7846
