YOKOGAWA AQ6360 Optical Spectrum Analyzer

Maintenance and Calibration

1. Firmware update

Update purpose: To enhance the functionality and usability of the instrument, the latest firmware needs to be downloaded from the Yokogawa official website;

Update method:

USB update: Create an "Update" folder in the USB root directory, place the. upd firmware file, and execute it through System → Version → Update (USB);

Network update: Connect to the PC via Ethernet, copy the firmware to the internal Update directory of the instrument, and execute it through Update (NETWORK);

Attention: Do not turn off the power during the update. The instrument will automatically restart after the update, and the settings data will be initialized (backup is required in advance).

2. Accuracy calibration

Wavelength calibration:

Applicable scenario: After 1 hour of preheating and before measurement, ensure wavelength accuracy (±) 0.02nm@1520-1580nm ）；

Tools: Use built-in reference light sources (/LFC/LSC options) or gas lasers with known wavelength accuracy;

Exception handling: If the error is greater than ± 5nm, contact the dealer for adjustment.

Level calibration:

Tools: 1310/1550nm light source, optical power meter;

Process: Connect the light source to the instrument, measure the peak level, and then connect the light source to the optical power meter to confirm that the difference between the two is within ± 0.5dB (meeting the level accuracy requirements).

3. Daily maintenance and component replacement

Daily cleaning:

External: Wipe with a dry cloth after power failure, and prohibit volatile chemicals;

Optical interface: Clean the connector end face with an alcohol swab and disable compressed air blowing (to prevent dust from entering the monochromator).

Component replacement cycle:

Key Explanation of Component Name Replacement Cycle

LCD backlight ≈ 70000 hours lifespan reference value under normal usage conditions

It is recommended to replace the cooling fan regularly for 3 years to prevent overheating

Backup battery (lithium battery) for 5 years to store settings data, needs to be replaced if expired

Safety and Compliance

1. Safety Warning

Warning (risk of fatal/serious injury):

Cannot directly view the optical output interface (built-in reference light source continuously outputs infrared light, which may cause blindness);

Grounding must be used, and ungrounded extension cords are prohibited;

Do not use in flammable and explosive environments, and do not disassemble the instrument by yourself (there is high pressure inside).

CAUTION (Minor Injury/Equipment Damage Risk):

The instrument is a Class A industrial equipment, which may cause radio interference when used in residential areas and needs to be resolved by the user themselves;

To avoid strong light input (which may damage optical components), initialization must be completed before connecting the DUT.

2. Compliance requirements

Environmental compliance: compliant with the EU WEEE Directive (must not be mixed with household waste for disposal) and the Battery Directive (lithium batteries must be separately recycled);

Laser compliance: The built-in laser light source is Class 1 (compliant with IEC 60825-1:2014, 21 CFR 1040.10/11), with a wavelength of 1.53 μ m and a maximum output power of 0.04mW;

Regional compliance: Taiwan region needs to inquire about restricted substance information for power cord (A1100WD) (official website) https://tmi.yokogawa.com/support/... ）.
