When repairing and calibrating the WA-7600 Wavelength Meter, our approach at Wyoming Electronics Inc. is meticulous and thorough, aimed at ensuring each component and function meets or exceeds its specified performance standards. Below, we’ll elaborate on how we address and fix issues related to the key specifications of the WA-7600:

1. Wavelength Range and Uncertainty

Range: 1270 nm to 1680 nm (178 THz to 236 THz) Uncertainty: ± 0.3 pm (3?)

To maintain the precise wavelength range and minimize uncertainty, we first diagnose the instrument’s monochromator and optical path for any alignment issues or physical obstructions that could distort measurements. Calibrating wavelength accuracy involves adjusting the monochromator’s settings and verifying these adjustments with known standards. We use high-precision calibration sources that cover the entire range to ensure accuracy across all specified wavelengths.

2. Minimum Resolvable Separation

Separation: 30 pm

For resolving power issues such as minimum resolvable separation, we calibrate the optical resolution components. This involves fine-tuning the instrument’s diffraction grating and detector alignment, ensuring that the WA-7600 can distinguish between closely spaced wavelength peaks at the minimum specified separation.

3. Optical Power Uncertainty

Uncertainty: ± 0.5 dB (2?) within ± 30 nm of 1310 nm and 1550 nm

Calibrating optical power uncertainty is critical, especially around the key wavelengths used in telecommunications (1310 nm and 1550 nm). We address this by calibrating the instrument’s power meter using traceable optical power standards and checking the linearity of the detector’s response at these specific wavelengths. Any deviations are adjusted through firmware or hardware recalibrations to ensure compliance with the stated uncertainty limits.

4. Linearity in dB

Linearity: ± 0.3

To ensure that the linearity remains within ±0.3 dB, our calibration process includes verifying the logarithmic response of the system over its dynamic range. This involves measuring the response to a known signal across the specified dynamic range and adjusting system parameters to correct any non-linearity detected.

5. Optical Input

Input: Optimized for 9/125 µm fiber

Issues with the optical input typically involve ensuring the cleanliness and integrity of the input port and the correct alignment with the 9/125 µm fiber. We inspect and clean all optical connectors and adapters, and realign or replace any damaged components to ensure optimal coupling and minimal insertion loss.

6. Voltage and Frequency

Range: 90 to 260 VAC, 50/60 Hz

The power supply unit (PSU) is calibrated and tested to handle the specified voltage and frequency range. We check for voltage stability and fluctuations and replace or repair components of the PSU if deviations from specified performance are found.

7. Instrument Interface

Interfaces: GPIB (IEEE-488.2), RS-232, and floppy disk drive

To address issues with the instrument interface, we perform tests on each communication port to ensure proper operation. This includes sending and receiving test data through GPIB and RS-232 interfaces and verifying the read/write functionality of the floppy disk drive. Any faults found are rectified by replacing faulty circuitry or updating firmware as needed.
