OPTICAL WAVELENGTH METER 338 Series
Fast and cost-effective wavelength meter for optical transceiver testing.
The 338 Series Optical Wavelength Meter from Bristol Instruments combines speed and affordability to address the most important requirements of optical transceiver manufacturers. The model 338 has a high measurement rate of 25 Hz that results in reduced testing times and greater production throughput. And, its price, along with a fifi ve-year warranty, provides a lower cost of ownership compared with similar systems.
The 338 Optical Wavelength Meter uses proven Michelson interferometer-based technology with fast Fourier transform analysis to measure the wavelength of CW and modulated signals to an accuracy as high as ± 0.3 pm. Continuous calibration with a built-in wavelength standard ensures the utmost confifi dence in the test results.
Operation of the 338 Optical Wavelength Meter is straightforward. A convenient touch-screen display controls the system and displays the wavelength and power measurements in a variety of formats. The data can also be sent to a PC using a library of SCPI commands via USB, Ethernet, or GPIB.
Key Features:
• Fast measurement rate of 25 Hz.
• Wavelength accuracy as high as ± 0.3 pm.
• Continuous calibration with a built-in wavelength standard.
• Measurement confifi dence level of ≥ 99.7%.
• Traceable to NIST standards.
• Power measured to an accuracy of ± 0.5 dB.
• Wavelength range from 1270 to 1680 nm.
• Operates with CW and modulated signals.
• Convenient touch-screen display reports measurement data in a variety of formats.
• Interfacing via SCPI using USB, Ethernet, or GPIB.
• Rugged design for manufacturing environments.
• Five-year warranty covers all parts and labor.
