Frequently Asked Questions
- What does the Advantest Q8383 measure and what is its wavelength range?
- The Advantest Q8383 is an optical spectrum analyzer designed to measure optical power across the 550 nm to 1750 nm wavelength range, covering visible through near-infrared applications. It delivers a power measurement range from −92 dBm to +20 dBm, making it suitable for fiber optic component characterization, DWDM system analysis, and laser wavelength verification. The Q8383's broad spectral coverage and sensitive dynamic range support both research and production-level optical signal analysis.
- What is the condition of this used Advantest Q8383, and what has been verified?
- We list this unit as used, meaning it has prior operational history but is fully functional and ready for deployment. Our pre-sale verification confirms that all core measurement functions operate within specification across the stated wavelength and power ranges. We recommend calibration before critical metrology work; calibration services are available separately starting at $450 to ensure traceable measurement integrity.
- Is calibration available for the Q8383, and what does it cost?
- Yes, we offer calibration services for the Q8383 separately, beginning at $450, which ensures the instrument meets manufacturer specifications for accuracy and measurement confidence. Calibration typically verifies wavelength accuracy, power measurement linearity, and sensor responsivity across the full 550–1750 nm range. Contact us for current turnaround time and any additional options such as NIST traceability documentation.
- What are the connectivity and interface options for the Q8383?
- The Advantest Q8383 is equipped with standard laboratory interfaces for instrument control and data collection, though we recommend consulting the instrument manual or contacting us for detailed interface specifications (GPIB, USB, or Ethernet availability). Driver support and compatible software packages depend on your operating environment and application requirements. We can provide guidance on integration with your existing test systems and data acquisition workflows upon request.
