Frequently Asked Questions

What does the Advantest Q8381 measure and what is its wavelength range?
The Advantest Q8381 is an optical spectrum analyzer designed to measure optical power across a broad wavelength range from 350 nm to 1750 nm, covering UV, visible, and near-infrared spectra. It provides a power measurement range of –85 dBm to +10 dBm, making it suitable for fiber optic characterization, component testing, and wavelength-dependent analysis in telecommunications and research applications. This wide spectral coverage allows the Q8381 to analyze multiple optical signal types in a single instrument.
What condition is this Advantest Q8381 unit in, and what was verified before listing?
This Q8381 is a used unit that has been inspected and tested prior to listing. We verify operational functionality across its stated power and wavelength ranges to confirm the instrument meets its documented specifications. A separate calibration certificate is available for $450 and higher if full NIST-traceable certification is required for your application.
Is the Advantest Q8381 calibrated, and what does calibration cover?
The Q8381 is offered as-is unless you select our optional calibration service, which is available separately starting at $450. Calibration covers verification and adjustment of wavelength accuracy and power measurement linearity across the instrument's full operating range (350–1750 nm, –85 to +10 dBm), and includes a traceable calibration certificate. Contact us for current turnaround times and any custom calibration requirements specific to your test environment.
What interfaces and connectivity options does the Q8381 support?
The Advantest Q8381 features GPIB (IEEE-488) connectivity for remote control and automated test integration, allowing it to integrate into laboratory automation systems and ATE platforms. Consult the instrument's user manual or contact our team for details on compatible software drivers, any available USB or Ethernet interface modules, and software support for your operating system. We can assist with connectivity questions and provide documentation upon request.
