This unit
The Advantest Q8344A is a benchtop optical spectrum analyzer spanning 350 nm to 1750 nm, engineered around Fourier spectrum analysis using a Michelson interferometer. This architecture enables direct optical coherence length measurements - a capability absent in monochromator-based instruments. The analyzer delivers wavelength resolution to 0.05 nm at 0.85 µm, wavelength accuracy of ±0.1 nm, and measurement speeds of approximately 1.5 seconds per sweep across any analysis span.
Dynamic range reaches 80 dB with input sensitivity from −70 dBm to +10 dBm across the 0.7 µm to 1.6 µm band. A built-in He-Ne laser reference ensures long-term measurement repeatability without external calibration.

Frequently Asked Questions
- What does the Advantest Q8344A measure and what is its wavelength range?
- The Q8344A is a benchtop optical spectrum analyzer designed to measure optical power across a broad wavelength span from 350 nm to 1750 nm, covering UV through near-infrared regions. It delivers a maximum resolution of 0.05 nm at 0.85 µm and power measurement sensitivity ranging from −70 dBm to +10 dBm across the 0.7 µm to 1.6 µm band, making it suitable for telecom, fiber-optic component characterization, and broadband light source analysis. The instrument's wavelength accuracy of ±0.1 nm at 1.3 µm enables precise identification of spectral features and compliance verification in communications applications.
- What is the condition of this used Q8344A, and what verification was performed?
- This is a used unit offered as-is, meaning it has seen operational history but remains available for immediate deployment or laboratory service. We verify basic functionality and mechanical condition before listing; however, we recommend independent validation of performance parameters critical to your application, particularly sensitivity and wavelength calibration accuracy. Calibration services are available separately to restore the instrument to manufacturer specifications if needed.
- What does calibration cover for the Advantest Q8344A and what does it cost?
- Calibration for the Q8344A restores wavelength accuracy and power measurement traceability to NIST standards across the instrument's specified operating range. Our calibration service is available separately starting at $450 and typically includes full wavelength and power reference verification; contact us for current turnaround times and the complete scope of your specific calibration needs. This service is strongly recommended if the instrument's last calibration date is unknown or has exceeded your required interval.
- What interfaces and connectivity options does the Q8344A provide?
- The Q8344A supports GPIB (IEEE 488) control for remote operation and data acquisition in automated test systems, enabling seamless integration into rack-and-stack laboratory setups. Driver and command-set documentation are typically available through Advantest; we recommend verifying driver compatibility with your operating system and control software prior to purchase. Standard RS-232 serial connectivity is also present for configuration and basic instrument communication in legacy system integrations.
