Frequently Asked Questions
- What does the Advantest TQ8345 measure and what is its wavelength range?
- The Advantest TQ8345 is an optical spectrum analyzer designed to measure and characterize optical signals across the ultraviolet to near-infrared spectrum. It covers a wavelength range from 0.35 µm to 1.75 µm, making it suitable for telecommunications, component testing, and laser characterization applications. The instrument delivers resolution down to 0.001 nm, allowing you to differentiate closely spaced spectral features with high precision and accuracy of 5 ppm or ±0.1 nm.
- What is the condition of this used Advantest TQ8345, and what was verified?
- This is a used Advantest TQ8345 offered in working condition. We verify basic functionality and optical performance before listing to ensure the unit operates as specified. Calibration status and detailed service history are available upon request, and we offer calibration services separately to bring the instrument to traceable standards if needed.
- What does calibration cover for the TQ8345, and what is the cost?
- Calibration for the TQ8345 covers wavelength accuracy, resolution verification, and absolute power reference alignment across the specified operating range. We provide calibration services starting at $450, which establishes traceability to NIST standards and ensures measurement accuracy meets the 5 ppm specification. Turnaround time and detailed scope are confirmed during the calibration request process.
- What interfaces and software compatibility does the TQ8345 support?
- The TQ8345 features GPIB (IEEE-488) connectivity as its primary interface for remote control and automated measurement routines. The instrument is compatible with standard optical spectrum analyzer control software and legacy test automation environments. Specific driver requirements and software version compatibility should be confirmed with our technical team, as they depend on your host system and application requirements.
