- This unit is offered in used condition with full functional verification completed before listing. We inspect all front-panel controls, display responsiveness, and measurement repeatability to confirm operational readiness. Like all our used test equipment, it is ready for immediate deployment in laboratory or field environments.
- Is calibration available for the AQ6370C, and what does it cover?
- Yes—calibration services are available separately starting at $450, covering wavelength accuracy verification across the instrument's operating range and amplitude response validation at key reference points. Turnaround and scope details are confirmed upon quote; we recommend calibration for traceable measurement integrity in regulated environments or when highest accuracy is required.
- What interfaces and connectivity does the AQ6370C support?
- The AQ6370C features GPIB (IEEE-488) for instrument control and remote measurement automation, enabling seamless integration into automated test systems and lab environments. Compatible drivers and control software are available through Yokogawa; we provide guidance on legacy interface adapters and modern data-logging solutions during the sales process.
