Frequently Asked Questions

What does the Agilent/Keysight 71450B measure, and what is its wavelength range?
The 71450B is a benchtop optical spectrum analyzer designed to measure optical power across a wide spectral window. It operates from 600 nm to 1700 nm, covering visible through near-infrared wavelengths, with a dynamic range of −95 dBm to +10 dBm. This makes it ideal for characterizing lasers, LEDs, WDM signals, and optical component performance in research and manufacturing environments.
What is the condition of this used 71450B, and what verification was performed?
This unit is offered as used and has been functionally tested to confirm operation within specification. Our technicians verified optical measurement accuracy, wavelength calibration stability, and all front-panel controls before listing. Detailed condition notes and photos are available upon request to ensure transparency in your purchasing decision.
What calibration services are available for the 71450B, and what is the cost?
We offer NIST-traceable calibration starting at $450, which verifies wavelength accuracy and power measurement linearity across the instrument's full range. Calibration turnaround is typically 2–3 weeks depending on current workload. A calibration certificate documenting traceability and uncertainty is provided upon completion.
What interfaces and connectivity options does the 71450B support?
The 71450B features GPIB (IEEE 488.2) for remote control and data transfer, enabling integration into automated test systems and LabVIEW environments. It supports industry-standard SCPI commands for instrument control. Keysight provides drivers and software compatibility with legacy test systems, and technical documentation is available to support custom integration or programming.
