Frequently Asked Questions
- What does the Agilent 86145B Portable Optical Spectrum Analyzer measure?
- The 86145B is a high-performance optical spectrum analyzer that measures optical power across a wavelength range of 600 nm to 1700 nm, with a dynamic range from –70 dBm to +20 dBm. This instrument is designed for characterizing optical signals in fiber optic networks, laser systems, and broadband optical sources. The portable form factor makes it ideal for field testing, lab verification, and manufacturing quality control in telecommunications and photonics applications.
- What is the condition of this used 86145B, and what was verified?
- We've listed this unit as used inventory, meaning it has prior operational history but has been tested for basic functionality before listing. All power supply specifications (44–444 Hz input frequency, 90–260 VAC) have been confirmed operational. We recommend verification of measurement accuracy through calibration before critical production or compliance work, which is available separately starting at $450.
- Is calibration available for the 86145B, and what does it cover?
- Yes, calibration is available separately for this 86145B unit, starting at $450. A professional calibration ensures wavelength accuracy and power measurement linearity across the full 600 nm to 1700 nm range and –70 dBm to +20 dBm dynamic range. We can provide a detailed quote and turnaround timeline upon request based on your specific calibration requirements and traceability needs.
- What interfaces and connectivity options does the 86145B support?
- The 86145B supports GPIB (IEEE-488) control and RS-232 interfaces for remote operation and automated test integration. It is compatible with Keysight's measurement software suite and third-party instrument control platforms that support standard GPIB protocols. Confirm specific driver availability and software compatibility with our sales team, as we can facilitate documentation and compatibility verification for your test environment.
