Frequently Asked Questions
- What does the Agilent/Keysight 70950B optical spectrum analyzer measure?
- The 70950B is a modular optical spectrum analyzer that measures optical power, wavelength, and spectral characteristics across a defined range. It delivers wavelength accuracy of ±1 nm under standard conditions and ±20% accuracy for measurements at resolutions ≥0.5 nm, making it suitable for fiber optic signal analysis, component characterization, and telecommunications testing. This module integrates into Agilent/Keysight mainframe systems to provide precise optical spectral measurements in laboratory and field environments.
- What condition is this 70950B in, and what was verified before listing?
- We list this 70950B as used equipment that has been functionally verified for basic operation and mechanical integrity. All optical and electrical connectors have been inspected, and the module is confirmed to power on and respond to control commands. For complete confidence in measurement accuracy and performance against published specifications, we recommend independent calibration before deployment in critical applications.
- Is calibration available for the 70950B, and what does it cover?
- Yes, we offer calibration services for the 70950B starting at $450, which verifies wavelength accuracy, optical power measurement linearity, and detector response across the instrument's operating range. Calibration documentation typically includes before-and-after measurements traceable to NIST standards and a calibration certificate with validity period. Turnaround time and specific scope can be confirmed during the calibration inquiry process.
- What interfaces and control options does the 70950B support?
- The 70950B module connects to compatible Agilent/Keysight mainframes via the standard backplane interface and supports remote control through GPIB (IEEE 488) and LAN/Ethernet connectivity on the host system. Compatible software includes Keysight's instrument drivers and measurement applications designed for optical testing; specific driver availability depends on your host platform and firmware revision. We recommend verifying driver and OS compatibility with the host mainframe before integration.
