This unit
The Keysight 70952B is a grating-based optical spectrum analyzer module engineered for the 70000 series modular measurement system. It delivers characterization of optical components, amplifiers, LEDs, DFB lasers, and Fabry-Perot lasers across multiple wavelength windows. The module achieves –95 dBm sensitivity with dynamic range to +10 dBm and sweeps 40 nm in 50 ms, enabling rapid measurement cycles in high-sensitivity applications.
Polarization insensitivity and configurable continuous-sweep operation reduce measurement time and mechanical wear.

Frequently Asked Questions
- What does the Agilent/Keysight 70952B measure and what are its key applications?
- The 70952B is an optical spectrum analyzer module that performs frequency domain measurements of optical signals, enabling detailed spectral content analysis, signal power measurement, and identification of signal characteristics across optical wavelengths. I've found this instrument essential for fiber-optic communications testing, wavelength verification, and identifying spectral anomalies in optical transmission systems. It integrates as a module within compatible test platforms, delivering precision optical signal analysis for laboratory and field environments.
- What is the condition of this used 70952B, and what was verified before listing?
- This unit arrives in used condition and has been inspected to confirm operational functionality and mechanical integrity prior to listing. We verify that the module powers correctly at 115 VAC, 60 Hz and that core measurement functions respond to test inputs without error. A full calibration is available separately if you require traceable performance verification to factory standards.
- What calibration services are available for the 70952B, and what does it cost?
- Calibration for the 70952B is available as an optional service starting at $450, and I can arrange this through our qualified service partners to restore traceable accuracy to manufacturer specifications. The calibration typically covers the optical measurement path, wavelength accuracy, and power measurement linearity across the instrument's operational range. Contact our sales team for current turnaround times and to add calibration to your order.
- What interfaces and connectivity options does the 70952B support?
- The 70952B functions as a plug-in module, so its connectivity depends on the host mainframe—typically supporting GPIB (IEEE 488.2) or LAN interfaces for remote operation and data acquisition. I recommend confirming your specific mainframe model to verify driver availability and software compatibility with Keysight's measurement applications and third-party control platforms. Documentation on supported interfaces and required software drivers is available upon request.
