### Physical and Environmental

* **Durability:** Known for reliability and durability in manufacturing floors, engineering benches, and can be installed on ships.
* **Ventilation Requirements:** When installed in a cabinet, convection must not be restricted. Ambient temperature outside the cabinet must be less than the product’s maximum operating temperature by 4° C for every 100 watts dissipated. Forced convection is required if total power dissipated in the cabinet exceeds 800 watts.
* **Power Cord:** Always use the supplied three-prong AC power cord for adequate earth grounding. The instrument has autoranging line voltage input.

### Software and Interfaces

* **Operating System:** Utilizes a specially designed Windows 98 application program. Configuration changes made outside of this application may cause the instrument to become inoperable.

### Compatibility

* **Product Status:** The Agilent/Keysight 86122A Multi-Wavelength Meter is listed as an Obsolete product.
* **Replacement Products:** Keysight 86122B and 86122C Multi-Wavelength Meters are listed as replacement options.
