Four-Port Tunable Laser System Source
N7714A
Laser Source
The Keysight N7711A and N7714A tunable lasers are single-port and four-port sources, available with C-band or L-band wavelength coverage. The narrow linewidth and offset grid fine-tuning capability make them ideal sources for realistic loading of the latest transmission systems. All models can reach any wavelength point within their specified wavelength range just like all other Keysight tunable lasers. In this mode, code compatibility with existing test setups based on Keysight's range of full-size and compact tunable lasers is a great asset. In system loading applications, it may be preferable to grid-tune the lasers like system transmitters, simply by changing the channel index. The channel grid is adjustable to standard ITU-T grid spacing like 50 GHz, and to arbitrary grids. Likewise, the zero frequency (base channel) of the chosen grid is adjustable. A 12 GHz fine-tuning range allows de-tuning the frequency.

Sound Level Meters
-
A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site.
