Full Band Noise Figure and Gain Test Extenders
STG-06-S1
Full band noise figure and gain test extenders are offered to extend noise and gain measuring capabilities up to higher millimeterwave frequency ranges. These extenders are designed to interface with noise and gain test systems that have an input IF of 10 MHz to 1.6 GHz, such as the industry standard Keysight 8970A/B, N8975A and Maury MT 2075B. The noise figure and gain test extenders include a high-performance, solid-state noise source (STZ series) and a full waveguide down converter (STC series), which consists of a Faraday isolator (STF series), full band mixer (SFB series), frequency multiplier, and IF amplifier. A frequency source with an output signal in the frequency range of 10 to 20 GHz is required as a local oscillator for the down converter. The noise source is automatically powered on and off by the noise figure meter.

Fourier Transform Optical Spectrum Analyzer, 350 - 1100 nm
OSA201C
Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.

CAT-5 Cable Equalizers
Analog Devices high speed, differential receivers and CAT-5 cable equalizers compensate for the transmission losses of UTP and coaxial cables up to 300 meters in length. Our design techniques for products such as the AD8123 optimize performance for low noise, short-to-medium range applications, while also providing the high gain bandwidth required for long cable equalizations. Various gain stages are summed together to best approximate the inverse frequency response of the cable. Logic circuitry controls the gain functions of the individual stages so that the lowest noise can be achieved at short-to-medium cable lengths.

Sound Level Indicators
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.An important attribute to consider when searching for a suitable sound level meter is its type or class. The type or class of a sound level meter defines the device's accuracy as per American National Standards Institute (ANSI) or International Electrotechnical Commission (IEC) guidelines. Typically, "type" is the grade according to the ANSI S1.4 standard, whereas "class" is the grade according to the IEC 61672 standard. There are two types or classes assigned to sound level meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 sound level meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used. PCE sound level meter products are lightweight, easy-to-use and manufactured in accordance with the highest industrial standards.

Environmental Noise Monitors
Noise is one of the most complained about aspects of the environment, as not only does it have the potential to affect quality of life, it can also be difficult to monitor and therefore control. This type of noise is generally called environmental noise. There are many man-made sources of environmental noise, such as wind turbines, industrial sites, roads and traffic etc. If you are looking for equipment to measure noise in the workplace, look at sound level meters.
