SparkFun Environmental Sensor Breakout
BME680 (Qwiic)
-
The SparkFun BME680 Environmental Sensor is a breakout that combines a gas sensor with temperature, humidity and barometric pressure sensing for a complete environmental sensor in a single package. The gas sensor on the BME680 can detect a wide variety of volatile organic compounds (or VOC for short) to monitor indoor air quality. Combine that with precise temperature, humidity, and barometric pressure and the BME680 can work as a completely standalone environmental sensor all in a 1in. x 1in. breakout!

Noise Location Package
Type HFDF
-
National RF’s Type HFDF high frequency location system is a proven noise hunting and location directional antenna system that allows you, in many cases, to walk right up to the source of High Frequency (HF) noise! Used by several power companies around the United States, professional noise hunters, and other communications specialists, the HFDF has located noise sources that emanated from pole power transformers, arcing electric fences, CATV in-line amplifiers, plasma TV screens, and even Marijuana grower’s heating lamps! The system incorporates several plug-in, tunable magnetic loop sensors of a proprietary National RF design, that cover the frequency range between 1.8 MHz and 55 MHz. The unit is packaged in a hand-held, lightweight metallic enclosure, with a pistol grip and a magnetic compass mounted on top. The compass is used to get magnetic bearings to the noise source, which may be plotted on a map to triangulate, and ultimately pin-point, the location of the noise source. In certain cases, our customers tell us that they have been able to walk right up to the interfering noise source and correct the situation on the spot!

Noise Figure Measurements With Vector Correction
S95029B
-
The S95029B noise figure application enables high-accuracy noise figure and noise-power measurements of amplifiers, frequency converters, and mixers by using the Keysight vector-source-correction technique. Using a source-impedance tuner to remove the effects of imperfect system-source match, this technique produces higher accuracy results than Y-factor method and other cold-source implementations--especially for in-fixture, on-wafer, and automated-test environments.
