Platforms
-
The use of switching systems to route instrumentation and stimulus signals to appropriate test points on a unit under test has a very crucial role to play in most electronics test systems. The sharing of test resources, connection of calibration references, load management, and many other functions are all managed by the switching system, the switching system acts as the interface between the unit under test (UUT) and the test equipment.

-
The Keysight S960907B spectrum analyzer (SA) software application adds high-performance microwave spectrum analysis capabilities to the Keysight ENA-X up to 44 GHz. With fast stepped-FFT sweeps resulting from optimized data processing, the SA application provides quick spurious searches over broad frequency ranges. Conduct simultaneous spectrum measurements using test and reference receivers. For efficient measurements of spurious signals emanating from mixers and frequency converters, combine the multi-channel SA with the internal swept-signal generators. The SA application employs source-power and receiver-response calibration as well as fixture de-embedding, providing in-fixture and on-wafer spectrum measurements with the highest level of accuracy.

Multi Channel Optical Fibre Verification
-
The multi-channel optical fibre test system is used in the development and qualification of single mode optical fibres. The fibres are exposed to environmental influences in a climatic chamber in order to analyse the data on insertion loss and reflection. In addition, the current temperature in the climatic chamber is documented. Insertion loss measurement is performed with the help of an optical power meter, laser sources and optical switches. An Optical Time Domain Reflectometer (OTDR) from Exfo is used for the reflection measurements. The system was designed for the simultaneous characterization of 15 sample fibres and one reference fibre.

Industrial Calibrators
-
A temperature calibrator, often called a thermometer calibrator, is used to correct inaccuracies in installed thermometers and temperature sensors, because temperature measurement is a critical parameter in many industrial processes. Although simulators are sometimes called temperature calibrators or thermometer calibrators and may be used to provide thermometer calibration for the electronics in an installed system, a temperature source with a calibrated reference sensor is still required to provide a complete and meaningful calibration. Fluke Calibration industrial and field temperature calibrators include: Metrology Wells; Field Metrology Wells; field dry-well calibrators; handheld dry block calibrators; Micro-Baths; large target infrared calibrators; field IR calibrators; ice-point dry-well; and thermocouple furnaces.
