Sound Level Calibrator
521
-
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.

The S930901B spectrum analysis adds high-performance microwave spectrum analysis to the PNA family up to 13.5 GHz. With fast stepped-FFT sweeps resulting from optimized data processing, the SA application provides quick spurious searches over broad frequency ranges. Simultaneous spectrum measurements can be done using up to five test and reference receivers. This multi-channel SA can be used with the internal swept-signal generators for efficient measurements of spurious signals emanating from mixers and frequency converters. 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.

The short-circuit test system refers to what kind of short-circuit test is carried out by which equipment, and how long is the test time. But I have one thing to tell you, the short circuit test is a kind of destructive test, mainly to test the working condition of the used equipment in a crisis situation, or to test how strong the anti-destructive ability of the used equipment is. Just like a lot of equipment in the military must undergo a short-circuit test, some for 3 minutes or longer, in order to resist breaking calls against the enemy during wartime.

Spectroscopic Reflectometer
SR Series

Angstrom Sun Technologies, Inc.
Spectroscopic reflectometer (SR) tools are relative low cost and easy to use. To ensure accurate measurement on spectra, a long working distance and also adjustable working distance set up are professionally designed and considered. Since reflection spectra measurements require to use known reference to calibrate light intensity, it is hard to image that user could get accurate spectra without optimizing signal during such calibration because reference thickness is different from sample substrate's thickness in most of cases. Adjusting power output to lamp is our another consideration in ensuring a good measurement by reducing non-linearity effect of the detector.
