Dielectric Material Test Fixture
16453A
-
The 16453A is designed for accurate dielectric constant and loss tangent measurements on the E4991A/4291A/B. It employs the parallel plate method, which sandwiches the material between two electrodes to form a capacitor. The E4991A/4291A/B measures the capacitance created from the fixure, and option 002 firmware calculates the relative complex permittivity as described in the 16451B. Adjustment to insure parallel electrodes is required when using the 16451B. This adjustment is not required with the 16453A because the fixure has a flexible electrode that adjusts automatically to the material surface.

The most known methods for quality evaluation of voice transmission systems were developed by Telecommunication Standardization Sector of International Telecommunications Union (ITU-T) in the middle of 90-s. Results of this work are presented in Recommendation P.800 (P.830) «Methods for subjective determination of transmission quality» [1, 2]. This document describes conditions for voice quality testing, audio contents, scoring and methods to evaluate results. Typically “Methods for subjective determination of transmission quality” are used to obtain mean subjective quality score according to five-digit scale (Mean Opinion Score – MOS).

Qualification and Quality Control Tests
Techsquare
-
New IEC standards, IEC 60034-18-41 and IEC 60034-18-42, have been issued to define the procedures for testing partial discharge inception voltage and the long-term performance (endurance) of Type I and Type II insulation systems used in rotating machines fed from voltage converters. Voltage impulse generators are required at least to test turn insulation, but they would be recommended for any testing under power electronics supply because of their capability to simulate the real electrical stress conditions. More generally, any type of electrical insulation system when subject to impulsive voltage waveform during life should be carefully evaluated in terms of partial discharge and endurance behaviour. This is why voltage impulse generators able to provide impulses with controlled amplitude and frequency are needed to face this new testing challenge.

BM-windream provides a basis for your data and document management that can be validated at relatively low cost (configurable standard software complying with GAMP5) and is easy to use. Users access your documents using a virtual network drive in Windows Explorer, which means that little training is required. BM-windream provides a standardised user interface over the entire life cycle of a file, from creation to deletion. At all phases in this life cycle, a change history (audit trail) is recorded. BM-windream is suitable for handling all kinds of non-managed documents. BM-Flow integrates directly with BM-windream and provides the document management functions required for SOP management,manufacturing instructions etc. All general employees can then still access the documents using the familiar Windows Explorer, while those responsible for creating documents can also use the workflow interface in BM-Flow.
