Frequency Response Analyser
DP-cPCI-7554
-
DP-cPCI-7554 is a cPCI module capable of analyzing the phase and gain characteristics of a system. The system under test is stimulated by the user defined waveform. The obtained response is correlated with the applied stimulus by the on-board DSP processor to determine the phase difference and the gain.Gain and the face analysis is carried out only at sine waveform.

Frequency Converter Unit
FCU
-
The Astronics Frequency Converter Unit (FCU) provides frequency conversion of variable frequency aircraft power. Recent trends in aircraft power systems use variable frequency (VF) generators instead of fixed frequency of 400Hz. While the majority of aircraft loads can use VF power, select loads still exclusively require 400Hz and are best addressed by the use of FCUs. The FCU performs the task of converting the power line frequency by leveraging recent advances in solid-state technology to provide dramatic improvements in performance over traditional frequency converter solutions.

High Frequency Transformers
-
Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.
