1229a Frequency Generator
Precise Time and Frequency, Inc.
The ptf 1229A utilizes the latest technological advances in precision frequency synthesizers to provide a multiple output, wide range, high precision frequency reference instrument, capable of delivering frequencies over the range of 0.1Hz up to 30MHz with a resolution of 0.1 Hz over the full range.The unit includes an external reference input to allow extremely high accuracy outputs at precisely the frequency required, together with a front panel indicator to verify “lock” to the external reference. The standard unit includes two independent frequency outputs of any frequency within the range, and provides both sine and square wave outputs for each frequency.An expansion module gives the capability to increase the number of independent frequency outputs up to a total of four frequencies, with sine and square wave outputs for each, giving a total of eight outputs.

SiTek Standard PSD
1L20_CP3
The SiTek Standard PSD (Position Sensing Detector) has high resolution, fast response and outstanding linearity. It is used in a wide variety of applications, most of them utilizing light sources in the visible or near-infrared part of the spectrum. The spectral range covers the region 400 - 1100 nm. Thanks to SiTek's proprietary AR-coating, optimized around 860 nm, a reflection loss of only 2% is achieved around the responsivity peak. Most of the detectors have a cover window to avoid handling damages.

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.

Multi-Element Standards
These multi-element standards consist of multi-layer thin film coatings, one on top of the other, upto a maximum of 6 elemental coatings. It is generally recommended to have coating thicknesses < 20 µg/cm2, so as to cause negligible notable matrix effects, in particular absorption of X-rays emitted in lower deposits by those covering them.
