Attenuator app for iPhone/iPod touch

Attenuator app for iPhone/iPod touch

Tim Burrow (University of Toronto) wrote a utility application for the iPhone/iPod touch that calculates attenuation values:

http://itunes.apple.com/ca/app/attenuator/id367216554

Attenuator is a utility for anyone working with radio frequency sources and needs to know power and voltage after attenuation.

You can specify an input voltage (Vpp or Vrms) and dB of attenuation to get the output voltage, power and attenuation. The impedance can be specified, typically 50 Ohm for most systems.

This free application is available in English, French, Chinese and Japanese and is sponsored by Open Technologies.

[U. of Ottawa NMR Facility Blog] The Bruker Almanac for iPhone / iPod The Bruker Almanac for iPhone / iPod Over the years, I have made much use of the Bruker Almanac. My bookshelf still holds several copies from the past 20 years or so. For those who have never seen a copy, it contains a great deal of useful information for NMR, EPR, ENDOR, IR and mass spectrometry. The NMR information includes, useful NMR formulas, chemical shift tables for some of the commonly observed isotopes, reference compounds, frequency tables etc... Recently Bruker has released its almanac in an iPod / iPhone app. Not only can you use your iPod / iPhone to take a course on Fourier...	nmrlearner	News from NMR blogs	0	08-11-2011 02:24 AM
