Attenuator app for iPhone/iPod touch

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

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.
