We released version 2 of our free iPhone app The Agilent Microwave calculator. It consists of a Coupler Directivity Error Calculator (useful if you use a VNA), a Mismatch Error Limit Calculator that shows the potential uncertainty in a transmission measurement caused by source and load mismatch, and a handy Ratio-to-dB Calculator for converting dB to power and voltage ratio. It also has a Noise calculator and Antenna calculator.
Besides, it’s cool… in a geeky kind of way… Check it out!
(Compatible with iPhone, iPod touch and iPad. Requires iOS 3.2 or later.)

Thanks!
Can you please check yor free space loss calculations when distance is entered in meters? I may be missing something or it is 10 dB off from the same distance in feet.
Thanks
Hi Bill,

Is there an app for android?
Sorry, Anil, no plans so far. The only Android app we have is a remote control for our handheld digital multimeters. from http://www.agilent.com/find/hh-Android
Best regards, Colin
Hi Bill,
The developers released a bug fix. Please download the latest from the App Store.
Best regards,
