Attenuator is a versatile utility designed for professionals working with radio frequency sources. The app provides essential features for calculating power and voltage after attenuation. Users can input voltage values (Vpp or Vrms) and specify attenuation in dB to determine output voltage, power, and attenuation levels. Additionally, the app allows users to specify impedance, typically set at 50Ω for most systems.

The latest update of Attenuator includes enhanced NMR utility features, enabling users to calculate pulses based on reference power and pulse length. The app supports power measurements in Watts, dBm, and dB formats. Moreover, users can measure local magnetic fields to identify stray static fields from magnets and perform EPR conversions between g-factor, microwave frequency, and magnetic field values. Lastly, the app provides information on local barometric pressure, particularly useful for monitoring magnet boil-off conditions.
