Highlights
  • Calculate output voltage and power
  • Specify input voltage (Vpp or Vrms)
  • Calculate attenuation in dB
  • NMR pulse calculations
  • Measure local magnetic field
  • Display barometric pressure

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 50Ω for most systems. There is a new emphasis on NMR utility, with options for calculating pulses based on reference power and pulse length. Powers are in Watts, dBm, and dB values. Measure local magnetic field to check stray static fields from magnets. See the local barometric pressure, useful if the magnet boil-off is high

Verdict

The call

The clearest difference is device support: Coil Calculator at 3 against Attenuator's 1. Coil Calculator also leads on iOS requirement (15.6 vs 17.6). On price, ads and in-app purchases there is nothing between them.
