RF and NMR utility

Fast answers for power, pulses, pressure, and fields.

Calculate attenuation, voltage, and RF power; derive NMR pulse settings; and read supported on-device pressure and magnetic-field sensors.

Available for iPhone and compatible with Apple Vision.

Attenuator

NMR pulse calculations

Calculate pulse lengths, B1 field, and RF power from reference pulse and power values.

Attenuation and power

Work across Vpp, Vrms, watts, dBm, and dB with an adjustable impedance.

Barometric pressure

Read local pressure from a supported device’s barometer and choose the units you need.

Magnetic field

Check the local magnetic field using the device magnetometer, with clear strong-field safety warnings.
