Attenuator 对比 SatRadio 的使用情况和统计数据
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.
Do EPR conversions between g-factor, microwave frequency and magnetic field.
See the local barometric pressure, useful if the magnet boil-off is high

Some tools often needed in radio & satcom engineering :
- dish antenna : axial ratio, gain from X/Y apertures, line of sight mask, radiation pattern, factor of merit G/T, main lobe aperture, off-axis radiation, temperature, wind deflection
- frequency : phase noise, doppler, phase modulation index, wave length
- links : on-axis radiation, coaxial losses, individual radio link, mismatch losses, on-axis transmitter EIRP link, waveguide, optical fibers
- modem : C/N & C/I, PER & BER, phase noise contribution, PSK waveform
- miscellaneous : AM & PM, cooling, dB & %, dB calculator, degrees converter, electrical field, heading & distance, graceful degradation, group delay, IM3-IP3-NPR, power conversion, RF link availability, noise factor
