Spectrum or waveform as a packed float array

POST
/GetFFT_Base64
curl --request POST \
  --url https://api.eianalytic.com/ApiWeb.svc/GetFFT_Base64 \
  --header 'Content-Type: application/json' \
  --data '{ "machinecode": 1, "pointindex": 1, "fileid": 1, "axis": true, "OutputType": 1, "SignalTypeOut": 0, "hz": true, "Token": "example" }'

The replacement for GetFFT. Returns the series packed as a base64 string that decodes to a 32-bit little-endian float array, which is far smaller over the wire than coordinate pairs.

Allowed values: 1 2
SignalTypeOut
required

0 = G, 1 = mm/s², 2 = mm/s, 3 = in/s, 4 = µm, 5 = mils, 6 = GE.

⚠️ Ojo con el nombre: false devuelve la frecuencia en Hz y true la devuelve en CPM. El nombre sugiere lo contrario.
