5、安诺尼实时频谱分析仪二次研发的频谱数据(Spectrum Data)示例

Spectrum data packets will look like this:
{
"startTime" : 1501163970.1396854,
"endTime" : 1501163970.140799,
"unit" : "dbm"
"payload" : "spectra",
"startFrequency" : 2400250000, "endFrequency" : 2487750000,
"minPower" : -95,
"maxPower" : 5,
"antenna" : {
"name" : "Block_IsoLOG_0"
"latitude" : 50.13646697998047,
"longitude" : 6.320250034332275,
"azimuth" : -2.748893976211548,
"declination" : 0,
},
"sampleDepth" : 1,
"sampleSize" : 448,
"samples" : [
[ -90.05, -90.05, ... , -81.01 ],
...
[ -81.65, -78.05, ... , -90.01 ]
],
}
 
IQ Data
IQ Samples are transmitted as a flat array of alternating I and Q values.
{
"payload" : "iq",
"unit" : "generic"
"minPower" : -2,
"maxPower" : 2,
"sampleDepth" : 1,
"sampleSize" : 2,
"samples": [
5.12e-05, 0.00132,
0.000885, 0.00124,
0.000566, 0.000654,
-0.000615, 2.35e-05,
0.00042, -0.000276,
-0.000723, -0.000343,
-0.000672, 0.000195,
0.000843, -0.000228,
...
]
}
Data that is captured from a source that is not calibrated will have a unit type of generic. The used value
range will be given by the min and max power values.
 
Histogram Data
Histogram data transfers percentages of bin usage. The sample size is like the spectrum or category
data, but the sample depth is used to separate the bins. The sample data is a 2D array with the
dimensions sample size and sample depth packed into a flat 1D JS array.
{
"startTime" : 1506933004.0587604,
"endTime" : 1506933004.0911448,
"payload" : "histogram",
"unit" : "percentage"
"startFrequency" : 2402250128,
"endFrequency" : 2489750128,
"maxPower" : 5,
"minPower" : -165,
"sampleDepth" : 256,
"sampleSize" : 896,
"samples": [
[ 0.074, 0.0787, ... 0.0893 ]
],
}
 
Channel power or other category data
The samples in a category ordered packet will have one measurement per category. The categories are
named and may cover an optional frequency range.
name
Name of the category item
startFrequency
Start of a frequency range
endFrequency
End of a frequency range
{
"categories" : [
{
"name" : "Wifi Channel 1",
"startFrequency" : 2401000000
"endFrequency" : 2423000000,
},
...
],
}
 
Antenna Data
Data that was captured using an antenna with e.g. location or directional information will have an
antenna specification field in the packet.
name
Name of the antenna
latitude
Latitude of the antenna
longitude
Longitude of the antenna
azimuth
Azimuth of a directional antenna
declination
Declination of a directional antenna
