Hardware¶

Overview¶

The hardware essentially can be divided into three groups: antennas, amplifiers and the controller. Here's a simplified flow chart with three antennas:

graph LR

subgraph Amplifier Board
    PAMP1
    PAMP2
end

subgraph Amplifier Board
    PAMP3
end

ANT1([H Field Antenna 1]) --> PAMP1[H Field pre Amp. 1]
ANT2([H Field Antenna 2]) --> PAMP2[H Field pre Amp. 2]
ANT3([E Field Antenna]) --> PAMP3[E Field pre Amp.]
PAMP1 ---> AMP1[Amplifier 1]
PAMP2 ---> AMP2[Amplifier 2]
PAMP3 ---> AMP3[Amplifier 3]
GPSANT([GPS Antenna]) --> G
N <--->|Ethernet| I[(Internet)]

subgraph CTRL ["Controller Board"]

    AMP1 --> ADC1
    AMP2 --> ADC2
    AMP3 --> ADC3
    G[GPS] <-->|Data| CPU
    G[GPS] -->|1PPS| CPU
    CPU <--> N[Network Controller]

    subgraph AMPS ["Amplifier"]
        direction TB
        AMP1
        AMP2
        AMP3
    end

    subgraph MCU ["Microcontroller Unit (MCU)"]
        ADC1 & ADC2 & ADC3 --> CPU{CPU}:::cpu
    end


    %%messes up everything
    %%GAIN -.-> AMP1
    %%GAIN[Gain Control] --> MCU

end
