}

Settings structure for the application. All fields in this structure are available through MQTT and can be configured at runtime.

Fields

ch: [ChannelSettings; 2]

Channel-specific settings.

ext_clk: bool

External reference

Value

true for external 100 MHz reference input selected, false for internal 100 MHz XO enabled and selected

Default

false

lockin_freq: u32

Lockin local oscillator frequency tuning word. Common to both demodulation/input channels.

The demodulation DDS frequency tuning word is /ch/+/input/freq + lockin_freq*0x8000 (lower sideband).

TODO: settle pll and lockin settings into design after confirming optimal choice

Default

0x40 corresponding to 244 kHz. 5/8 Nyquist.

pll_k: i32

Lockin demodulation oscillator PLL bandwidth. This PLL reconstructs the DDS SYNC clock output on the CPU clock timescale.

TODO: settle pll and lockin settings into design after confirming optimal choice

Default

/pll_k = 0x4_0000 corresponds to to a time constant of about 0.4 s.

telemetry_period: u16

Telemetry output period in seconds

Default

2 second interval

stream: Target

Target for data streaming

Default

Streaming disabled
