Struct Vrt49Context 

pub struct Vrt49Context {
    pub gain_db: f32,
    pub temperature_c: f32,
    pub rf_ref_freq_hz: f64,
    pub timestamp_int_sec: u32,
    pub timestamp_frac_ps: u64,
    pub bandwidth_hz: f32,
    pub sample_rate_sps: f64,
}

Hardware context from a VITA 49.2 (VRT) context packet.

Populated by the integration layer from VRT context extension packets. The DSFB engine reads these fields but never writes VRT packets.

VRT Field Mapping

VRT Field	DSFB Usage
Reference Level	Maps to admissibility envelope scaling
Gain	Distinguishes AGC drift from signal-level drift
Temperature	Correlates thermal drift with PA thermal motif
RF Reference Freq	Detects LO offset / frequency drift
Timestamp (picosec)	Sub-nanosecond event timestamping
Bandwidth	Contextualizes spectral mask width

Fields

gain_db: f32

Receiver gain in dB (from VRT Gain field, CIF 0 word).

temperature_c: f32

Device temperature in °C (from VRT Temperature field). f32::NAN if not available.

rf_ref_freq_hz: f64

RF reference frequency in Hz (from VRT RF Reference Frequency field).

timestamp_int_sec: u32

Integer-seconds timestamp (from VRT Integer-Seconds Timestamp).

timestamp_frac_ps: u64

Fractional-seconds timestamp in picoseconds (from VRT Fractional Timestamp).

bandwidth_hz: f32

Bandwidth in Hz (from VRT Bandwidth field).

sample_rate_sps: f64

Sample rate in samples/sec (from VRT Sample Rate field).

Implementations

impl Vrt49Context

pub const fn unknown() -> Self

Create a context with unknown/default values.

pub fn has_temperature(&self) -> bool

Returns true if a valid temperature reading is available.

pub fn has_rf_freq(&self) -> bool

Returns true if a valid RF reference frequency is set.

Trait Implementations

impl Clone for Vrt49Context

fn clone(&self) -> Vrt49Context

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Vrt49Context

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Vrt49Context

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Vrt49Context

fn eq(&self, other: &Vrt49Context) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
