Struct Scope 

pub struct Scope<'a> { /* private fields */ }

Handle for an oscilloscope net: an instrument (scope) or one of its channels (scope-channel). See the module docs for which actions need a channel net.

Implementations

impl<'a> Scope<'a>

pub fn name(&self) -> &str

Name of the net this handle drives.

pub fn enable(&self) -> Result<()>

Turn this net’s channel on.

pub fn disable(&self) -> Result<()>

Turn this net’s channel off.

pub fn is_enabled(&self) -> Result<bool>

Whether this net’s channel is on, as the instrument reports it.

pub fn run(&self) -> Result<()>

Start continuous acquisition.

pub fn single(&self) -> Result<()>

Arm for a single acquisition.

pub fn stop(&self) -> Result<()>

Stop acquisition.

pub fn force_trigger(&self) -> Result<()>

Force a trigger now.

pub fn autoscale(&self) -> Result<()>

Let the instrument pick scale, timebase and trigger.

pub fn set_scale(&self, volts_per_div: f64) -> Result<()>

Set this channel’s vertical scale (V/div).

pub fn scale(&self) -> Result<f64>

This channel’s vertical scale (V/div).

pub fn set_timebase(&self, seconds_per_div: f64) -> Result<()>

Set the timebase (s/div).

pub fn timebase(&self) -> Result<f64>

The timebase (s/div).

pub fn set_coupling(&self, mode: &str) -> Result<()>

Set this channel’s input coupling ("dc", "ac"; a Rigol also takes "gnd").

pub fn coupling(&self) -> Result<String>

This channel’s input coupling.

pub fn set_probe(&self, ratio: f64) -> Result<()>

Set this channel’s probe attenuation (1 for 1x, 10 for 10x).

pub fn probe(&self) -> Result<f64>

This channel’s probe attenuation.

pub fn set_offset(&self, volts: f64) -> Result<()>

Set this channel’s vertical offset (V).

pub fn offset(&self) -> Result<f64>

This channel’s vertical offset (V).

pub fn set_time_offset(&self, seconds: f64) -> Result<()>

Move the capture window in time relative to the trigger (s).

pub fn time_offset(&self) -> Result<f64>

The capture window’s time offset from the trigger (s).

pub fn trigger_edge(&self, trigger: &EdgeTrigger) -> Result<()>

Configure the edge trigger, applying only the fields that are set.

pub fn trigger(&self) -> Result<TriggerSettings>

The trigger as the instrument has it.

pub fn measure(&self, m: Measurement) -> Result<Option<f64>>

Read one quantity from this channel. None when the capture does not contain it (a period on a DC level).

pub fn measure_all(&self) -> Result<Measurements>

Every quantity this channel’s capture supports, read from one capture so the values agree with each other.

pub fn command(&self, action: &str, params: Value) -> Result<Value>

Run any other scope action by name with raw JSON params, and return its value (null when it has none): capabilities, get_state, set_acquire, set_trigger_holdoff, set_roll, fft, the cursor actions, and so on.

Trait Implementations

impl<'a> Clone for Scope<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
