Detailed Description

An oscilloscope connected over a SDK-to-SCPI bridge that follows our pattern (i.e. uses scpi-server-tools)

Member Function Documentation

◆ DisableChannel()

void RemoteBridgeOscilloscope::DisableChannel ( size_t i )

overridevirtual

Turn a channel off, given the index.

This function may optionally configure channel interleaving, if supported in hardware.

Parameters

i	Zero-based index of channel

Implements Oscilloscope.

Reimplemented in PicoOscilloscope, and UHDBridgeSDR.

◆ EnableChannel()

void RemoteBridgeOscilloscope::EnableChannel ( size_t i )

overridevirtual

Turn a channel on, given the index.

Parameters

i	Zero-based index of channel

Implements Oscilloscope.

Reimplemented in PicoOscilloscope, and UHDBridgeSDR.

◆ ForceTrigger()

void RemoteBridgeOscilloscope::ForceTrigger ( )

overridevirtual

Forces a single acquisition as soon as possible.

Note that PollTrigger() may not return 'triggered' immediately, due to command processing latency.

Implements Oscilloscope.

Reimplemented in DSLabsOscilloscope, and ThunderScopeOscilloscope.

◆ GetChannelCoupling()

OscilloscopeChannel::CouplingType RemoteBridgeOscilloscope::GetChannelCoupling ( size_t i )

overridevirtual

Gets the coupling used for an input channel.

Parameters

i	Zero-based index of channel

Implements Oscilloscope.

Reimplemented in UHDBridgeSDR.

◆ GetChannelOffset()

float RemoteBridgeOscilloscope::GetChannelOffset	(	size_t	i,
		size_t	stream
	)

overridevirtual

Gets the offset, in volts, for a given channel.

Parameters

i	Zero-based index of channel
stream	Zero-based index of stream within channel (0 if only one stream, as is normally the case)

Implements Oscilloscope.

Reimplemented in UHDBridgeSDR.

◆ GetChannelVoltageRange()

float RemoteBridgeOscilloscope::GetChannelVoltageRange	(	size_t	i,
		size_t	stream
	)

overridevirtual

Gets the range of the current channel configuration.

The range is the distance, in volts, between the most negative/smallest and most positive/largest voltage which the ADC can represent using the current vertical gain configuration. This can be calculated as the number of vertical divisions times the number of volts per division.

The range does not depend on the offset.

Parameters

i	Zero-based index of channel
stream	Zero-based index of stream within channel (0 if only one stream, as is normally the case)

Implements Oscilloscope.

Reimplemented in UHDBridgeSDR.

◆ GetSampleDepth()

uint64_t RemoteBridgeOscilloscope::GetSampleDepth ( )

overridevirtual

Gets the current sample depth of this scope.

Implements Oscilloscope.

Reimplemented in PicoOscilloscope.

◆ GetSampleRate()

uint64_t RemoteBridgeOscilloscope::GetSampleRate ( )

overridevirtual

Gets the current sampling rate (in Hz) of this scope.

Implements Oscilloscope.

Reimplemented in PicoOscilloscope, and UHDBridgeSDR.

◆ GetTriggerOffset()

int64_t RemoteBridgeOscilloscope::GetTriggerOffset ( )

overridevirtual

Gets the trigger offset.

Implements Oscilloscope.

Reimplemented in PicoOscilloscope, and UHDBridgeSDR.

◆ IsChannelEnabled()

bool RemoteBridgeOscilloscope::IsChannelEnabled ( size_t i )

overridevirtual

Checks if a channel is enabled in hardware.

Implements Oscilloscope.

Reimplemented in PicoOscilloscope, and UHDBridgeSDR.

◆ IsTriggerArmed()

bool RemoteBridgeOscilloscope::IsTriggerArmed ( )

overridevirtual

Checks if the trigger is currently armed.

Implements Oscilloscope.

Reimplemented in PicoOscilloscope.

◆ PeekTriggerArmed()

bool RemoteBridgeOscilloscope::PeekTriggerArmed ( )

overridevirtual

Checks if the trigger is armed directly on the instrument, without altering internal state or touching caches.

The default implementation of this function simply calls PollTrigger(). This function should be overridden by the driver class if PollTrigger() changes any internal driver state or accesses cached state (including a clientside "trigger armed" flag).

In particular, the multi-scope synchronization feature requires that this function not return true until the instment has confirmed the arm command has completely executed. Otherwise we risk losing trigger events by arming the primary before the secondary is ready to accept a trigger.

Reimplemented from Oscilloscope.

◆ PullTrigger()

void RemoteBridgeOscilloscope::PullTrigger ( )

overridevirtual

Updates m_trigger with any changes made from the instrument side.

Implements Oscilloscope.

◆ PushTrigger()

void RemoteBridgeOscilloscope::PushTrigger ( )

Pushes changes made to m_trigger to the instrument.

	)

overridevirtual

Sets the coupling used for an input channel.

Parameters

i	Zero-based index of channel

Implements Oscilloscope.

Reimplemented in ThunderScopeOscilloscope, and UHDBridgeSDR.

◆ SetChannelOffset()

void RemoteBridgeOscilloscope::SetChannelOffset	(	size_t	i,

overridevirtual

Sets the offset for a given channel.

Parameters

i	Zero-based index of channel
stream	Zero-based index of stream within channel (0 if only one stream, as is normally the case)
offset	Offset, in volts

Implements Oscilloscope.

Reimplemented in UHDBridgeSDR.

◆ SetChannelVoltageRange()

void RemoteBridgeOscilloscope::SetChannelVoltageRange	(	size_t	i,
		size_t	stream,
		float	range
	)

overridevirtual

Sets the range of the current channel configuration.

The range is the distance, in volts, between the most negative/smallest and most positive/largest voltage which the ADC can represent using the current vertical gain configuration. This can be calculated as the number of vertical divisions times the number of volts per division.

The range does not depend on the offset.

Sets the sample rate of the scope, in Hz.

Implements Oscilloscope.

Reimplemented in PicoOscilloscope, and UHDBridgeSDR.

◆ SetTriggerOffset()

void RemoteBridgeOscilloscope::SetTriggerOffset ( int64_t offset )

overridevirtual

Sets the trigger offset.

Parameters

offset Femtoseconds from the start of the capture to the trigger point. Positive values mean the trigger is within the waveform. Negative values mean there is a delay from the trigger point to the start of the waveform.

Implements Oscilloscope.

Reimplemented in PicoOscilloscope, and UHDBridgeSDR.

◆ Start()

void RemoteBridgeOscilloscope::Start ( )

overridevirtual

Starts the instrument in continuous trigger mode.

Most drivers will implement this as repeated calls to the "single trigger" function to avoid race conditions when the instrument triggers halfway through downloading captured waveforms.

Implements Oscilloscope.

Reimplemented in DSLabsOscilloscope, and ThunderScopeOscilloscope.

◆ StartSingleTrigger()

void RemoteBridgeOscilloscope::StartSingleTrigger ( )

overridevirtual

Arms the trigger for a single acquistion.

Implements Oscilloscope.

Reimplemented in DSLabsOscilloscope, and ThunderScopeOscilloscope.

◆ Stop()

void RemoteBridgeOscilloscope::Stop ( )

overridevirtual

Stops triggering.

Implements Oscilloscope.
