Member Function Documentation

◆ AcquireData()

bool MockOscilloscope::AcquireData ( )

overridevirtual

Pull data from the instrument.

Returns: True if waveform was acquired, false if connection lost or other serious error

Implements Instrument.

◆ DisableChannel()

void MockOscilloscope::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.

◆ EnableChannel()

void MockOscilloscope::EnableChannel ( size_t i )

overridevirtual

Turn a channel on, given the index.

Parameters

i	Zero-based index of channel

Implements Oscilloscope.

◆ ForceTrigger()

void MockOscilloscope::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.

◆ GetAvailableCouplings()

vector< OscilloscopeChannel::CouplingType > MockOscilloscope::GetAvailableCouplings ( size_t i )

overridevirtual

Gets the set of legal coupling values for an input channel.

Parameters

i	Zero-based index of channel

Implements Oscilloscope.

◆ GetChannelAttenuation()

double MockOscilloscope::GetChannelAttenuation ( size_t i )

overridevirtual

Gets the probe attenuation for an input channel.

Note that this function returns attenuation, not gain. For example, a 10x probe would return 10 and not 0.1.

Parameters

i	Zero-based index of channel

Implements Oscilloscope.

◆ GetChannelBandwidthLimit()

unsigned int MockOscilloscope::GetChannelBandwidthLimit ( size_t i )

overridevirtual

Gets the bandwidth limit for an input channel.

Parameters

i	Zero-based index of channel

Returns: Bandwidth limit, in MHz. Zero means "no bandwidth limit".

Implements Oscilloscope.

◆ GetChannelCoupling()

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

overridevirtual

Gets the coupling used for an input channel.

Parameters

i	Zero-based index of channel

Implements Oscilloscope.

◆ GetChannelOffset()

float MockOscilloscope::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.

◆ GetChannelVoltageRange()

float MockOscilloscope::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.

◆ GetExternalTrigger()

OscilloscopeChannel * MockOscilloscope::GetExternalTrigger ( )

overridevirtual

Returns the external trigger input channel, if we have one.

Note that some very high end oscilloscopes have multiple external trigger inputs. We do not currently support this.

Implements Oscilloscope.

◆ GetInstrumentTypes()

unsigned int MockOscilloscope::GetInstrumentTypes ( ) const

overridevirtual

Returns a bitfield describing the set of instrument types that this instrument supports.

Not all types may be available on a given channel.

Implements Instrument.

◆ GetInstrumentTypesForChannel()

uint32_t MockOscilloscope::GetInstrumentTypesForChannel ( size_t i ) const

overridevirtual

Returns a bitfield describing the set of instrument types that a given channel supports.

Parameters

i	Channel index

Implements Instrument.

Reimplemented from Oscilloscope.

◆ IsTriggerArmed()

bool MockOscilloscope::IsTriggerArmed ( )

overridevirtual

Checks if the trigger is currently armed.

Implements Oscilloscope.

◆ PollTrigger()

Oscilloscope::TriggerMode MockOscilloscope::PollTrigger ( )

overridevirtual

Checks the curent trigger status.

Implements Oscilloscope.

◆ PullTrigger()

void MockOscilloscope::PullTrigger ( )

overridevirtual

Updates m_trigger with any changes made from the instrument side.

Implements Oscilloscope.

◆ PushTrigger()

void MockOscilloscope::PushTrigger ( )

overridevirtual

Pushes changes made to m_trigger to the instrument.

Implements Oscilloscope.

◆ SetChannelAttenuation()

void MockOscilloscope::SetChannelAttenuation	(	size_t	i,
		double	atten
	)

overridevirtual

Sets the probe attenuation used for an input channel.

Parameters

i	Zero-based index of channel
atten	Attenuation factor

Implements Oscilloscope.

◆ SetChannelBandwidthLimit()

void MockOscilloscope::SetChannelBandwidthLimit	(	size_t	i,
		unsigned int	limit_mhz
	)

overridevirtual

Sets the bandwidth limit for an input channel.

Parameters

i	Zero-based index of channel
limit_mhz	Bandwidth limit, in MHz. Zero means "no bandwidth limit".

Implements Oscilloscope.

◆ SetChannelCoupling()

void MockOscilloscope::SetChannelCoupling	(	size_t	i,
		OscilloscopeChannel::CouplingType	type
	)

overridevirtual

Sets the coupling used for an input channel.

Parameters

i	Zero-based index of channel

Implements Oscilloscope.

◆ SetChannelOffset()

void MockOscilloscope::SetChannelOffset	(	size_t	i,
		size_t	stream,
		float	offset
	)

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.

◆ SetChannelVoltageRange()

void MockOscilloscope::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.

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)
range	Voltage range

Implements Oscilloscope.

◆ SetInterleaving()

bool MockOscilloscope::SetInterleaving ( bool combine )

overridevirtual

Configures the scope to combine channels.

This function may fail to enable channel combining if conflicts are present, check the return value!

Returns: True if channel combining is enabled, false if not

Implements Oscilloscope.

◆ SetSampleDepth()

void MockOscilloscope::SetSampleDepth ( uint64_t depth )

overridevirtual

Sets the sample depth of the scope.

Implements Oscilloscope.

◆ SetSampleRate()

void MockOscilloscope::SetSampleRate ( uint64_t rate )

overridevirtual

Sets the sample rate of the scope, in Hz.

Implements Oscilloscope.

◆ SetTriggerOffset()

void MockOscilloscope::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.

◆ Start()

void MockOscilloscope::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.

◆ StartSingleTrigger()

void MockOscilloscope::StartSingleTrigger ( )

overridevirtual

Arms the trigger for a single acquistion.

Implements Oscilloscope.

◆ Stop()

void MockOscilloscope::Stop ( )

overridevirtual

Stops triggering.

Implements Oscilloscope.
