The Module 'Scope' is designed for implementing oscilloscopes by creating Device Classes.
Device Class development
Supported parameters
An oscilloscope has many parameters that are needed before a certain configuration is reproduced. Sometimes it is easier to change parameters directly at the device. To not overwrite certain parameters when starting a measurment, we recommend to add "As is" to each ComboBox. In that case, the Device Class should not send any command to the oscilloscope.
TriggerSource
A ComboBox to provide possible trigger sources such as the channels of the oscilloscope or an external trigger in port
TriggerCoupling
A ComboBox to provide the trigger coupling that defines which mode is used to get triggered, e.g. it can be 'AC', 'DC', or high frequency ('HF').
TriggerSlope
A ComboBox to provide the trigger slope, e.g. a rising flank, a falling flank or both
TriggerLevel
A LineEdit to provide the trigger level at which the signal is recognized and the time is zeroed.
Acquisition
A ComboBox to provide how acquisition is done. Typically, the acquisition is done 'Continuous'. However, if the data related to a single trigger event needs to be measured, one should provide a mode like 'Single'.
Average
A ComboBox to provide typical values that can be used for averaging, e.g. 1, 2, 4, 8 ...
SamplingRate
A Line Edit to provide the numbers of sample per second.
TimeRange
A ComboBox to provide different modes that can be used to define the time span that is used for collecting the data.
TimeRangeValue
A LineEdit to get the number that is specifying the time range. For example, if TimeRange is 'Time range [s]' one can insert the time span of the captured signal. If the TimeRange is 'Time scale [s/div]' one has to insert the time span of a single division.
TimeOffsetValue
A LineEdit to get the offset time in seconds to shift x-axis horzitonally.
Channel
A CheckBox for each channel that tells you whether the channel should be used or not.
Channel_Name
The name that the user gave to channel . Please use it do define self.variables accordingly.
Channel_Range
The voltage range of channel .
Channel_Offset
The voltage offset of channel .
Channel_Impedance
The impedance value of channel .
Channel_ACDC
The coupling of channel .
Channel_Probe
The probe of channel . If not automatically detected one might have to provide options like '1:1' or '10:1'
