8. Chapter 4 Function Generators Chapter 5 Sources Chapter 7 I Os Chapter 8 Sinks Chapter 9 Sources are objects that output data This can be constant data like in the demo source or any other kind of data The most important sources are the instrument channels Chapter 6 6 4 6 4 1 6 4 2 6 4 3 I Os also called processing blocks are objects with input s and output s They produce data at their output s that is somehow related to their input s A Low pass filter I O for example filters the input data The output of a processing block is again a source which can be connected to other I O blocks or to graphs Sinks are the opposite of a source Instead of supplying data they accept it just like an 1 0 object The difference is that a sink does not have an output source Handling objects Creating You can create a new source I O or sink by right clicking on the root item in the object tree and selecting the object of your choice from the popup menu In figure 6 1 the I Os item is clicked with right mouse button After constructing objects you can change their settings via their popup menu In figure 6 2 two SoftGen sources and an Add Subtract I O object are created The signal type of the second SoftGen source is set to to square Cloning Another way to create objects is to clone existing objects When you clone an object a new object of the same type will be created with the same settings and data as

Divide I O object to get the power You can also use a Low pass filter to filter your measure ments The easiest way to learn about the possibilities of the objects is to try Just create some objects connect them to each other and see what happens You can also have a look at the examples in section 6 5 to get you started Objects 6 2 Object tree The object tree is situated at the left side of the main window of the application It contains the measuring instruments function generators and other objects constructed in the ap plication the data sources I O blocks and data sinks which all can be used in combination with the measured data Via the object tree you can create different in and out put blocks see section 6 4 1 and connect them see section 6 4 3 When sources are connected to an object this is indicated by the caption of the object in the tree For exam ple when two channels of a Handyscope HS5 are connected to a Add Subtract IJO object its caption will change to Add Subtract1 HS5 27917 Ch1 HS5 27917 Ch2 You can hide or show the object tree by pressing the symbols lt and respectively You can export data to different file formats via the popup menu of the sources and I Os in the object tree Read how to do this in section 10 4 6 3 Object types The different objects are divided into groups that are visible in the object tree Each group of objects is described in its own chapter Instruments
10. With the resampler the signal s that can be represented with a lower sample frequency can be resampled to a lower sample frequency An example when using a RPM I O to determine the speed of an engine the sample frequency must be around 10 kHz or higher to get the accurate rpms Once the speed has been determined it can be resampled to a lower sample frequency for example 10 Hz because the speed will vary Chapter 8 8 14 relatively slow This decreases the amount a memory or file size by a factor 1000 You can enter the ratio between output sample frequency and input sample frequency directly via the resampler s popup menu It is also possible to enter the output sample fre quency in the menu In that case the ratio is calculated automatically Different resampling methods are available e normal The input data is sampled at the output sam ple times without any interpolation e linear The linear interpolated input data is sampled at the output sample times e average When the ratio is smaller than 1 the mean value of several samples of the input data is used for each output sample When the ratio is greater than 1 the linear method is used Data collector GH Use the data collector object when performing streaming measurements During streaming measurements data arrives in blocks with a size equal to the instrument s record length To form a continuous stream of data these blocks must be appended to each o
