Version 1.0.20 of the Multi Channel software is now available for download. A demo version is also available, which can be used without connecting measuring instruments.

Many changes have been made to the Multi Channel software. For example, new analyzer capabilities have been added:

• CAN analyzer I/O: extracts contents of CAN bus packets from analog CAN bus measurements. Several CAN fields are extracted and can be displayed in a Data grid sink.
• Pulse decoder I/O: decodes quadrature encoder signals.
• Compression test sink: this automotive analyzer calculates relative compression of all cylinders of a combustion engine from the starter current.

Single channel instruments as well as instruments with two or more channels can be used as CAN analyzer. To be able to analyze fast CAN buses and to analyze the CAN signal quality, use of an instrument with a maximum sample rate of 50 MS/s or higher is recommended. The following instruments are recommended for use as CAN analyzer:

• Handyprobe HP3-100
• TiePieSCOPE HS805
• Handyscope HS4 DIFF-50
• Handyscope HS4-50
• Handyscope HS3-50 or faster.

A Data grid sink has been added for displaying different kinds of data in a table. It can for example be used to display the results of a CAN analyzer I/O or Pulse decoder I/O. The figure below shows a Data grid sink with decoded CAN data measured on the CAN bus of a car.

Instrument and channel toolbars can be customized by dragging different items on or off an example toolbar in Settings->Instruments->Toolbar. Several default schemes may be chosen. Scheme Classic for example contains V/div and time/div buttons and labels. Changed schemes can be saved for later use. Toolbar icons can be set to arbitrary sizes.

Sources can be added to graphs more easily:

• When a time based source is added to a graph containing one or more data collectors, the user is asked whether a data collector should be created for this source. This means that channels can directly be added to a transient recorder graph.
• A graph in frequency domain now accepts time domain sources. An FFT I/O is inserted automatically. This means that channels can directly be added to a spectrum analyzer graph.
• When a source is dragged onto a spectrum analyzer graph and all lines in the graph are logarithmic, the axis for the new line is set to logarithmic as well.

This is a list of some of the other changes:

• User can limit number of channels that is used for the quick functions in settings.
• Added option to Disk writer sink to store one of every N records. By default all are still stored.
• Duty cycle and Duty cycle inverted measurements added to cursor window and Meter sink.
• Default enabled measurements of Meter and cursor window can be changed in the settings.
• Timebase can now be changed with time/div buttons and time base resolution buttons. See Settings->Instruments->Toolbar.
• Instruments can be extracted from a combined instrument.
• Files in the recently used file list are grayed when not accessible.
• Instrument and channel toolbars can be rearranged and layout can be saved.
• Main toolbars (main menu, file, quick functions) can now be hidden and rearranged.
• Presamples, trigger level and trigger hysteresis can now be entered in different units besides as a percentage.
