The Stats module can compute and display statistics of the inputs waveforms. Available statistics are - min, max, mean, standard deviation, peak-peak & max cycle-cycle. Either statistics for the current processing cycle or accumulated over multiple processing cycles or both can be selected. Time stamps of min, max & max cycle-cycle statistics are available for the current processing cycle. The Stats module supports the graphical user interface as explained below.

Graphical Interface

You can drag & drop a min, max or max cycle-cycle statistic or its time stamp from the stats window to plot window in order to center the plot horizontally around it.

Ports

CH1-4

Connect the input signal(s) to the CHx input ports.

Multi-Acquisition Stats

Max

It is the maximum value for a given measurement accumulated over multiple acquisitions from the last reset or start of the software, whichever is later.

Min

It is the minimum value for a given measurement accumulated over multiple acquisitions from the last reset or start of the software, whichever is later.

Pk-Pk

It is the maximum of all peak to peak per cycle values for a given measurement accumulated over multiple acquisitions from the last reset or start of the software, whichever is later. This is usually less than (Max - Min) and is equal to (Max - Min) if Max and Min occur in the same cycle.

Mean

It is the mean value for a given measurement accumulated over multiple acquisitions from the last reset or start of the software, whichever is later.

SD

It is the standard deviation for a given measurement accumulated over multiple acquisitions from the last reset or start of the software, whichever is later.

Pop

It is the total population for a given measurement accumulated over multiple acquisitions from the last reset or start of the software, whichever is later.

Current Acquisition Stats

CMax

It is the maximum value for a given measurement computed in the most recent acquisition.

CMin

It is the minimum value for a given measurement computed in the most recent acquisition.

CPk-Pk

It is the maximum of all peak to peak per cycle values for a given measurement computed in the most recent acquisition.

CMean

It is the mean value for a given measurement computed in the most recent acquisition.

CSD

It is the standard deviation for a given measurement computed in the most recent acquisition.

CPop

It is the total population for a given measurement computed in the most recent acquisition.

CStats Occurrence Time

T_CMax (Tcmax)

It is the time at which CMax occurred.

T_CMin (Tcmin)

It is the time at which CMin occurred.

T_CPk-Pk (Tcpk-pk)

It is the time at which CPk-Pk occurred.

Popup Menu

Right clicking on the stats module displays the popup menu.

Stats (Multi-Acquisition)

Shows the multi-acquisition statistics. Multi-acquisition statistics are accumulated on each acquisition/measurement cycle till reset from the control toolbar.

CStats (Current Acquisition)

Shows the current acquisition statistics. These statistics are refreshed on each acquisition/measurement cycle.

Tcstats (CStats Occurrence Time)

Shows the time at which the Min, Max & Pk-Pk of current acquisition occurred.

Transpose

Click to turn transpose ON or OFF for better view. Turning transpose ON swaps the rows and columns of the active stats window.

Reset Selected

Resets the currently selected input's statistics.

Reset All

Resets statistics for all inputs.

Copy (Comma Separated)

Copies the stats window to clipboard in csv format. Press Ctrl-v key combination in other applications (if supported) to paste the data.

Copy (Tab Separated)

Copies the stats window to clipboard in tab separated format. Press Ctrl-v key combination in other applications (if supported) to paste the data.

Save

Click to save all statistics to last saved file.

Save As

Click to select a file or enter a filename to save all statistics to.
