The Online Summation Window provides all channels and all digital triggers from the recorded file. Two mean curves can be plot simultaneously and the mean is calculated from all recorded and selected data pieces, not only from a circular buffer. The third plot is the difference between the first two plots. If a reflex and a background condition is plot, the third plot shows the influence from the reflex without background. Which trigger condition is subtracted from each other can be choosen. Shown Parameters Check the position of the H-Cursors. From the signal between these H-Cursors the parameters are calculated. Reflex size is the amplitude between the H-Cursors. Delay is the mean delay in respect to the digital trigger. If the maximum muscle reflex is known, this number can be input into M max and the parameter %M max automatically calculates the recent reflex amplitude compared to M max. If the cursor position has changed, a new calculation can be triggered with the Refresh button. The units used in this window are all physical units. Use therefore the calibration values in the instruments to define the equivalent to 1V to a physical unit, e.g. 1V at the A/D converter = 5mV electrical signal before amplification. Press New Selection to return to the selection of digital triggers and signal pieces. This is useful if you want to process one trigger condition after each other with slightly different cursor positions. This can be done without leaving the online processing. Press Refresh to re-calculate the reflex sizes and delays. Especially when moving the cursors this might be necessary. After pressing Save+Repeat or Save+Exit a file selection box appears and you can choose a name to write text files with all relevant information for further examinations with Excel. The file extension will be defined automatically and represents the digital trigger number. Choosing Save+Repeat will not exit the processing window so that you have the possibility to do some changes and once more save the result without leaving the window. With the activation of Append Graphs each new selection of channel or trigger will be added to the existing plot. This function can be used to show differences between two different trigger conditions in the same window.
