Undo the last operation. The name of this item changes according to the last task performed (for example: Undo amplitude change, Undo paste, etc.). If the text is dimmed - the operation cannot be undone.
Copy the selected sequence of the pulses from the active waveform (A or B).
Clear the sequence (i.e. set the amplitude of pulses included in the sequence to zero).
Copy the selected sequence of the pulses from the active waveform to the private clipboard of the program (you cannot paste it into any other program, the system clipboard is used for text editing only).
Paste the content of the program's clipboard (prepared by Copy or Cut commands) into the active waveform starting at the selected pulse. The waveform will be extended if needed (zero-amplitude pulses will be appended to all waveforms):
You can override existing amplitude and/or timing information according to settings in 'Preferences' dialog. Click on a corresponding check-box. You can make your choices permanent by checking 'Remember and do not ask again'. You can then access this dialog again using Preferences item described below.
Clear the selected sequence of the pulses in the active waveform (i.e. set the amplitude of the pulses included in the sequence to zero).
Insert a new pulse before the selected one (or the beginning of the selected sequence) into all waveforms. The pulse amplitude will be zero in all waveforms. The width of the inserted pulse will be equal to the width of currently selected pulse.
Insert a number of new pulse before the selected one (or the beginning of the selected sequence) into all waveforms (see above).
Copy the selected sequence of the pulses from the active waveform .
Perform Duplicate command N times. You will be prompted for the value of N.
Invert all pulse amplitudes within the current selection in the active waveform. If anyone of the pulses is coupled (cf. Coupling), its coupling parameters will be adjusted accordingly.
Invert all pulse amplitudes in the active waveform. If anyone of the pulses is coupled (cf. Coupling), its coupling parameters will be adjusted accordingly.
Invert all pulse amplitudes within the copy. If anyone of the pulses is coupled (cf. Coupling), its coupling parameters will be adjusted accordingly.
Revert the order of pulses in the copy (the last pulse becomes the first and the first becomes the last one, and so on).
Roll marked selection in the active waveform to the left or right. Only the amplitudes will be shifted, the timing will not move. You will be prompted for the direction and number of pulses.
Example : 'roll right by 2 pulses' means that the following operation will be performed twice: the last pulse will be moved to the first position and the remaining pulses will be shifted right by one slot.
Shortcut: Ctrl-alt-shift left/right arrow. First time the dialog will ask you the number of steps, that number will then be used always. Choose Roll selection from the menu to get the dialog again.
Roll the active waveform to the left or right. Only the amplitudes will be shifted, the timing will not move. You will be prompted for the direction and number of pulses.
Example : 'roll right by 2 pulses' means that the following operation will be performed twice: the last pulse will be moved to the first position and the remaining pulses will be shifted right by one slot.
Shortcut: Ctrl-alt- left/right arrow. First time the dialog will ask you the number of steps, that number will then be used always. Choose Roll waveform from the menu to get the dialog again.
Common settings for roll selection and roll waveform commands.
Reduce/enlarge the amplidudes of selected pulses in the active waveform by a factor set in percent. Coupled pulses cannot be present in the selection.
Call the dialog to set the way the Paste command should be performed - you can paste amplitudes or timing information or both. You may also chose to be asked before each paste.
