Add new waveform

Put a new, empty waveform into the selected display (A or B). The waveform currently present there will be hidden and you may access it again via pop-up menus on the right margin or via tabs at the bottom of the window.

· Use Waveform Remove waveform to undo.

Shortcut: ctrl- N

Remove waveform

Remove and delete the selected waveform. Replace it with a first available from the waveform list or a new, empty one.

· Cannot be UNDONE!

Edit name...

Change the name of the active waveform.

Shortcut: ctrl- L

Max amplitude...

Calls a dialog to set the maximum amplitude of the selected waveform in volts that corresponds to 100 units (full scale) of the amplitude. Same result can be achieved by clicking in the max-amplitude display and typing a value.

To fine-tune the value use up/down arrow buttons on the right hand side of the display. They change the value in 0.1V steps. The step can be increased to 1V by holding shift key.

The DC offset control below allows offsetting the generated waveform. This is not shown on the display, use oscilloscope to monitor the output signal. The sum of offset and max waveform amplitude is limited to the maximum amplitude of the signal that can be generated by your WFG model or the set amplitude limit.

Group waveforms...

Join waveforms in the groups in order to control the max amplitude simultaneously for all waveforms within the group. The choices are: free, column, row, arbitrary group X, Y, Z. The symbol of the group will be displayed on the left margin of the window, near the lower part of the amplitude axis.

Unless the current waveform is the first member of the group, its maximum amplitude will automatically be adjusted to the value defined by existing group members.

Max amplitude change of any member of a group propagates to the remaining members.

Shortcut: ctrl- U

Set amplitude limit

This command provides an extra security against accidentally increasing the signal amplitude over the allowed value for the device under test. When the program starts, this limit is set by default to 100V (i.e. the maximum).

Functions >> Ramp...

A single-slope ramp will be automatically created in the selected range of pulses. (Hence, before invoking this command you have to create a desired number of pulses and select them). The ramp may be unipolar or bipolar, rising or falling, the amplitudes and pulse width may be coupled (see Coupling for explanation). The widths of involved pulses will be equal to the value set in the dialog.

Functions >> Sine wave...

Create a sine wave over the selection of pulses. (Hence, before invoking this command you have to create a desired number of pulses and select them). In the dialog you have to state starting angle in degrees, total length in degrees, pulse width and also if you want couplings between pulses.

Functions >> DC-waveform...

Create a DC waveform. It will be as long as the existing waveforms, have amplitudes of all pulses coupled together and initially zero volts. A dialog asks you to name the waveform.

Duplicate waveform

Create a new waveform exactly the same as the active one. Hide the original waveform and display the copy instead.

Since the new waveform is not associated with any output channel, no additional data will be sent to the generator.
