5. Interp

Press this softkey to enable or disable the interpolation between the defined
waveform points.
 Off: The waveform editor will hold a constant voltage level between two

points and create a step waveform.

 Linear: The waveform editor will automatically connect the two defined

points with a straight line.

6. Edit Points

Define a waveform by specifying the time and voltage of each waveform point.
Press this softkey to enter the “Edit Points” interface.
 PointID: Set the ID of the point to be edited. The default is 1. You can

use the numeric keyboard or direction keys and knob to modify this
parameter.

 Time: Set the time of the current point in a period. This setting is limited

by the times of the previous and the next points. Note that the time of
point 1 is fixed at 0 s.

 Voltage: Set the voltage of the current point in mV or V. The range of the

voltage is limited by the “High VLimit” and “Low VLimit”. Note that the
waveform editor will automatically set the voltage of the last point to the
voltage of point 1 to create a continuous waveform.

 Insert Point: Insert a waveform point at the middle position of the

currently edited point and the next edited point.

 Delete Point: Delete the current point from the waveform and connect

the remaining points using the current interpolation method. Note that
point 1 cannot be deleted.

7. Edit Block

Define a waveform by editing the time and voltage of the start and end points
and automatically setting the points between them through linear
interpolation. Press Interp to select “Linear”, and then press this softkey to
enter the “Edit Block” interface. Note that if “Linear” is not selected in Interp,
this menu is grayed out and disabled.
 X1: Set the ID of the start point of the block (namely the time position of

the start point). Note that this value should be lower than the “Init Points”
and be equal to or lower than X2.

 Y1: Set the voltage of the start point in mV or V. The setting range of
