Users can also use the direction keys and knob to set the parameter value: use the
direction keys to move the cursor to select the digit to be edited and then rotate the
knob to change the number.
To Set Leading/Trailing Edge Time (Pulse)
Leading (rising) edge time is defined as the duration of the pulse amplitude rising
from 10% to 90% threshold, while Trailing (falling) edge time is defined as the
duration of the pulse amplitude moving down from 90% to 10% threshold (as shown
in the figure below).
The setting range of leading/trailing edge time is limited by the currently specified
pulse width limit (as shown in the formula below). DG1000Z will automatically adjust
the edge time to match the specified pulse width if the value currently set exceeds
the limit value.
Leading/Trailing Edge Time ≤ 0.625 × Pulse Width
Press Leading (Trailing) to highlight “Leading” (“Trailing”). Use the numeric
keyboard to input the desired value and then select the desired unit from the pop-up
menu.
 The Leading/Trailing Edge Time units available are sec, msec, μsec and nsec.
 Leading edge time and trailing edge time are independent from each other and
users can set them separately.
Users can also use the direction keys and knob to set the parameter value: use the
direction keys to move the cursor to select the digit to be edited and then rotate the
