in the Delay field, and is set by using the knob or the keypad.
deskewing To cancel or nullify the effects of differences between two different internal delay paths for a signal. Deskewing is normally done by routing a single test signal to the inputs of two different modules, then adjusting the delay path to one of the modules so that both modules recognize the signal at the same state at the same time.
don’t care Signifies that the state of the signal, high or low, is not rele- vant to the measurement. That is, the analyzer will ignore the state of this signal when determining whether a match occurs on an input label. Don’t cares are represented by the X character in analyzer resource terms.
edge mode In the oscilloscope, this is the trigger mode that causes a trigger based on a single channel edge (either rising or falling).
glitch/edge terms Timing ana- lyzer resources that allow detection of transitions on a signal. A glitch/edge term can be set to detect a rising edge, falling edge, either edge, no edge, or glitch (very short duration pulse) on an input signal. See also glitch.
glitch A glitch is defined as two or more transitions crossing the logic threshold between consecutive tim- ing analyzer samples.
high The
horizontal position See delay field.
horizontal sweep speed In the oscilloscope, the time value that de- termines horizontal scaling of the waveform to be displayed on the screen. It is measured in seconds per division and is viewed in the s/Div field. It is set by using the knob or the keypad.
immediate mode In the oscillo-
scope, the trigger mode that does not require a specific trigger condi- tion (that is, an edge or a pattern).
input field In the oscilloscope, the field that allows you to select a chan- nel for vertical scaling.
