HDO6000 High Definition Oscilloscope
Determining Differential Time Measurements
The instrument enables accurate differential time measurements between two traces: for example,
propagation, setup and hold delays (see figure).
If included in your oscilloscope, parameters such as Delta c2d± require the transition polarity of the clock
and data signals to be specified.
Moreover, a hysteresis range may be specified to ignore any spurious transition that does not exceed the
boundaries of the hysteresis interval. In the figure, Delta c2d- (1, 2) measures the time interval separating
the rising edge of the clock (trigger) from the first negative transition of the data signal. Similarly, Delta
c2d+ (1, 2) measures the time interval between the trigger and the next transition of the data signal.
