Latch Function

Users can set the specified signal in the paralleling bus as the sampling site reference to analyze the data.

In the Latch setting window(see figure 1), users can activate the Latch function and set its channel and condition (Rising Edge, Falling Edge, Either Edge), then click OK. The analysis result will be displayed in the waveform display area.

Figure 1: Latch setting window.


For example: If some signal under test is 4 bits paralleling bus, but whether the data is effective or not is judged with EN. Then users can use the Latch function and set the channel as EN and the condition. See figure 2 for the result after setting finished.
