Advanced Capture Setting
Capture mode setting
Asynchronous mode:
Asynchronous mode, also known as timing Analyzer, is based on the internal clock as a
sampling frequency. It is recommended that the sampling frequency be set at about 10
times the signal to be measured, with the minimum not less than 5 times. Any rates
lower than 5 times will cause distortion. Asynchronous sampling will cause sampling
error from the actual capture to the signal, with the error time being the reciprocal of the
sampling frequency.
The default mode is to capture the signal at the sampling frequency. If you want to
increase the signal capture frequency, you can add a qualifier by selecting CK0 and
setting a channel to be 0 or 1. For example, when Chip Select is 0 to allow to capture the
signal, you can select the asynchronous mode (recorded when CK0 = 0) to add the
qualifier. After the qualifier condition is selected, the device will automatically turn on
the transpose mode to capture the signal.
Synchronous mode:
Synchronous mode, also known as the state Analyzer, uses the external input clock as
the sampling frequency. The channel marked with CK0 on the signal line is the external
clock input channel. When the external clock stops, the signal capture will also stop,
forming a synchronous operation between the two.
Easy setting
CK0 is used as the input clock when it is at the edge of Rising / Falling / Either.
