Measurement Parameter
Click on the function navigation icon
to open the function navigation. Then click
on the Measure icon to enter the measurement setting menu. You can set the
measurement source, enable or disable the all measurement function, the statistical
analysis function, and etc. You can also quickly make measurements for 41 waveform
parameters. The measurement results will be displayed on the screen. The
measurement results on the screen are always marked in the same color as the
current measurement channel. You can also click the auto measurement label
"Measure" at the top of the screen to enter the measurement setting menu.
Note: If there is no signal input for the current source or the measurement result is
not within the valid range (too large or too small), then the measurement results are
invalid, and "*****" is displayed on the screen. Please re-input the signal or set the
signal.
Time Parameters
Figure 6-1 Time Parameters
1． Period: defined as the time between the middle threshold points of two
consecutive, like-polarity edges.
2
． Frequency: defined as the reciprocal of period.
3
． Rise Time: indicates the time for the signal amplitude to rise from the threshold
lower limit to the threshold upper limit.
4
． Fall Time: indicates the time for the signal amplitude to rise from the threshold
upper limit to the threshold lower limit.
5
． +Width: indicates the time between the threshold middle value of a rising edge
