6. -Width: indicates the time between the threshold middle value of a falling edge 
to the threshold middle value of the next rising edge. 
7. +Duty: indicates the ratio of the positive pulse width to the period. 
8. -Duty:indicates the ratio of the negative pulse width to the period. 
9. Tvmax:  indicates  the  time  that  corresponds  to  the  maximum  value  of  the 
waveform (Vmax). 
10. Tvmin: indicates the time that corresponds to the minimum value of the 
waveform (Vmin).   
 
Note: The default values for threshold upper limit, threshold middle value, and 
threshold low limit are 90%, 50%, and 10%, respectively. You can press Measure 
→ Setting to enter the sub-menu to set the parameters. 
 
 
Count Values 
 
1. Positive Pulse Count: The number of positive pulses that rise from under the 
threshold lower limit to above the threshold upper limit. 
 
 
 
2. Negative Pulse Count:  The number of negative pulses that fall from above 
the threshold upper limit to below the threshold lower limit. 
 
 
3. Rising  Edge  Count:  The  number  of  rising  edges  that  rise  from  under  the 
threshold lower limit to above the threshold upper limit.
