Tektronix T1 Values, T2 Values, DCD Values

Appendix B: Automatic Measurements Supported
B-8 CSA7000 Series, TDS7000 Series, & TDS6000 Series Instruments User Manual
The T1 values are vertical and horizontal values associated with the leftmost
crossing point. These areas are used to establish the following directions:
HTCross1mean, the horizontal mean of the left crossing point at TCross1
HTCross1sigma, the horizontal standard deviation of the left crossing point
at TCross1
HTCross1p-p, the horizontal peak-to-peak deviation of the left crossing point
at TCross1
HPCross1mean, the vertical mean of the left crossing point at PCross1
The T2 values are vertical and horizontal values associated with the rightmost
crossing point. These areas are used to establish the following directions:
HTCross2mean, the horizontal mean of the right crossing point at TCross2
HTCross2sigma, the horizontal standard deviation of the right crossing point
at TCross2
HTCross2p-p, the horizontal peak-to-peak deviation of the right crossing point
at TCross2
The duty cycle distortion (DCD) values are horizontal values associated with the
rightmost crossing point at 50% of the eye height. These areas are used to
establish the DCDp-p, the horizontal peak-to-peak deviation of the left crossing
point at half the height of the eye.
