Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Conventional chrominance-to-luminance gain and delay measurements are based on analysis of the baseline of a modulated 12.5T pulse. This pulse is made up of a sine-squared luminance pulse and a chrominance packet with a sine-squared envelope as shown in the figure below. This waveform has many advantages. First it allows for the evaluation of both gain and delay differences with a single signal. It also eliminates the need to separately establish a low-frequency amplitude reference with a white bar.
Since a low-frequency reference pulse is present along with the highfrequency information, the amplitude of the pulse itself can be normalized.
The HAD of 12.5T was chosen in order to occupy the chrominance bandwidth of NTSC as fully as possible and to produce a pulse with sufficient sensitivity to delay distortion.

Industry:Entertainment
The degree to which the coating adheres to the base film.
Anchorage may be checked by measuring the force required to separate the coating from the base film by means of a specially designed plow blade or, more simply, by determining whether the coating can be peeled from the base film by means of ordinary pressure-sensitive adhesive tape.
