Tektronix rackmount ntsc vectorscope model 520A
Tektronix 520A NTSC Vectorscope
Graphically displays the phase and amplitude of TV chrominance signals on polar coordinates in a vector presentation; measures luminance amplitude, differential gain and differential phase.
In dual-channel operation, successive samples of channels A and B are displayed on a time-shared basis.
Red (R), Green (G), Blue (B), and Luminance (Y)
Provides a luminance channel that permits the separation and display of the luminance (Y) component from the composite color signal.
Differential Gain and Differential Phase Measurements
The two main chrominance signal distortions - differential gain and differential phase - can be measured.
