    Tektronix r520A NTSC Vectorscope
    The r520A series enables measurement of the chrominance signal and distortions thereof to be made with a high degree of precision. Measures luminance amplitude, chrominance amplitude and phase, differential gain, differential phase etc.
    =====================================
    The r520A NTSC Vectorscope graphically displays the phase and amplitude of television chrominance signals on polar coordinates in a vector presentation. Measures luminance amplitude, differential gain, and differential phase. NTSC configuration. Features: Vectorscope, Luminance Amplitude, Chrominance Amplitude and Phase, Differential Phase, and Differential Gain. Vector display shows the relative phase and amplitude of the chrominance signal on polar Dual Vector Displays. In dual-channel operation, successive samples of channels A and B are displayed on a time-shared basis. The linear time base operates at the line rate. 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. You can display vertical Interval Test Signals from front-panel selected lines of either field 1 or 2. The two main chrominance signal distortions - differential gain and differential phase - can be measured.
