vectorscope

UpUp


This is a standalone (not rackmountable) Tektronix 520A NTSC vectorscope.

This unit powers up and functions. I have tested it using NTSC input from my digital video camera. (see pictures) It produces nice vector densities and other graphs when connected to an input, and circles and flat lines when not connected. The unit is exceptionally clean. 520A's are very easy to use.

It was recently calibrated (1999), the calibration seals are unbroken. A good working 520A like this one is hard to find. :SATISFACTION: From the tektronix info site:

Vectorscope 

     Luminance Amplitude 
     Chrominance Amplitude and Phase 
     Differential Phase 
     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.

 Time Base Displays
 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.

 Vertical Interval Test Signal Observation
 You can display vertical Interval Test Signals from front-panel selected
 lines of either field 1 or 2.

 Differential Gain and Differential Phase Measurements
 The two main chrominance signal distortions - differential gain and
 differential phase - can be measured.
This unit takes a standard computer power cable. It ships without one.
