  • Notes

  • The 1721 is an 8-1/2”--wide by 5-1/4”--high Vectorscope,
    (System I, B, etc., PAL) versions can be powered from an ac source or,
    with the addition of a field upgrade kit (1700F10), from 12 Vdc. The crt occupies approximately two-thirds of the front-panel area. The inputswitching allows for the display of Channel A, Channel B, or both inputs. Synchronization can be either internal or external. The 1721 offers a choice of individual displays of vectors or XY or both.
    The XY display, with accompanying graticule scale, allows this vectorscope to
    be used for stereo audio monitoring. In addition to the usual color bar amplitude and phase relationships, the vector display can also be used to make differential gain and phase measurements. The 1721 has the +V display that is used to check PAL system color encoders. Full 360°phase shift and a test circle are also included in these vectorscopes.

    Stereo audio input for XY display is balanced line through the rear-panel REMOTE connector.
