Introduction. D-2 servo observation. The 1750A-Series is useful in the composite edit suite, providing all 1740A-Series features, plus the Tektronix polar SCH display to match color subcarrier-to-horizontal sync timing and color framing among edit sources. 1740/1750-Series monitors are made through an on-screen menu in the 1740A/ 1750A-Series. The operator can also recall up to 10 front-panel setups through the 1740A/1750A Series Waveform/Vector Monitor User Manual VOLTAGE/TIMING VARIABLE GAIN LINE SELECT.

The optional 1700F05 rack adapter allows two Tektronix half-rack instruments to be mounted side-by-side in a rack. It is adjustable so that the instrument can be closely aligned with other equipment in the rack. Focus, scale illumination, signal intensity, readout intensity, and trace rotation are set through the CRT menu.

Making Measurements.
Basic Measurements Basic Measurements contains 1740A/1750A-Series graticule descriptions, followed by specific measurement procedures. This monitor uses an internal graticule, which combines wa- veform and vector markings. The internal graticule scales are on the same plane as the CRT phosphor, eliminating par- allax errors. The graticules are also marked for K-Factor tolerances and linear-distortion measurements. These measurements will be described later in this section.
