Combining the standard features of a waveform monitor and vectorscope in a single half-rack package, Model 5870 adds a number of powerful measuring advantages. Among these are the ability to overlay waveform and vector displays from two input signals for precise level, timing and phase matching. A X5 vertical gain multiplier, 200 ns/major division fastest time base and wide-range centering controls permit close inspection of all parts of the waveform for high resolution adjustments. The use of the decoded R-Y signal facilitates easy, high-resolution measurements of differential phase and gain. Chroma and IRE filters may be inserted on a full-time or line-shared basis.
