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.

SCH - Model 5870 offers an on-screen digital readout of SCH in degrees of error referenced to the signal observed or an external reference for color framing checks.

LINE SELECT - Offers full raster line select with lines chosen from Fields 1/3, 2/4 or ALL. Field and line numbers appear on screen and a strobe is added to PIX MON OUT signals to highlight the selected line(s). Full waveform and vector manipulation is available in the line-select mode. Memory storage of up to 9 resettable field/line numbers provides instant recall for routine tests. Provision is made for remote control including recall of line presets.

UNIVERSAL POWER - Employ a switching mode power supply that accepts 90-250 V ac, 48-440 Hz to operate in any locality where ac power is available. In addition, dc power is standard and vehicle or battery power at 11-20 V dc is accepted. A battery mounting bracket, LC-2222, is available for battery operation from a BP-90 type battery.
