5212 NTSC/PAL Vectorscope
Operating automatically in NTSC or PAL, the 5212 overlays Vector displays for 4 signals (3 input
channels plus an external reference.) A touch on Auto Phase automatically zeros burst to the -B-Y (-U)
axis, using the reference chosen from any channel or an external reference. Digital Phase Readout
makes it easy to measure precise Phase differences between channels. Of particular value is semi-auto-
matic setup for high-resolution measurements of Differential Phase and Gain.
Other features include menu selected calibration for signals with or without setup and for 75% or
100% Color Bars. A +V key inverts -V signals for a less cluttered PAL display. Up to 10 front panel
setups may be stored for instant recall, and remote control with line select strobe is provided via con-
nection to the 5222 Waveform monitor. X-Y operation for stereo monitoring is standard and is
accessed via a rear panel connector.

5870/5872A Waveform Monitor/Vectorscope
Combos with Line Select
Combining the standard features of a Waveform monitor and Vectorscope in a single half-rack package,
the 5870 and 5872A add 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 5x Vertical Gain multiplier, 200 ns/major division fastest Time Base and wide-range cen-
tering 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. Both employ a
switching mode power supply that accepts 90-250v 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 11-20v DC is accepted.
Line Select—Both offer 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 con-
trol, including recall of line presets.
Where line select is a must — as in satellite/STL operations, or to meet the new proof-of performance requirements for cable systems, the
5872A is an ideal choice. It offers full line-select, as well as the preset line selection features of Model 5870 (but without SCH capability).
The preset mode permits routine call-up of designated lines carrying the vital test signals needed to gauge performance and to meet the
needs of FCC Measurement of DG/DP and Chroma/Luminance delay. All of the features of the 5872A are retained, including the univer-
sal power supply and DC power (11-20v DC standard).

5870 Only
The 5870 (only) 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.
