The RS-170A specification states that the
relationship between horizontal sync and
subcarrier of field one, line 10 shall have a zero
crossing in the up cycle of subcarrier and be in
coincident with the leading edge of horizontal sync
and have a tolerance of ±40 degrees. The
Phaselcon is capable of displaying a much tighter
tolerance, in the order of ±2 degrees of Subcarrier
phase and ±2nS of Horizontal timing. In addition to
these features, the IEC-835 has a unique ability to
display Subcarrier distortion. The sine wave
display is referenced to the actual incoming burst.
All display timing is reference locked in such a
completely unique way that parameter drift is all
but eliminated.
SPECIFICATIONS
The IEC-835 displays an extremely accurate graphics representation of the video source being measured.
