[QuadList] Sunday Trivia Questions--Why is there a 15-line mode on some WFM monitors, and how is it used?--

[Jeff Booth]

Each video head records/plays 15 lines. The 15 line display (from my very
distant memory) it was best used on demod out to check timebase stability,
jitter, sync pulse shape and eq. Also chroma phasing/diff phase and diff
gain (head by head) - although this was on colourtec out, prior to station
syncs being reinserted to the video.

 

Do I win the prize?
