Operating Characteristics
50 Hz/ 625 Lines Same as 60 Hz/ 525 lines except that line numbering
is 1 to 318 for field 1 and 314 to 625 for field 2. This TV trigger made is
compatible with broadcast standards B, C, D, G, H, I, K, K1, L, and N.
User-Defined Mode Source is selected to be any one of the three
inputs. Trigger level is adjustable for the selected source. The trigger is
qualified with a high or low pulse that meets a selectable time range. The
trigger is an occurrence of a rising or falling edge of the source after the
qualifying pulse. The time settings for the qualifier are selectable from
20 ns to 160 ms. The trigger occurrence value is selectable from 1 to
16,000,000.
NOTE: All TV trigger modes require a clamped video signal for stable
triggering. Use the HP 1133A TV/Video Sync Pod to provide clamped video
output that can be used in conjunction with the oscilloscope’s TV triggering
capabilities.
