Specifications and Characteristics
Operating Characteristics
State Trigger
After selecting any front panel channel or external trigger input as a clock, a
pattern is specified using any of the remaining front panel inputs. The user
may specify that a trigger will occur on the rising or falling edge of the input
specified as the clock, when the pattern is present or not present. Setup time
for the pattern with respect to the clock is 10 ns or less and hold time is zero.
Delayed Trigger
Event-Delayed Mode The trigger can be qualified by an edge, pattern,
time qualified pattern, or state. The delay can be specified as a number
of occurrences of a rising or falling edge of any one of the selected
channels. After the delay, an occurrence of a rising or falling edge of any
channel or external trigger inputs generates the trigger. The trigger
occurrence value is selectable from 1 to 16,000,000. The maxirmum edge
counting rate is 70 MHz.
Time-Delayed Mode The trigger can be qualified by an edge, pattern,
or state. The delay is selectable from 30 ns to 160 ms. After the delay, an
occurrence of a rising or falling edge of any one of the selected channels
or external trigger generates the trigger. The trigger occurrence value is
selectable from 1 to 16,000,000. The maximum edge counting rate is
70 MHz.
TV Trigger
60 Hz/525 Lines Trigger source is selected to be any one of the four
inputs (three inputs in two channel models). Trigger level is adjustable
for the selected trigger source. Polarity is selected for positive or
negative synchronizing pulses. A trigger occurs on the selected line and
field of a 2/1 interlaced composite video signal. Line numbering is 1 to
263 for field 1 and 1 to 262 for field 2. This TV trigger mode is
compatible with broadcast standard M.
