5.2 Pattern Synchronized Output Period5.2.1 Pseudorandom pattern
Period = × (2N-1) × 128
N=7, 9, 11, 15, 20, 23, 31
(Where pulse width = × 64, plus pulse)
5.2.2 Programmable pattern
(1) Data pattern, alternate pattern
(a) Data length = 65536 or less
Period = × (least common multiple between 128 and data length)
(Example 1) Data length = 8
Period = × 128
(Example 2) Data length = 10
Period = × 640
(b) Data length > 65536
Period = × (data length)
(2) Zero sub pattern
Period = × 2NN=7, 9, 11, 15
(3) Pulse width
For any of the programmable patterns above, the pulse width = × 64. The output signal polarity is
plus pulse.
Note: For the alternate pattern, the synchronization output is output in basic data length units. As a result, when the data
output is monitored on a sampling oscilloscope, patterns A and B are shown overlapping.
To prevent patterns A and B from overlapping, connect A/B TIMING OUTPUT on the rear of the instrument to the
trigger of the oscilloscope through an ECL terminator.
