Rare Anomaly
Board label: RARE_ANOM
Grid location: A10
Description: The two less-frequent
anomalies in this pulse train can show up on
high waveform capture rate oscilloscopes.
A half-height runt signal occurs
approximately every 838.8 ms. Use a Runt
trigger to isolate the signal.
A 25 ns (narrow) pulse appears in
approximately 838.8 ms. Use a Pulse Width
trigger to isolate the signal.
The pulse train is a repeating group of three
pulses. The three pulses are 100 ns, 200 ns,
and 100 ns wide, with a 100 ns low between
each pulse. The group repeats at a 1.6 μs
rate.
The anomaly is a group of four pulses. The
four pulses are 50 ns, 25 ns (narrow), 100 ns
(runt), and 100 ns wide, with a 100 ns low
between each pulse, except for a 25 ns low
before the narrow pulse.
