two other available channels and triggers only if
their conditions are met. Each channel can have a
value of high (H), low (L), or ”don’t care” (X). A
value is considered high if the channel input
voltage is greater than the specif ied threshold
voltage; a value is considered low if the channel
input voltage is less than the specified threshold
voltage. Use the ”don’t care” selection for any
channels that will not be used as part of the
pattern. (Logic qualification is only available on t he
