PHA ACQUIRE START/STOP
External PHA Start/Stop input connector, BNC. TTL compatible, software selectable
logic polarity for active-high or active-low. Two basic modes are supported, pulse or
level, programmable via software.
•
Pulse (DSA-2000) mode
– Requires TTL pulse, width > 50 ns, positive or
negative edge triggered, software selectable. Requires that the acquisition has
been armed through Start Acquire command.
Start
– first pulse received will begins acquisition storage. Subsequent
pulses are ignored.
Stop
– if acquisition is already active, first pulse received will stop
acquisition; subsequent pulses are ignored. No action taken if acquisition
was off when first pulse was received.
Start and Stop
– first pulse received will begins acquisition storage.
Second pulse received will stop acquisition. Subsequent pulses will be
ignored.
•
Suspend/Resume mode
– Requires TTL level, active high or active low,
software selectable. Requires that the acquisition has been armed through
Start command. Active signal begins or resumes acquisition. Inactive signal
suspends acquisition.
Either mode requires that the acquisition has been armed with start-acquire
command.
