(2) Z Out
Outputs "H"-level TTL signals while it continues with sweep.
(3) Blanking Out
Outputs "H"-level TTL signals every sweep step, from the time when hardware setting is completed, till the next
step setting begins
(4) Marker Out
Outputs "H"-level TTL signals when the actual sweep matches the marker point which was set in the "Sweep
Parameter" menu.
