point for connecting the cable to the monitor main sweep gate

output signal.

(f) DELAYED SWP GATE OUTPUT Connector. Provides the

connecting point for connecting the cable to the monitor delayed

sweep gate output signal.

(g) DELAYED TRIG OUTPUT Connector. Provides the connecting

point for the cable to the monitor delayed trigger output signal.

(h) Power Input Connector and Cable. Provides for the

connection of the external power cable to the oscilloscope.

d. Operation. The paragraphs that follow contain the

procedures and general information required to operate the

AN/USM281C oscilloscope. Included in this discussion are the

turnon procedures, operating procedures, and the turnoff

procedures. Note that it is not necessary that all three plug

in compartments be filled in order to operate the oscilloscope.

However, at environmental extremes, electromagnet interference

may be radiated into or out of the oscilloscope through an empty

compartment. If a plugin unit is not available, it may be

necessary to cover an empty compartment with a blank panel.

(1) TurnOn Procedures. Prepare the oscilloscope for

operation as follows:
