TEST CONDITIONS

3-11. Unless otherwise specified, all tests will be performed under the fol-

lowing conditions.

Temperature: Room ambient (+25 5C)

3-12.

The following definitions apply throughout this book:

a. Standard Logic Levels (SLL).

Logical 1 = +2.4 to +5.0 volts

Logical O = O to +O.6 volts

Pulse Width.

Pulse width is time measured between the 50% points of the

waveshape.

c. Pulse Repetition Interval (PRI). PRI is the time between consecutive

pulses, usually given microseconds. PRI is measured from a point

on one pulse to the corresponding point on the next pulse.

Continuity.

O to 3 ohms.

TEST EQUIPMENT USE

3-13.

a. Oscilloscope. Either one of the dual channel vertical inputs shall be

used. Triggering shall be as specified in the test instructions.

Normal inputs/outputs implied unless otherwise

b. Other Test Equipment.
