4A-10.
RF leakage is verified by measuring the induced signal in a two-turn loop with the
Measuring Receiver.
REQUIREMENTS
The output signal leakage must induce less than I JJ.V into a l-inch diameter two-turn
loop, I inch away from any surface of the generator as measured into a 50-ohm receiver.

A screen room may be required depending on the RF environment.
REMARKS
This test is an alternative to the Output Leakage test.
Failing this test indicates a problem feed-through filter or improper mechanical
assembly, i.e., loose screws, and/ or damaged or misplaced gaskets.
The Measuring Receiver is used to measure the U UT leakage relative to a I
established at each frequency.
PROCEDURE
a. Connect the UUT 1 0 MHz OUT to the 10-MHz timebase input of the
b. Set the U UT REF !NT j EXT switch to INT.
c. Program the UUT to the Instrument Preset State, [RCL] [98).
d. Program the UUT to - 107 dBm.
