Rf Generator Fm Accuracy; Performance Test 2 - Agilent Technologies E8285A Manual

RF Generator FM Accuracy

Performance Test 2

The purpose of this test is to verify that the Test Set meets the specification limits
in PTR (Performance Test Record)
Record" on page
by the measuring receiver. The Test Set's internal audio generator provides the
modulation source.
NOTE Two setups are shown below. The first setup can measure signals to 1 GHz. Since
the FM generator in the Test Set translates FM in the lower band directly into the
1.7 to 2 GHz range, testing to 1 GHz is adequate when verifying a repair. The
second setup has a microwave converter which covers the full measurement range
of FM signals to 2 GHz.
