4 On the 5071A, set output ports 1 and 2 to 5 MHz using the front
panel controls.
5 Repeat step 3.
6 Connect 5071A Port 2 to the HP/Agilent 3585B Spectrum
Analyzer and repeat steps 2 through 5 to test Port 2.
7 Record the actual reading in the appropriate place in the
Performance Test Record.
B. Non-Harmonic (Spurious) Signal Check for the 5 and 10 MHz Outputs
Non-harmonically related (spurious) signals on the 5 and 10 MHz outputs
must be more than 80 dBc below the output signal levels. To perform this
test, a spectrum analyzer is tuned to the 5 or 10 MHz signal and an amplitude
reference is established. The output frequency spectrum is then examined at
1 MHz on either side of the center frequency to determine the fundamental-
to-sideband amplitude relationship for any signals occurring within this range.
