5. Set the generat
or to provide the signal to channel 1
6. Measure the Channel 1 crosstalk at 100 MHz as follows:
a. Set the center frequency to 100 MHz as follows: Push the front-panel
Freq/Span button. Push the side-bezel Center Frequency button. Set
the center f
requency to 100 MHz.
b. Use a marker to measure the amplitude of any of the Channel 1 signal that
appears in t
he RF display. See the following figure.
c. Record the amplitude of the C hannel 1 signal in the test record. Make sure
that it is within the specified limit.
7. Repeat step 6, changing the generator signal frequency and the oscilloscope
Center Frequency settings as indicated in the test record. Check all listed
frequencies and rec ord the results in the test record.
8. Repeat steps 5 through 7 until you have checked the crosstalk of all four
analog channels.
