Functional Tests
Relative Frequency Range and Accuracy Check
10.Repeat step step 8 and step step 9 for all of the frequencies in the table
that are within the frequency range of your signal generator.
Troubleshooting Problems with the Frequency Accuracy Check
— Verify the cables are connected correctly.
— If you are using a frequency counter, verify that you are using the correct
channel for the frequencies you are measuring.
For frequencies <200 MHz, use Channel 3 on the frequency counter
(press Freq Ratio
until CH3: displays).
