Troubleshooting
— If the signal generator does not meet the listed power level in Table 1-2,
proceed to “Troubleshooting the RF Path” on page 48.
The ALC loop circuitry is part of the A20 Output Leveling Module. It is likely an
unleveled or under power condition is the result of a problem with the A20
Output Leveling Module.
— For an N5193A signal generator, replace the A20 Output Leveling Module.
