Additional Information for Troubleshooting the
ESG-AP and ESG-DP Series
Table 1-5 provides frequency-dependent settings for selected points in the RF signal flow of
the ESG-AP and ESG-DP Series Signal Generators. Notice that the settings are relative to
the RF output frequency. This information can improve your understanding of the signal
generator circuitry, especially when used with the RF block diagram.
NOTE The values for Table 1-5 assume FM modulation is turned off.
