ESG Frequency Reference Connections
When a frequency reference is connected to the signal generator, it is applied to one of two rear panel
connectors:
• 10 MHz IN
• BASEBAND GEN REF IN
The BASEBAND GEN REF IN connector will accept a frequency reference in the range of 1 to 100 MHz. If
the external or device under test clock source cannot provide or accept a frequency reference, that clock
signal can be applied to this connector and used as the frequency reference (as long as the frequencies are
within the specified range).
Whenever an external clock signal or frequency reference is connected to the BASEBAND GEN REF IN
connector, its frequency needs to be entered into the current signal generator modulation format. For
information on the BASEBAND GEN REF IN connector refer to Chapter 2, “E4438C Vector Signal
Generator Overview,” on page 19. For information on the associated softkeys and fields for entering the
frequency of the applied clock signal or frequency reference, refer to the Key and Data Field Reference.
