clock inside the signal generator must have the same base frequency reference as the clock used by
the device under test.
PSG Frequency Reference Connections
When a frequency reference is connected to the PSG, 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.
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 "24. BASEBAND GEN CLK IN" on
page 30. For information on the associated softkeys and fields for entering the frequency of the
applied clock signal or frequency reference, refer to the Agilent PSG Signal Generators Key
Reference.
