10 MHz REF OUT ANALOG MODULATION IN
Connectors
10 MHz REF OUT
This connector furnishes a 10 MHz reference for external instruments.
Operating Considerations
NOTE The reference output frequency is always 10 MHz,
independent of the selected input reference frequency.
16 × CHIP CLOCK 19.6608 MHz OUT
This output provides a 19.6608 MHz (16 times the CDMA chip rate)
square wave with a 50% duty cycle. This signal comes from the CDMA
frame clocks.
ANALOG MODULATION IN
This connector provides an external modulation connection to the RF
generator.
Operating Considerations
The Mod In To field of the RF GENERATOR screen sets the type of
modulation (AM or FM).
The FM Coupling field on the RF GENERATOR screen selects ac or dc
coupling of this signal for FM operation.
