You can forward reference frequency between 1 MHz and 100 MHz directly to the out-
put in the same way.
●
External f
Ref
= 1 MHz to 100 MHz
( 1 MHz to 100 MHz at connector Ref In and Ref Out )
●
Source = "External"
●
Variable Reference Frequency = "Variable"
●
External Reference Frequency = current external frequency
●
Reference Output = "Input Signal (loop through)" or specify the reference fre-
quency the synchronized instrument supports
●
Set the synchronization bandwidth according to the requirements of the applica-
tion.
Deriving 10 MHz from the external reference frequency
10 MHz reference frequency can be derived from the following external reference sig-
nals:
●
10 MHz from internal oscillator locked to external input
●
100 MHz and 1 GHz external reference signals
●
External reference signal between 1 MHz and 100 MHz
●
If the external reference signal is interfered (noisy)

7.10 Varying the RF signal in list or sweep mode
The operating modes "List" and "Sweep" allow you to generate an RF signal having
periodically varying frequencies or amplitudes.
