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)
