●
Reference Output = "10 MHz, 100 MHz" or "Input Signal (loop through)"
(earlier RF hardware versions: 5 MHz, 10 MHz, 13 MHz)
●
Set the synchronization bandwidth according to the requirements of the applica-
tion.

= 10 MHz, 100 MHz, 1 MHz to 100 MHz external reference frequency
REF IN, REF OUT = Connectors
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)

MHz (derived from an external reference frequency)
