Quick Tips
The external reference Input and Output connectors are used for synchronizing multiple AFG3000 series instruments.
Refer to page 60 for synchronous operation.
The arbitrary/function generator can use the internal source or an external source as a reference signal. When the
internal reference is activated, a 10 MHz reference signal is output on the rear panel EXT REF OUT connector. This
output signal synchronizes other devices to the arbitrary/function generator.
When the external reference input is activated, the rear panel EXT REF INPUT connector is used as the input for an
external reference signal. The arbitrary/function generator is synchronized by this external reference signal.
The EXT REF OUTPUT connector is not provided with the AFG3021B and AFG3022B.
1. The external reference input (EXT REF
INPUT) and the external reference
output (EXT REF OUTPUT) connec-
tors are provided on the AFG3000
series rear panel.
2. The instrument can use the internal or
external signal as a reference signal.
To select a reference signal, push the
front-panel Utility button and then push
the System bezel button.
3. Push the Clock Ref bezel menu button
to toggle between Internal and
External.
