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
