3.4 I/O Connection
■ Waveform Output (FUNCTION OUT)
The output impedance of FUNCTION OUT connector is 50 Ω. (Open when the output is off.)
To maintain the flatness and waveform quality of the amplitude frequency characteristics, use a
coaxial cable with a characteristic impedance of 50 Ω and terminate the input connector of the
equipment to connect with 50 Ω.
If the frequency is low, it does not matter even if it is not terminated with 50 Ω.
Since the output impedance is 50 Ω, the output voltage that is actually output varies depending on
the load impedance.
■ Synchronous Output (SYNC OUT)
The output impedance of SYNC O UT connector is 50 Ω. (High impedance when the output is off.)
To maintain the waveform quality, use a coaxial cable with a characteristic impedance of 50 Ω and
terminate the input connector of the equipment to connect with 50 Ω.
