1. Press the key that leads to the item to change.
2. Move cursor using cursor keys to the appropriate position in
the numeric field (if applicable).
3. Use the rotary input or the numerical keyboard to change the
value of the displayed item. Changes take effect immediately.
3.4 Connectors
The function generator has two BNC connectors on the front
panel where you can connect coaxial cables. These coaxial
cables serve as carrier lines for output signals delivered from
the function generator.
Output
Use this connector to transfer the main output signal from the
function generator.
Sync Out
Use this connector to output a positive TTL sync pulse
generated at each waveform cycle.
3.5 Output Connections
The waveform generator output circuits operate as a 50
Ω voltage source working into a 50 Ω load. At higher
frequencies, non terminated or improperly terminated
output causes aberrations on the output waveform. In
addition, loads less than 50
Ω reduce the waveform
amplitude, while loads more than 50
Ω increase
waveform amplitude.
Excessive distortion or aberrations caused by improper
termination are less noticeable at lower frequencies,
