2.2 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 Connector
Use this connector to transfer the main output signal from the function generator. One connector is
available for each channel.
Trig In Connector
Use this connector to apply an external trigger or gate signal, depending on the waveform generator
setting, to the generator. When the built-in frequency counter is enabled, this connector becomes an
input for the counter. The connector is common to both channels acting as the MODE selected for
each channel.
Sync Out Connector
Use this connector to output a positive TTL sync pulse generated at each waveform cycle. One
connector is available for each channel.
Modulation In Connector
5V p-p signal for 100% modulation, 10Kohms input impedance with DC - >20 KHz bandwidth. The
connector is common to both channels acting as the MODULATION function selected for each
channel.
2.3 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.
