a.
be repeated cycle after cycle. Each waveform can be modulated with either external or internal signals. Both
internal and external modulation can be from amplitude, frequency, or phase sources. Only one of the many
outputs possible in this mode will be produced in the following steps.
(1)
Set POWER OFF/ON switch (1) to OFF. (Refer to figure 2-1)
(2)
Connect a 50 ohm BNC to BNC coaxial cable from the FUNCTION OUT (50 Ω) connector (14).
(3)
Terminate remaining end with a 50 ohm feedthrough load.
(4)
Connect terminated end of BNC cable to test equipment.
Set POWER OFF/ON switch (1) to ON.
(5)
Set all controls to positions given in table 2-4. Use figure 2-1 to locate the desired controls and/or
