NOTE. If the DC voltage source you are using has an output head, use a
female-to-female BNC adapter and a short BNC cable to make the connection to
the first BNC tee.
When you are given the instruction to apply a 0 V DC signal, turn off or ground
the output of the DC voltage source to be sure that no DC voltage is present.
Later in the procedure, a leveled sine wave needs to be applied to each channel,
one channel at a time. A typical on-screen instruction might read:
Apply 400.00 mV PkĆPk sine wave signal to channel 1 only.
When you see an instruction similar to this, connect the leveled sine wave
generator to the specified channel and then set the amplitude and frequency to
the specified values.

NOTE. If the leveled sine wave generator you are using has an output head,
connect the head directly to the channel input.
Make sure that the AC generator output is set for a 50-ohm load for all
AC-source steps.
