Advanced mode
Use the same equipment setup as in the Basic mode test. Offset and Vocm are
only available in DC direct and DC ampli
fi
ed when in Advanced mode.
1.
Close Basic mode and launch Advanced mode in the generator.
2.
Check that the generator is still connected to the DMM as shown in the
following
fi
gure and that the 50
Ω
terminator is still connected to the
generator’s side output connector.
