NOTE
only, you can specify alternating current (ac) or direct current (dc)
coupling at the analyzer input. Selecting ac coupling blocks any dc
voltage at the analyzer input, but also decreases the frequency range of
the analyzer. Make sure the analyzer is dc coupled when measuring
below 100 kHz for Agilent E4402B, E4404B, and E4405B and below
10 MHz for Agilent E4407B. (See
