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 E7403A and E7404A and below 10 MHz for
Agilent E7405A. (See
