For the 4286A, only Ls-Rs can be set for the
equivalent circuit; whereas, for the 4287A,
either Ls-Q or Cp-D can also be selected for
√
√
the equivalent circuit.
The 4287A is not provided with a specific
√
√
key associated with this function; the setting
is run at the same time the data is input.
√
For the 4286A, only one value can be set for
√
√
all frequencies; for the 4287A, each list
sweep frequency can be set.

√
√
√
√
√
√
For the 4287A, LOAD compensation is not
√
available; calibration should be used for this
purpose.
