In

operation
via
the
IEEE 488
Interface,
hardware
switching
occurs
under
the control
of

Any
transfer
(up

the
undermentioned

must be
regarded as
a
frequency range change.

Measurements
at

can
often
be
susceptible
to
RFI
pickup.
Generally,
care
is
needed where
the
measurement

is
greater than

is
not
recommended
for
best
performance
in
calibrating
high bandwidth,
