Frequency Response Bandwidth is measured with a leveled, low
distortion,
so-n source, sine-wave generator,
terminated
in
SO
n.
The reference signal
amplitude is set at the lesser of 6 divisions
or
the maximum leveled amplitude.
Bandwidth with probe is checked using a
probe-tip-to-GR
(017

termination
adapter.
Bandwidth with external termination
is
checked
using a BNC
so-n feed through terminator
(011-0049-01
).
