The BOS Series comprises
dual-channel oscilloscopes with
frequency bandwidths of
40 to 100 MHz at -3 dB, a maximum
sweep of 10 ns, a maximum
sensitivity of 1 mV/DIV, and
150 mm rectangular CRT with
internal graticule.

These oscilloscopes are rugged,
easy to operate, and highly reliable.
They are ideal for research,
production, and electronics
applications. The BOS converts a
high-input differential voltage
(≤1300 Vp) into a low voltage (≤6.5V).

Optional accessories include
differential voltage probes, which
provide a safe means of measuring
a floating potential.
