The model LBO-308S is a high-quality dual-trace, 20-MHz
portable oscilloscope ideally suited for field service. It
is an extremely compact, lightweight, general-purpose
instrument, designed to provide accurate signal measurements
for either bench or field service. The highly sensitive
vertical amplifier provides calibrated deflection
sensitivity from 2 mV/div to 10 V/div. The time base
provides stable triggering over the full bandwidth of the
vertical amplifier as well as calibrated sweep speeds from
0.2 sec/div to 0.5 µsec/div. A times 5 magnifier extends the
maximum sweep speed to 0.1 µsec/div.
The instrument may be operated from either 117/234 volts AC,
11 to 30 volts DC, or from battery pack.
The model LBO-308 features a 3-inch rectangular 8 X 10
division CRT, mounted horizontally, with an internal
graticule which provides for accurate and sharp displays at
any viewing angle without parallax errors.
