GENERAL
FEATURES
Top of the line in Leader’s instruments, Model LS
8106A offers speed and operating shortcuts found in
very few modern scopes. Examples include Auto
Setup in which a single touch automatically sets both V
sensitivity and timebase for instant, optimum waveform display. Another great convenience is a continuous on-screen readout of the operator’s choice of frequency or period and V p-p or DC level for signals
handled in CH1. Solid state switching in the vertical
attenuators also eliminates switching noise and ensures long-term reliability. Two X10 probes (LP-103C)
are supplied as standard equipment.
