1. GENERAL INFORMATION
1-1. INTRODUCTION
The LBO-516, shown in Figure 1-1, is a 100 MHz oscilloscope
with all of the features normally found on a lab-grade scope: high-
fidelity pulse response, stable operation, dual timebase with
calibrated sweep delay, flexible triggering facilities, and a bright
CRT display with illuminated internal graticule. Moreover, it also has
a very unusual feature found on few scopes in any price class: it can
simultaneously display up to eight traces from three different input
signals! In addition to the two vertical-input channels and their differ-
ence signal, the signal used to externally trigger the main timebase
can also appear on the CRT display. The alternate sweep mode,
which allows the main and delayed timebases to simultaneously
sweep the CRT, effectively doubles this four-trace display to an
eight-trace display.
The comprehensive triggering facilities of the LBO-516 include
several features that ease the problem of triggering on complex
signals: a variety of frequency-selective coupling filters, a trigger
holdoff-control, and a trigger pickoff that alternates between the two
vertical channels.
