Information
GENERAL
)
The 5228 Oscilloscope has a bandwidth up to 250 MHz, double timebase and
three separate vertical channels.
Channels A, B and C can be used separately or simultaneously in the "sweep
alternate" or "chopped" mode, and in the algebraic addition mode (A + B).
Channel B can be inverted.
The double timebase {Bl, B2) provides a choice of the following sweep modes
: Bl only, Bl + B2 delayed and extra-bright, B2 delayed only, Bl and B2 mixed,
and Bl and B2 alternated.
Triggering can be controlled internally from channel A, B or C, line source, or
an external signal. Triggering over 250 MHz is also possible.
Y mode, X mode and Bl and B2 trigger mode controls are incorporated in a
keyboard. LEDs come on to indicate selected functions. Utilization of this
keyboard is further improved by the inclusion of two preselected function
memories.
The Oscilloscope also has a digital display, used for measurement of DC
voltages applied to a "voltmeter" input, or for display of Adiv vertical offset
between the Bl and B2 sweeps ("sweep alternate" mode), or display of the At
time interval between any two points of a phenomenon observed on the
screen.
