A block diagram of the Type 516 Oscilloscope is shown
in Fig. 4-1. In general, operation of the oscilloscope is as
follows:
The signal or signals to be displayed are applied to the
Vertical Amplifier through the A and/or B input connectors.
The Vertical Amplifier amplifies the signals and applies them
through the Delay Line to the vertical deflection plates of
the cathode-ray tube. A sample of the signal is taken out at
the Vertical Amplifier and applied to the Time-Base Trigger.
The Time-Base Trigger generates a trigger pulse which bears
a selected fixed time relationship to the incoming signal. This
trigger pulse triggers the Time-Base Generator which gen­
erates a linear sawtooth waveform. The sawtooth waveform
is applied through the Horizontal Amplifier to deflect the crt
beam horizontally at a selected fixed rate. Provisions are
also made for generating trigger pulses which bear a selected
fixed time relationship to some external signal or to the ac
line waveform. If desired, the Time-Base Generator may be
disabled and an external signal applied directly to the Hori­
zontal Amplifier. The Amplitude Calibrator provides an am­
plitude-calibrated square wave for use in calibrating the
gain of the Vertical Amplifier and adjusting the compensa-
