Introduction
This section of the manual is divided into three parts.
The first part, Preliminary Instructions, is a step-by-step
procedure designed to acquaint a “ first-time” operator of a
Tektronix oscilloscope with the basic operation of the Type
516. The second part, Operating Information, which starts
on page 3-5, covers all phases of the operation of the
Type 516 Oscilloscope in detail. The third part, Applica­
tions, which starts on page 3-8, describes techniques which
can be used for certain basic applications of the Type 516
Oscilloscope.
Preliminary Instructions
The front panel of the Type 516 Oscilloscope is shown in
Fig. 3-1. Functions of all front panels controls, indicators,
and connectors are described in Table 3-1.
TABLE 3-1
TRIGGER Selects source of triggering signal and
SELECTOR slope on which triggering occurs.
(black knob)
TIME/DIV.
VARIABLE
TIME/DIV.
(red knob)
Selects the desired horizontal sweep rate
from 22 calibrated steps.
Provides a continuous range of sweep rates
between the fixed steps selected by the
TIME/DIV. control. (The sweep rates are
calibrated only when the VARIABLE con­
trol is in the CALIBRATED position.)
UNCALIBRATED Lights when VARIABLE TIME/DIV. control
lamp is not in the CALIBRATED position.
TRIGGER Selects triggering mode.
SELECTOR
(red knob)
TRIGGER INPUT Coaxial connector for application of ex­
ternal triggering signal when black TRIG­
GER SELECTOR control is in the EXT.
position.
PRESET STABILITY Sets triggering stability level when red
TRIGGER SELECTOR control is in the
AUTO, position, or when STABILITY con­
trol is in the PRESET position.
TRIGGERING Selects the voltage point on the triggering
LEVEL waveform at which the horizontal sweep is
triggered.
STABILITY OR Sets Time-Base Generator for triggered or
HORIZ.-INPUT free-running operation. Also serves as
ATTEN. (red knob) attenuation control for signals applied
through EXT. HORIZ. INPUT when HORIZ.
DISPLAY switch is in the EXT. position.
HORIZ. DISPLAY Sets horizontal sweep for normal or magni­
fied (X5) presentation. Also provides for
application of external signal to Horizon­
tal Amplifier.
VOLTS/DIV.
VARIABLE
VOLTS/DIV.
(red knob)
UNCALIBRATED
lamp
SHUNT and
SERIES
adjustments
POLARITY
POSITION
(red knob)
DC. BAL.
A VERTICAL
Selects the sensitivity of the A VERTICAL
Channel from nine calibrated steps.
Provides a continuous range of sensitivity
values between the fixed calibrated steps
selected
by the VOLTS/DIV. control.
(Sensitivity is calibrated only when the
VARIABLE control is in the CALIBRATED
position.)
Lights when VARIABLE VOLTS/DIV. con­
trol is not in the CALIBRATED position.
Compensation adjustments for attenuator.
(See Calibration Section.)
Selects ac or dc coupling of signal applied
to A VERTICAL input connector, and nor­
mal or inverted presentation on the screen.
Controls vertical positioning of A VERTI­
CAL Channel signal on the crt screen.
Provides for vertical stability of no-signal
trace for all positions of the A VERTICAL
VOLTS/DIV. control.
