frequencies below 16 kHz. HF SYNC: 2 V at 20 MHz.
Line-AC LF REJECT: Attenuates frequencies between 16
kHz.
The Tektronix Type 516 Oscilloscope is a dual-trace gen­
eral purpose laboratory oscilloscope w ith a bandpass of
dc to 15 megahertz. Dual-trace operation is provided by
tw o identical vertical input channels; signals may be applied
to either o r both input channels at the same time. Switch­
ing between the two channels takes place at the end of each
sweep of the beam or at a free-running rate of approxi­
mately 150 kHz. Either channel may be used separately to
provide single-trace operation when desired.
Vertical Deflection System, Both Channels
Bandpass . . . DC to 15 MHz (response not more than 3 dB
down within these limits).
Sweep
T y p e .. .M iller Integrator.
Sweep Rates. . .0.2 jusec/div. to 2sec/div. in 22 calibrated
steps. Accuracy typically within 1% of full scale; in all
cases, within 3% of full scale.
Continuously variable sweep rates are available from 0.2
/.<sec/div. to 6 sec/div., uncalibrated.
M agnifier. ., Expands center portion of sweep 5 times. Ex­
tends fastest sweep rate to 0.04 /^sec/div; accuracy within
5%.
External Horizontal Input
Risetime. . . 23 nanoseconds or less.
Sensitivity. .0.05 v o lt/d iv . to 20 volts/div. in 9 calibrated
steps; accuracy with 3% . Continuously variable from
0.05 v o lt/d iv . to at least 50 volts/div., uncalibrated.
Bandpass . . . DC to 500 kHz (response not more than 3 dB
down within these limits).
Deflection Factor. . .1.5 volts/div.
Input Im pedance... 1 megohm paralleled by 20 picofarads.
O perating Modes . . . Channel A only, Channel B only,
electronic switching at approximately 150 kHz (chopped),
or electronic switching on alternate sweeps.
Maximum Voltage I n p u t . . . 600 volts, combined dc- and ac-
voltage.
Triggering
Type. . .Am plitude-level selection with preset or manual sta­
b ility control.
M odes. . . Automatic, ac-coupled, dc-coupled, and high-
frequency synchronized.
Source. .. Internal from vertical signal, external from trigger­
ing signal, or line frequency.
S lo p e ... Plus (rising slope of triggering waveform), or minus
(falling slope of triggering waveform).
Signal Requirements . . . Internal-AC: 2 mm of display at
1 kHz increasing to 5 mm at 2 MHz. Low frequency re­
sponse is 3 d B down at approximately 16 Hz. AUTO: 5
mm of display from 50 Hz to 1 kHz increasing to 1 cm at
2 MHz. DC: 5 mm o f display from DC to 1 kHz increas­
ing to 2 cm at 2 MHz. AC LF REJECT: Attenuates fre­
quencies below 16 kHz. HF SYNC: 2 cm of display at
20 MHz. External-AC: 0.5 V at 1 kHz increasing to 1.5 V
a t 2 MHz. Low frequency response is 3 dB down at ap­
proxim ately 16 Hz. AUTO: 1 V from 50 Hz to 1 kHz in­
creasing to 3 V at 2 MHz. DC: 0.5 V from DC to 1 kHz
