    The Tektronix Type 516 Oscilloscope is a dual-trace general purpose laboratory oscilloscope with a bandpass of dc to 15 megahertz. Dual-trace operation is provided by two identical vertical input channels; signals may be applied to either or both input channels at the same time. Switching between the two channels takes place at the end of each sweep of the beam or at a free-running rate of approximately 150 kHz. Either channel may be used seperately 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).
  • Risetime...23 nanoseconds or less.
  • Sensitivity...0.05 volts/div. to 20 volts/div. in 9 calibrated steps; accuracy with 3%. Continuously variable from 0.05 voly/div. to at least 50 volts/div., uncalibrated.
  • Input Impedance...1 megaohm paralleled by 20 picoforads.
  • Operating Modes...Channel A only, Channel B only, electronic switching at approximately 150 kHz (chopped), or electronic switching on alternate sweeps.
  • Maximum Voltage Input...600 volts, combined dc and ac voltage.

    -Triggering-
  • Type...Amplitude-level selection with preset or manual stability control.
  • Modes...Automatic, ac-coupled, dc-coupled, and high-frequency synchronized.
  • Source...Internal from vertical signal, external from triggering siganl, or line frequency.
  • Slope...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 response is 3 dB down to approximately 16 Hz.
    AUTO: 5 mm of display from DC to 1 kHz increasing to 2 cm at 2 MHz.
    AC LF REJECT: Attenuates frequencies 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 at 2 MHz. Low frequency response is 3 dB down at approximately 16 Hz.
    AUTO: 1 V from 50 Hz to 1 kHz increasing to 3 V at 2 MHz.
    DC: 0.5 V from DC to 1 kHz increasing to 1.5 V at 2 MHz.
    AC LF REJECT: Attenuates frequencies below 16 kHz.
    HF SYNC: 2 V at 20 MHz.
    Line-AC LF REJECT: Attenuates frequencies between 16 kHz.

    -Sweep-
  • Type...Miller Integrator.
  • Sweep Rates...0.2 sec/div. to 2 sec/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. ro 6 sec/div., uncalibrated.
  • Magnifier...Expands center portion of sweep 5 times. Extends fastest sweep rate to 0.04/sec div; accuracy within 5%

    -External Horizontal Input-
  • Bandpass...DC to 500 kHz (response not more than 3 dB down within these limits).
  • Deflector Factor...1.5 volts/div.

    -Amplitude Calibrator-
  • Waveform...Square-waves at approx. 1,000 cycles.
  • Amplitude...0.05 volt to 100 volts, peak-to-peak, in eleven fixed steps; accuracy within 3% of indicated amplitude.

    -Output Waveforms Available-
  • Positive gate, coincident with sweep, at least 20 volts peak-to-peak.

    -Cathode-Ray Tube-
  • Type...T55P31
  • P1, P2, P7 and P11 phosphors optional; other phosphors furnished by special order.
  • Accelerating Potential...4,000 volts.
  • Unblanking...Cutoff type, dc-coupled.
  • Z-Axis Modulation...External terminal permits RC coupling to crt cathode.
  • Deflection Factors at plates.
  • Vertical - 6 to 7 1/2 volts per centimenter.
  • Horizontal - 19 to 23 volts per centimeter.
