    The Type 3A6 Amplifier is a general-purpose, dual-trace plug-in unit designed for use in the Types 561B, 564B and 565 Oscilloscopes. It can also be used in the Type 568 Oscilloscope when digital readout is not required.

    The Type 3A6 features two separate channels with identical characteristics. It can be operated in any one of five modes for a variety of single and dual-trace displays. Two Type 3A6's can be used for X-Y curve tracing, but without synchronized switching or channel pairing.

    BANDWIDTH
    DC to 10 Hz at 3-dB down. AC-coupled low-frequency response is 2 Hz, 0.2Hz with 10X probe.

    RISETIME
    Approximately 35 ns.

    DEFLECTION FACTOR
    10 mV/div to 10 V/div in 10 calibrated steps, 1-2-5 sequence; accurate within 3%. Uncalibrated, continuously variable between steps and to approx. 25 V/div.

    INPUT RC
    1 megohm paralleled by approx. 47 pf.

    MAXIMUM INPUT VOLTAGE
    600 V combined DC + peak AC.

    OPERATING MODES
    Channel 1 only (polarity of Channel 1 can be changed to provide 180° inversion);
    Channel 2 only;
    Alternate -- Channel 1 and 2 switched electronically on alternate sweeps;
    Chopped -- successive 4 μs (approx) segments of each channel are displayed at an approx. 135-kHz rate per channel (chopped transient blanking is provided);
    Added -- outputs of CHannel 1 and 2 added algebraically.

    INTERNAL TRIGGER SIGNAL
    Selectable from the output of Channel 1 only or from the combined output of the unit. Triggering from Channel 1 only permits viewing the true relationship between two signals when operating the unit in either alternate or chopped mode.

    SIGNAL DELAY
    Permits viewing of leading edge of fast-rise waveforms. (The Type 3A6 can be used with a Type 2B67 or Type 3B2 Time-Base Unit, but it will not usually be possible to view the entire leading edge of the triggering waveform. Same applies when the unit is used with Types 565 and RM565 Oscilloscopes)
