  • Notes
  • The Type 3A6 Dual-Trace Amplifier plug-in unit contains two identical amplifier channels. Either channel can be used independently for a single-trace display, or the two channels can be electronically switched for a dual-trace display. Also, the two channels can be added algebraically and the resultant waveform displayed on the indicator unit crt.

    Cannot be used with a Type 560. Also, when used with a Type 2B67 or 3B2 time-base plug-in unit or with a Type 565 or RM565, it may not be possible to view the entire leading edge of the triggering waveform due to the delay of these time-base circuits.

    Frequency Response
    Dc to 10 mc (not more than 3 db down at 10 mc) with a corresponding risetime of typically 35 nanoseconds.

    Deflection Factors
    Ten calibrated steps for each channel; .01, .02, .05, .1, .2, .5, 1, 2, 5 and 10 volts/division. Variable control in each channel permits continuous, uncalibrated adjustment from 0.01 to about 25 volts/division in conjunction with the step switch.

    Within ±3% of indicated deflection with VARIABLE in the CALIB position.

    Input Impedance
    1 megohm ±1%, paralled by about 47 pf.

    Input Coupling
    Ac or dc coupled, selected by front-panel switch. In the  AC position low-frequency response is limited to about 2 cps (0.2 cps with 10 X passive probe).

    Maximum Input Voltage
    600 volts combined dc and peak ac; 600 volts peak-topeak ac.

    Polarity Inversion
    Polarity of Channel 1 can be changed to provide 180° inversion. No polarity inversion of Channel 2.

    Operating Modes
    Channel 1 only. Channel 2 only. Alternate between channels. Chopped between channels at approximately 150 kc rate. Added Algebraically.

    Channel Isolation
    50,000:1 or greater at 100 kc.

    Internal triggering signals for time base are provided from both channels or from Channel 1 only, determined by front-panel switch.

    Construction: Aluminum alloy chassis and panel.
