    Used with Type 547, the alternate switching circuit can be slaved to the display switching circuit in the oscilloscope, thus locking Channel 1 to Time Base A and Channel 2 to Time Base B. This approaches the equivalent of a Dual-Beam Oscilloscope.
    Used in the 1960's.
    SPECIFICATIONS

    The Type H Plug-In Unit is a dc-coupled, high-gain, wide-band, calibrated preamplifier, designed for use with Tektronix 530-, 540-, and 550-Series oscilloscopes.

    Deflection Factor

    0.005 v/cm to 20 v/cm in twelve fixed calibrated steps.
    0.005 v/cm to 50 v/cm, continuously variable

    Maximum Allowable Combined DC and Peak AC

    600 V

    Input Impedance

    Input of plug-in unit : 1 megohm shunted by 47 pf
    Input of Type P6000 Probe: 10 megohm shunted by 11.5 pf
    Input of Type P6017 Probe: 10 megohm shunted by 14 pf
    Front-Panel Controls

    INPUT SELECTOR SWITCH - a 4-position switch to select AC or DC coupling from either input connector.

    VERTICAL POSITION CONTROL - used to position the trace vertically on the face of the oscilloscope screen.

    VOLTS/CM SWITCH - provides fixed calibrated vertical-deflection factors when the associated VARIABLE control is set to CALIBRATED. The VARIABLE control provides continuously variable (uncalibrated) vertical deflection factors between those provided on the VOLTS/CM switch.
