15. Change the following 370B settings:
16. Note that the collector supply is in the DC mode and that the steps are
displayed as a diagonal array of dots on the CRT screen. Readjustment of the
display intensity may be necessary.
17. Press the Measurement SWEEP button. The Collector Supply voltage is
decreased from the previously-set value to 0%, resulting in series of dots
representing the collector current vs. collector-emitter voltage characteristic.
18. Set the Step Generator PULSE control to OFF and the control counterclock-
wise to 100 mV BASE/EMITTER. Note the display of the collector current
vs base-emitter voltage for ten different values of base current (see Figure
3–9).
