ELECTRONIC PRINCIPLES - OD1647 - LESSON 1/TASK 3
(d) Add. Adds, algebraically, signals from the left and
right vertical plugin channels. This is useful. for removing
undesired components common to both signals (common mode
rejection) or to add signal component to one channel to offset a
like component in the, other channel (dc offset).
(e) Right. Selects the signal applied to the right vertical
plugin channel for crt display.
(2) Time Base Generator Modes.
(a) Main Sweep. Provides a means of displaying the signal
in direct time relationship using any main frame mode discussed
in paragraphs 2b(1)(a) through 2b(1)(e) above.
(b) Delayed Sweep. Provides a means of displaying the
signal in delayed time relationship in any main frame mode
listed in paragraphs 2b(1)(a) through 2b(1)(e). Displayed sweep
is delayed by the main sweep and DELAY TIME MULT control
settings.
(c) Single Sweep. Allows the time base generators to run
through one sweep cycle only. Another sweep cannot be triggered
until the RESET switch is pressed. Can be used with any main
frame mode listed in paragraphs 2b(1)(a) through 2b(1)(e).
(d) Amplifier. Provides a means of applying the external
signal to the horizontal amplifier. Can be used with xy
measurements, or for applying an external sweep signal.
c. Controls and Indicators. All controls, indicators,
protective devices, and connectors for both the front and rear
panels of the oscilloscope are described (in the following
paragraphs) as to section of the scope and the function
performed.
(1) Front Panel (figure 97 on the following page).
(a) INTENSITY Control. Controls the brightness of the
display. inoperative when the horizontal plugin compartment is
empty.
(b) FOCUS Potentiometer. Controls the definition of the
display.
