slope of the input voltage. If V
T
is kept the same but triggering were set to occur on
the negative slope of the input signal, at what points of the input signal in Fig. 3 might
triggering occur? How about a negative V
T
and positive slope? A negative V
T
and a
negative slope?
Fig. 3 shows plots of three ramp or sweep voltages. A given ramp voltage, no matter
which of the three plots it is associated with, corresponds to the same horizontal position
of the beam on the screen.

3 BK Controls for Single Trace Use
This section describes the controls (knobs and switches) and connectors (jacks) of the BK
scope for single trace use. In what follows, we will use controls to mean knobs, switches,
buttons, connectors, etc. There are a lot of controls, and unless you have a physical picture
of what the controls do you will not be able to use the scope in a reasonable sort of way.
Review the previous section and Fig. 4 as necessary.
Fig. 4 is a picture of the front panel of the BK scope. The controls are numbered. The
paragraphs that follow shortly are numbered according to the control being described.
At the left in Fig. 4 is the screen where the trace appear. On the right are the controls.
The controls are grouped in “boxes” according to function. All the boxes are named in
Fig. 4. The boxes are listed below along with the general function of the controls in each
