box. After the name of the box, in parentheses, are the numbers of the controls that appear
in that box. As you read, identify the boxes in Fig. 4. The box names are hard to read; the
numbers are not.
“FUNCTION” BOXES OF BK SCOPE
(Numbers in parentheses refer to the controls in the box)
• POWER Button (2) turns the scope on and off.
• VERTICAL(3-4)- This box is really divided into two boxes. The scope has two possible
input voltages. The controls for the gain which are in this box, the gain for channel 1
is on the left and for channel 2 on the right. In this box are also controls for moving
the traces up and down. (11 and 12) There are also two connectors for possible input
voltages. Below the box (9 and 14)
• HORIZONTAL(time base)(5)- Controls the rate at which the horizontal deflection volt-
age is changed. This also affects the apperance of the signal.
• TRIGGER(6)- Determines the level at which the scope senses the signal. Rotating knob
enables you to select V
T
. Knob (6) moves the trace left and right.
Below is a number list that tells you the controls at certain values or positions. Be sure
to do this so that when you turn the scope on you can see a trace. With a strange scope
just finding a trace can be difficult!
Note: The controls for the gain (Voltage / Division) determines the visual appereance of
the signal on the screen.
1. Channel 1 and Run/Stop will be lit when the scope is on.
2. POWER pushbutton. Turns scope on and off. Leave scope off (button out).
6. Trigger LEVEL/KNOB. Adjusts the trigger level voltage, V
T
.
7. USB port to record and transfer wave forms. Not used in this lab.
8. Calibrate. Provides a 2 V p-p 1 kH calibration square wave. Not used in this lab.
9. CH1 INPUT JACK. Connect the signal you wish to examine to this jack. The jack is a
female Baby Type N connector, or BNC connector.
10. CH1 VOLTS/DIV control. This is the vertical sensitivity control for channel 1 and
determines the amount of amplification applied to the input signal before the input signal
is connected to the vertical deflection plates. The setting of this knob gives the vertical
deflection of the trace for a particular input signal. For example, if this control is set at
50 mV, a 100 mV input signal will produce a 2 cm vertical deflection of the trace.
11. CH1 POSITION control. Moves the trace vertically.
12. CH2 POSITION control. Adjusts the vertical position of the channel 2 trace if there is
one. CH2 is not used in this lab.
