Instructions for a B&K Precision Oscilloscope

B&K's oscilloscope line follows standard conventions for electronic equipment. As with oscilloscopes from other manufacturers, a B&K has a display screen, controls for horizontal sweep and triggering and two or more independent input channels. Each channel lets you adjust for sensitivity to a wide range of electronic signal voltages. As of 2012, B&K offers two basic types of oscilloscope: analog and digital. Though digital models have extra features such as on-screen menus and signal analysis, the basic controls on both types work in similar ways.

Things You'll Need

BNC instrument cable
Function generator
B&K oscilloscope

Instructions

- 1
  Plug one end of the BNC cable into the output connector on the function generator. To do this, push the BNC female on the cable onto the male connector on the function generator and twist clockwise 90 degrees until it locks into place. In the same fashion, connect the other end of the cable to the B&K oscilloscope̵7;s channel one input.
- 2
  Turn the function generator and oscilloscope on. The function generator powers up immediately. If the oscilloscope has a traditional CRT display, you will see a trace on the display in a few seconds. An oscilloscope with an LCD displays a trace without warm-up time.
- 3
  Adjust the ̶0;Intensity̶1; and ̶0;Focus̶1; knobs on the oscilloscope until you see a clearly-defined trace on the display.
- 4
  Set the function generator̵7;s frequency to 1,000 Hz. Set its output amplitude to 50 percent of maximum. Select a sine waveform.
- 5
  Set the oscilloscope̵7;s horizontal sweep rate to 1 millisecond per division. Set the channel one input coupling to AC. Adjust the channel one input sensitivity to one volt per division. You should see several cycles of a sine wave on the display; the sine wave̵7;s height should be a few divisions of the display̵7;s grid for both positive and negative parts of the waveform.
- 6
  Set the oscilloscope̵7;s trigger selection switch to channel one and adjust the ̶0;Trig Level̶1; knob until the sine wave appears to ̶0;lock̶1; in place on the display. If the wave drifts to the right or left, the oscilloscope̵7;s horizontal sweep is not in sync with the function generator.
- 7
  Increase and decrease the function generator̵7;s frequency knob and observe that you see more and fewer cycles of the sine wave on the oscilloscope display. The sine wave remains in sync with the function generator.
