3) QUICK PERFORMANCE CHECK:

Connect a 10X attenuating probe to Channel 1. Change three (3) settings as follows:

a) Vertical Section: Channel 1, change Probe Factor (a softkey that says Probe) to

10:1. You can do this by pressing the oval button labeled “1”, and then turning the

control called the “Entry Knob”, located just to the right of the CRT, below the

horizontal section, with an illuminated curved arrow above it.

b) Vertical Section: Channel 1, change to 500 mV/div scale. You can do this by

pressing the oval button labeled “1”, and then turning the control right above the oval

button and observing the vertical scale (at the top left side of the CRT screen).

c) Horizontal Section: change time/division to 5 ms/div, using the larger control.

Now, touch the probe tip with your

finger. If you see a few cycles of a

sine wave with several cm of vertical

deflection (like the display to the

right), both your oscilloscope and

your probe are functioning. Note:

you may need to use 200 mV/div or

1V/div, depending on where you are.

It turns out the “signal” you are

observing is 60 Hz. power line noise,

and your finger (which is most likely

connected to your body, a crude

antenna) is providing a very

convenient “test” signal picked up from the power wiring in the building.

4) Connect the Channel 1probe tip to the Probe Comp output (near the right edge of the front

panel). The display should look like the display below: not very satisfactory, but you can see

there’s some kind of waveform.
