What is the Answer?
- Well firstly what you see on your display will
vary depending on the setting of the Vertical Gain Control.
- Even so regardless of the setting of the Vertical Gain Control
you should find that the voltage across the 50 Ohm
resistor is about 3.3 volts.
- The diagram below shows what you should see if
the Vertical Gain
Control is set to 1volt per
- Why can't I see anything on the display?
Intensity not adjusted
- Vertical Gain
Control setting on too low a
value per division, which sends the trace off the
- Why is the display showing a reading of zero
- AC-GND-DC Selector
is set on the GND
- The Mode
Selector is on the Channel A
setting while the input signal is being applied
to Channel B or vice versa.
- The Vertical Gain
Control is on a high volt
per division setting. e.g 20V/div.
- Why is the reading on the display not equal to
Varaible Vertical Gain
Control is not in the calibrated position.
- The circuit being measured is not
e.g. Incorrect power source, wrong resistors etc.
