4 - 16 HOW TO USE THE INSTRUMENT
VERTICAL AMPLITUDE
- Press the upper key of the AMPL keys
Pressing the upper key increases the amplitude of the displayed
waveform. As the amplitude of the displayed waveform changes, the
screen readout of the input sensitivity changes as well.
If you adjust the displayed amplitude to 6 divisions, you will notice that
the readout in the lower left hand corner of the screen reads 100 mV/div.
The amplitude of the signal is then: 100 mV/div times 6 div = 600 mV.
Try other sensitivity settings as follows :
- Use the AMPL keys to step through the attenuator range.
Observe that the sensitivity readout changes in steps following a 1, 2, 5
sequence. The AMPL keys allow you to step up and down through the
sensitivities from 5 V/div to 2 mV/div and vice-versa. This sequence enables a
quick selection between the oscilloscope’s sensitivity positions and are such that
almost every input signal can be made visible with sufficient amplitude.
