Vertical System
Introductory on how to set the vertical system of the handheld oscilloscope.
Enable the Channel
The T3DSOH1000/T3DSOH1000-ISO provides 2 analog input channels and each
channel shares the same vertical control system. Since the vertical system setting
methods of each channel is the same, this chapter uses CH1 as an example to introduce
the setting method of the vertical system.
Connect the signal to the CH1 channel connector; and then press the CH1 button in the
vertical control area (VERTICAL) on the front panel to enable CH1.
The channel setting menu and the channel information bar are displayed at the bottom
of the screen.
After the channel is turned on, modify the parameters such as the vertical scale, the
horizontal time base and the trigger mode according to the input signal to make the
waveform display easy to observe and measure.
*Note: to turn off the channel, press the channel button twice.
Adjust Scale
The vertical scale can be adjusted in Coarse or Fine mode.
•
Coarse adjustment (take counterclockwise as an example): set the vertical scale
in 1-2-5 step namely 2 mV/div, 5 mV/div, 10 mV/div ...10 V/div.
•
Fine adjustment: further adjust the vertical scale within a relatively smaller range
to improve vertical resolution. For example: 2 V/div, 1.98V/div, 1.96V/div, 1.94
V/div ...1 V/div.
•
If the amplitude of the input waveform is a little bit greater than the full scale under
the current scale and the amplitude would be a little bit lower if the next scale is
used, fine adjustment can be used to improve the amplitude of waveform display
to view signal details.
Press the CH1 button on the front panel; then press the Adjust soft key to select the
