Using VERTICAL Controls
3-6 TDS1000B and TDS2000B Series Oscilloscopes – Operator Training Kit
After you set up your oscilloscope for VERTICAL controls,
you can perform various procedures, such as switching the
input coupling of a signal, modifying the vertical scale, and
changing the vertical position of a waveform.
Switching the Input Coupling
Coupling is the method you use to connect an electrical
signal from one device to another. For example, you
implement input coupling when you connect the Training 1
signal board to an oscilloscope. You can select AC, DC, or
Ground coupling on the oscilloscope. The oscilloscope uses
coupling to display components of a waveform in the
following ways:
•
AC coupling blocks the DC component of a signal and
displays only the AC component of the waveform,
centered around 0 volts.
•
DC coupling displays an entire signal as it is, with both
its AC and DC component.
•
Ground coupling disconnects a signal from the vertical
scale and displays a horizontal base line at 0 volts.
