Using Probes with the TekProbe II and TekVPI Interfaces. When you attach a probe with the TekProbe II or the
TekVPI interface, the oscilloscope sets the channel sensitivity, coupling, and termination resistance automatically to
match the probe requirements. Tek Probe II probes require use of the TPA-BNC Adapter. TekVPI probes require the use
of a 119‑7465‑XX external power supply.
The Difference Between Vertical Position and Offset. Vertical position is a display function. Adjust the vertical
position to place the waveforms where you want to see them. The waveform baseline locations track adjustments
made to their positions.
When you adjust vertical offset, you see a similar effect, but it is actually quite different. Vertical offset is applied before
the oscilloscope preamplifier and can be used to increase the effective dynamic range of the inputs. For e xample, you
can use vertical offset to look at small variations in a large DC voltage. Set the vertical offset to m atch the nominal DC
voltage and the signal appears in the center of the s creen.
