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 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 example you can use vertical offset to look at small variations in a large DC voltage Set the vertical offset to match the nominal DC voltage and the signal appears in the center of the screen 50Q Protection If you select 50 termination the maximum vertical scale factor is limited to 1 V div except that with a 10X probe the scale factor is 10 V If you apply excessive input voltage the oscilloscope automatically switches to 1 MQ termination to protect the internal 50 Q termination For more details refer to the specifications in the Tektronix 4000 Series Oscilloscopes Technical Reference 158 Tektronix 4000 Series Oscilloscopes User Manual Display Wavefor
