If you do not have a deskew fixture, you
can use the controls in the Deskew menu to
set the oscill
oscope's deskew parameters
to recommended values, based on the
nominal propagation delay of each probe.
The oscillos
cope automatically loads the
nominal propagation delay values of TekVPI
and TekProbe II (requires use of a TPA-BNC
adaptor) p ro
bes. For other common probes,
first push Select on the side menu, and
select the channel to which the probe is
attached. T
hen push Probe Model on the
side menu, and select the probe model. If
your probe is not in the list, set probe model
to Other,a
nd push Propagation Delay on
the side menu and dial in its propagation
delay with m ultipurpose knob a.
To display
the recommended deskew values
calculated by the oscilloscope, set Show
rec. deskews to Yes on the s ide menu.
To set the
deskew values of each channel
to the recommended values, push Set all

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 P robe II probes require use of the TPA-BNC Adapter.
The Difference Between Vertical Position and Offset. Adjust the vertical position to p lace the w aveforms where you
want to see them. The waveform baseline indicators indicate the zero Volts (or Amps) level for each waveform. If you
adjust the channel's Vertical Scale, the waveform expands or contracts around the waveform's baseline indicator.
When you use the Channel<x> > More >Offset > Vertical Offset control to move a waveform, the baseline indicator
no longer represents zero. Instead, it represents the level of the offset. If you adjust the channel's Vertical Scale, the
waveform expands or contracts around the waveform's baseline indicator.
50 Ω Protection. If you select 50 Ω 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 o scilloscope automatically switches to 1
MΩ termination to protect the i nternal 50 Ω termination. For more details, refer to the specifications in the MSO4000B
and DPO4000B Series Oscilloscopes Technical Reference.
