10. Select Probe Setup to de fi ne probe
parameters.
On the side menu:
Select Voltage or Current to set the
probe type for probes that do not
have a TekProbe Level 1, TekProbe II
(requires a TPA-BNC adapter) or TekVPI
interface.
For probes that do not have a Tek
interface, when Probe Type is set to
Voltage , turn Multipurpose a to set
Attenuation to match the probe
For probes that do not have a Tek
interface, when Probe Type is set to
Current , turn Multipurpose a to set the
Amps/Volts ratio (Attenuation) to match
the probe.
If you are measuring current by probing
the voltage drop across a resistor,
set
Measure Current to Yes . Push
A/V ratio on the side menu and turn
Multipurpose a to set the Amps/Volts
or Volts/Amp ratio of your setup. For
example, if you are measuring the drop
across a 2
Ω resistor, set the V/A ratio
to 2.
For some types of probes, you can push
this button to instruct the oscilloscope to
perform an AC calibration on the entire
signal path from the probe tip to the
speci
fi c oscilloscope channel. This can
result in a fl atter frequency response
over the entire frequency range.
11. Select Deskew to make display and
measurement adjustments for probes that
have differing propagation delays. This is
especially important when using a current
probe in conjunction with a voltage probe.
For best results, use a deskew
fi xture, such
as the Tektronix 067-1686-xx.
