11. Select Probe Setup to de fi ne probe
parameters.
On the resulting side-bezel 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 , use multipurpose knob a to set
Attenuation to match the probe
For probes that do not have a Tek
interface, when Probe Type is set to
Current , use multipurpose knob 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
side-bezel button and turn multipurpose
knob
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.
12. 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.
