10. Select Probe Setup to dene probe
parameters.
On the side men
u:
Select Voltag
e or Current to set the
probe type for probes that do not
have a TekProbe Level 1, TekProbe II
(requires a T
PA-BNC adapter) or TekVPI
interface.
For probes that do not have a Tek
interface, when Probe Type is set to
Voltage,tu
rn 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,t
urn M u ltipurpose 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 Meas
ure 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 resistor, s et the V/A ratio
to 2.
For som
e types of probes, you can push
this button to instruct the oscilloscope to
perform an AC calibration on the entire
signa
l path from the probe tip to the
specic oscilloscope channel. This can
result in a atter frequency response
over t
he entire frequency range.
11. Select Deskew to make display and
meas
urement adjustments for probes that
have differing propagation delays. This is
especially important when using a current
pro
be in conjunction with a voltage probe.
For best results, use a deskew xture, such
as the Tektronix 067-1686-xx.
