Operating Basics
80A03 TekConnectProbe Interface Module Instruction Manual 19
NOTE. Do not connect any other accessory to the sampling oscilloscope Trigger
Probepower port. Doing so may cause confusion that can lead to measurement
errors.
If you use thesampling oscilloscope Trigger Direct input, it is recommended that
you set the triggerlevel on the oscilloscope to 0 volts.
Withthis configuration, you can control the trigger level by directly assigning
the vertical offset for the CH B probe at th e probe tip. Because the offset control
in the probe affectsthe signal level at its output, this method of vertical offset
adjustment providescalibrated trigger level operation.
Tooperate the offset control as a trigger level adjustment, rotate the offset
adjustment on the sampling module channel that has the probeoutput discon-
nected. This will controlthe offset at the probe tip and you can read the trigger
level directlyfrom the offset indicator on the sampling oscilloscope, as shown in
Figure 10.
NOTE. The 2X power divider used in this setupintroduces a vertical scale error
factor of 2.
Sampling Module Incompatibility
Due to SMA cable incompatibility,you cannot directly use 80E01 or 80E06
sampling modules with the 80A03 TekConnectProbe Interface Module. See
page 2 for additional information.
