Extending the Ground Lead

Extending the ground lead will have little, if any, affect on your
measurements. In most circuits, the ground path from the differential
source has sufficiently high impedance to damp out any ringing
caused by lead inductance.

Extending the Probe Output

With the 1103 TekProbe power supply, it is possible to extend the
output of the probe in order to connect the probe to other types of
measurement instruments or simply to connect the probe to a signal
source that is outside the reach of the probe.

Terminating the Probe

The probe must terminate into 50 Ω at the input of the measurement
instrument. Use the 1103 TekProbe power supply to adapt the
differential probe and set the input impedance of the measurement
instrument to 50 Ω. If the measurement instrument does not support
50 Ω input termination, connect a 50 Ω coaxial terminator on the
input.
