Probing Considerations

There are two concerns involved in all probing situations.  The first concern
is probe loading of the target system.  The 16517A/18A probes are designed
to eliminate this problem by providing high impedance from dc to 1 GHz.
The second concern is possible inconsistent or erroneous data capture
caused by lead length and improper signal and ground connections.

The ideal connection is when the probe tip connects directly to the target
system without any additional lead length added to the ground.  Depending
on your measurement, the added inductance caused by additional lead length
may or may not cause a problem for the signal rise time of the target system.
However, try to use the full performance configurations shown below when
possible. If you must add length to the ground lead, use the following general
guidelines:
