How do the probe accessories that I attach my probe to the DUT (Device Under Test) affect the measurement?
Each probe comes with a variety of attachment accessories. Since the specific application for which the probe is to be used for is generally unknown, a set of general-purpose type attachments are included. These generic attachment solutions, however, may not be the proper solution for your specific measurement. Most standard probes and probe accessories are designed for ease of attachment/connection to the DUT. This means that the when accessories are attached to the probe tip, there is generally some degradation in signal acquisition performance. Each time you add a connection to the signal path (probe tip) or the common path (ground or common lead), you change the loading characteristics applied to the device under test. For example: When you add a six-inch ground lead to your system you are adding inductance, capacitance and resistance. The major factor is the inductance (approximately 150 nH). For a one-inch ground you have about 32 nH of inductance. So when you add the ground lead
