Abstract: Test and measurement probes include a body, an adjustable member moveably coupled to the body and having a changeable position relative to the body, and a transducer subsystem structured to measure the position of the adjustable member and configured to output a position signal indicative of the position of the adjustable member. A change in the position of the adjustable member causes a change in an electrical characteristic of the probe. A position-dependent correction factor may be used to correct the change in the electrical characteristic. Methods of compensating for a change in a response of a test and measurement system include monitoring a position sensor output to detect a position change of a first part of a probe relative to a second part, determining that the position sensor output value has crossed a boundary value between a first and second range, and applying a compensation factor corresponding to the second range to modify the response of the system.

Abstract: A test-and-measurement probe (200) for a test-and-measurement instrument (101), the test-and-measurement probe having a probe head (103) and a touchscreen user interface (250). The probe head is configured to obtain a signal from a device under test. The touchscreen user interface is configured to visually convey test-and-measurement information to a user and to accept user touch input. In embodiments, the touchscreen user interface is removably connected to a compbox (105) of the test-and-measurement probe, through a wired connection or wirelessly.
