Probing Basics

Making connection to your device under test is critical to accurate measurements.  Learn the basics parts of the probing system and what they do.

Probe Compensation

In order to insure system signal fidelity it is critical that probes be compensated to the instrument.  Over or under compensated probes can cause distortions of your measurements and bad results.

Signal Acquisition Techniques

Provide an explanation three main data acusition techniques:  Auto Triggering, Normal Triggering, and Single Shot Triggering and explore why you would use each.

High Impedance vs. 50 Ohm Impedance

Explains why 50 Ohm impedance inputs can improve signal fidelity on high speed signals by removing reflections caused by capacitance or inductance.

AC/DC Coupling

AC Coupling removes the DC portion of a signal making it easier to analyze waveforms that have a large DC offset.
