A probe with a simple interface is a probe that can convey very limited information to the oscilloscope. Most passive probes (includ-
ing those shipped with this instrument) have simple interfaces.
4
A probe with a complex interface is a probe that can convey additional information. For instance, it might automatically set the
oscilloscope input channel impedance to match the probe, send the oscilloscope a unique probe identification number, etc. Some
optical probes and most active probes (such as the optional accessory P6205) have complex interfaces.
