Refers to a channel input that was successfully compensated at the time Probe Cal was last executed for the input channel.

If no probe is connected, the probe status in the vertical main menu is always initialized.
3
A probe with a simple interface is a probe that can convey very limited information to the oscilloscope. Most passive
probes (such as the P6139A) have simple interfaces.
4
A probe with a TEKPROBE interface is a probe that can convey additional information. For instance, it might automatical-
ly set the oscilloscope input channel impedance to match the probe, send the oscilloscope a unique probe identification
number, and so on. Some optical probes and most active probes (such as the P6205) have TEKPROBE interfaces.
