Coupling

Some probe types allow coupling to reject low frequencies. This will filter out the DC component of a signal
that is composed of a DC bias plus some AC signal. This control is visible only for probe types that have this
capability.

Only some probe types support Offset. For those that do, each probe type has its own Offset setting.
As probes are changed the Offset value will reflect the new probe's setting. Changing the Offset
affects only the current probe type's setting and leaves all others unchanged.
0 V
Saved with probe calibration data. It survives power cycle and is not affected by Preset or Restore.
