Input/Output
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.

Example Set the probe to low frequency rejection below 1.7 Hz.
INP:COUP:I LFR1
Notes Only some probe types support Coupling. For those that do, each probe type has its own Coupling
setting. As probes are changed the Coupling value will reflect the new probe's setting. Changing
the Coupling affects only the current probe type's setting and leaves all others unchanged.
Preset DC
State Saved Saved with probe calibration data. It survives a power cycle and is not affected by a Preset or
Restore.

DC
Turns off low frequency rejection, allowing signals down to DC.
