page 481
Sets the OSC voltage level sweep center value to the
difference between the marker and the delta marker
values.
CALC{1-5}:MARK:SET on page 336
Sets the OSC voltage level sweep center value of the
marker.
None
Searches for a peak using the marker and then changes
the CENTER to the OSC voltage level sweep value of
that peak.
Combines the following commands in
execution.
CALC{1-5}:MARK:FUNC:EXEC on

page 482
Sets the OSC voltage level sweep span value to the
difference between the marker and the delta marker
values.
CALC{1-5}:MARK:SET on page 336
Sets the OSC voltage level sweep span value of the
"OSC level span × zooming aperture".
None (No zooming function for the
sweep span.)
Sets the OSC voltage level sweep start value. SOUR2:VOLT:STAR SOUR:VOLT:OFFS:STAR on
page 483
Sets the OSC voltage level sweep start value of the
marker.
CALC{1-5}:MARK:SET on page 336
Sets the dc bias output ON or OFF. SOUR2:VOLT:STAT SOUR:VOLT:OFFS:STAT on
page 484
Sets the OSC voltage level sweep stop value. SOUR2:VOLT:STOP SOUR:VOLT:OFFS:STOP on
page 485
Sets the OSC voltage level sweep stop value of the
marker.
CALC{1-5}:MARK:SET on page 336
Selects the sweep direction when in the dc bias sweep
mode.
SOUR2:SWE:DIR SWE:DIR on page 508
Selects the sweep type in dc bias sweep. SOUR2:SWE:SPAC None (The sweep type for the dc bias
sweep is fixed to a linear sweep.)
