Commands Listed in Alphabetical Order
contain a Phase Reference module. If only one such module is installed, the
instrument defaults to the source matching the compartment in which it is installed.
NOTE.
The 82A04B or 82A04 Phase Reference Module can only be installed
in one of the four small-module compartments. A large module installed in the
large CH1/CH2 compartment disables the small CH1/CH2 compartment; a
large module in the large CH3/CH4 compartment disables the small CH3/CH4
compartment. Under these conditions, any Phase Reference Module installed in
the disabled compartments cannot be used.

Arguments
C1C2
selects the fi rst (left-most) small-module compartment as the Phase
Reference Module source. This argument is ineffective if a large module is
installed in the
fi rst (left-most) large module compartment (see note above).
C3C4
selects the second small-module compartment as the Phase Reference
Module source. This argument is ineffective if a large module is installed in
the second large module compartment (see the note above).
C5C6
selects the third small-module compartment as the Phase Reference
Module source.
C7C8
selects the fourth (right-most) small-module compartment as the Phase
Reference Module source.
Examples
PHASEREF:SOURCE C5C6
sets the instrument to use the Phase Reference Module
in the small-module compartment for channels 5 and 6 as the source for the phase
correction timebase.
PHASEREF:SOURCE?
might return
PHASEREF:SOURCE C1C2
, indicating that the
currently selected source is the Phase Reference Module that is installed in the
small-module compartment for channels 1 and 2.
