Rules for Source Selection
The F6000 software supports a maximum of eight sources at a time.
Apply the following rules for source selection and paralleling:
• A source is not usable if no source name is assigned.
• Voltage sources cannot be paralleled, therefore no duplication of
voltage source names is allowed. The maximum power for
voltage sources is 150 VA.
• The number of usable voltage sources is zero if no source name is
assigned.
• To parallel 150 VA convertible sources when in current mode,
assign the same source name to the sources to be paralleled.
For example, if all three convertible sources in low current mode
are named IA, the three sources in parallel yield 450 VA of power.
If the current range for the paralleled low current source is 3.0 A,
the compliance voltage is 150 V. See Table C.1.
• To parallel 150 VA current sources, assign the same source name
to the sources to be paralleled.
For example, if all three current sources are named I1, the three
sources together yield a single current source rated at 450 VA.
• Only adjacent 150 VA sources can be paralleled. A maximum of
three current sources can be paralleled to create one 450 VA
source.

Low current convertible sources and current sources must not be
paralleled.
• When one 300 VA source and one 150 VA source are needed, the
first two adjacent 150 VA sources supply 300 VA and the third
source supplies 150 VA.
• Each 150 VA source is made up of a pair of 75 VA sources, and
these pairs must remain intact. Therefore a 150 VA source cannot
be paralleled with a 75 VA source from another pair.
• A 150 VA source can be split into two 75 VA sources only if it is
not paralleled with any other source.
• Convertible sources and current sources cannot use the same
source designations.

When using paralleled current sources, it is recommended to parallel
the wiring in order to reduce cable heating and voltage drop.
