Changing the Configuration Between the L match and the
Gamma Topology
filW ARNING:
Maintenance personnel must receive proper training before installing,
troubleshooting, or maintaining high-energy electrical equipment.
Potentially lethal voltages could cause death, serious personal injury, or
damage to the equipment. Ensure that all appropriate safety precautions
are taken.
& DANGER:
RISK OF DEATH OR BODILY INJURY. Disconnect and lockout/tagout all
sources of input power before working on this unit or anything
connected to it.

WARNING:
Leaving on the RF power after turning off the input power to the match
network may damage the unit.
Some ICP units can be operated using either the L match or the Gamma topology,
which allow two different load impedance ranges. By changing the capacitor's
interconnection, you can change the topology of the V arioMatch match network. See
Chapter 3, "Specifications"for a list of part numbers that support this. See
"Topologies" on page 2-4
If your IPC V arioMatch match network supports changing between L Match and
Gamma topologies:
• The default topology, as shipped from the factory, is Gamma (Configuration A).
• Use the instructions in this section to change from Gamma to L match topology.
• The load impedance ranges for each configuration are shown in the Smith
in the Technical Bulletin for your unit. Contact Global Services to obtain the
correct Technical Bulletin.
To change topology, perform the tasks documented in the following sections:
•
"Tools Required to Change the Interconnection" on page 5-28
•
"Disconnecting Power and RF, and Removing the Cover" on page 5-28
